PROSPECTUS
- ----------
                             MEDICAL DYNAMICS, INC.

   
                     Up to 1,363,786 Shares of Common Stock
                  Offered for Resale by the Selling Shareholder

     This  Prospectus  relates  to up to  1,363,786  shares of  common  stock of
Medical Dynamics,  Inc., a Colorado  corporation (the "Company" or "MEDY") which
are being  offered and sold by The Tail Wind Fund,  Inc.,  referred to herein as
the "Selling  Shareholder."  The shares being offered by this Prospectus will be
received by the Selling  Shareholder  upon conversion of convertible  securities
and the exercise of warrants  which are defined in greater detail in the section
below entitled "Selling Shareholder," but which are summarized as follows:

     up to 800,000 shares of MEDY's common stock (the "Common  Stock") which are
     issuable  to the  Selling  Shareholder  as a result  of the  conversion  of
     certain  debentures  referred to as the "1998  Debentures" in the aggregate
     principal  amount of  $1,500,000  based on a conversion  price equal to the
     lesser of the  "Ceiling  Price" or of the Market Price (both as defined) on
     the business day immediately preceding the conversion date (the "Conversion
     Shares");

     up to 311,467  shares of the Common Stock which are issuable to the Selling
     Shareholder  as interest on the 1998  Debentures to be calculated at Market
     Price (as defined) (the "Interest Shares");

     up to 150,000 shares  issuable to the Selling  Shareholder on exercise of a
     warrant to purchase  Common Stock  referred to as the "1998  Warrant" at an
     exercise price equal to $2.58 per share (the "Warrant Shares");

     up to 17,704  shares of the Common  Stock which are issuable to the Selling
     Shareholder  as interest on the 1997  Debentures to be calculated at Market
     Price (as defined) (the "Interest Shares"); and
    

     up to 84,615 shares  issuable to the Selling  Shareholder  on exercise of a
     warrant  referred to as the "1997  Warrant"  at an exercise  price equal to
     $3.375 per share (the "Warrant Shares").

     For the purposes of the 1998 and 1997 Debentures, "Market Price" is defined
to mean the average of the two lowest  closing bid prices of the Common Stock as


                                  Page 4 of 33

<PAGE>


reported by The Nasdaq Stock  Market over the 60 trading day period  immediately
preceding  the  determination  date.  As of  November 2, 1998,  Market  Price as
defined in the 1998  Debentures  would be $1.875 per share.  The 1998 Debentures
are  currently  convertible,  and the 1997 and the 1998  Warrants are  currently
exercisable,  subject, however, to the "5% Limitation" which is explained in the
section entitled "Selling Shareholder," below.

   
     For the purposes of the 1998 Debentures, "Ceiling Price" is defined to mean
105% of the average closing bid price of the Common Stock for the twenty trading
days prior to the effective  date of this  registration  statement.  The Ceiling
Price is to be adjusted on July 31,  2000,  to 105% of the Market  Price on that
date if the adjustment  would result in a lower price, but in no event shall the
Ceiling  Price be adjusted  to an amount  less than $2.25.  The number of shares
available for sale by the Selling  Shareholder  has been  estimated  because the
conversion  of the  convertible  securities  will be based in part on the market
price of the Common Stock on the date of conversion.

     MEDY's common stock is traded in the over-the-counter  market and is quoted
on the Nasdaq  SmallCap  Market  under the symbol  "MEDY." On  November 2, 1998,
Nasdaq  reported  that the last sale  price of the  Common  Stock was $2.625 per
share.
    

     The Company  will not receive any  proceeds  from the sale of the Shares by
the Selling  Shareholder,  but will  receive the  exercise  prices  payable upon
exercise of the 1997  Warrants and the 1998  Warrants (if  exercised  for cash).
There can be no assurance that all or any part of the Warrants will be exercised
or that they will be exercised  for cash.  All expenses  incurred in  connection
with this offering (not  including,  however,  commissions  or discounts paid or
allowed by the Selling Shareholder to underwriters,  dealers, brokers or agents)
are being borne by the Company.

     The Selling  Shareholder  has not advised the Company of any specific plans
for the distribution of the Shares, but it is anticipated that the Shares may be
sold from time to time in transactions (which may include block transactions) on
the Nasdaq  SmallCap market at the market prices then  prevailing.  Sales of the
Shares  also may be made  through  negotiated  transactions  or  otherwise.  The
Selling  Shareholder  and the brokers and dealers  though which the sales of the
Shares may be made may be deemed to be  "underwriters"  within the  meaning  set
forth in the  Securities  Act of 1933,  as amended,  and their  commissions  and
discounts and other compensation may be regarded as underwriters'  compensation.
See "Plan of Distribution" commencing at page 20, below.

                               PROSPECTUS SUMMARY
                               ------------------

     The  following  summary is qualified  in its  entirety by the  information,
including the financial statements, referred to elsewhere in this Prospectus.

The Company

     Medical Dynamics,  Inc., a Colorado corporation  incorporated in March 1971
("MEDY" or the "Company"),  is engaged in the design,  development,  manufacture
and  marketing  of medical  and dental  video  cameras  and  related  disposable
products for a variety of professional  specialties.  MEDY's principal  products
are small,  color,  medical and dental video  camera  systems for use in patient
diagnosis and various  surgical  procedures.  MEDY has been  manufacturing  such
cameras  since  August of 1981.  In  October  1997 MEDY  acquired  Computer  Age
Dentist, Inc. (CADI), a California corporation based in Los Angeles, California.
CADI operates as a  wholly-owned  subsidiary  of the Company which  develops and
sells practice management software and related electronic services to the dental
profession.  In February  1998,  through CADI the Company  acquired  Information
Presentation  Systems,  Inc. of Marietta,  Georgia,  one of the nation's largest
suppliers  of  customized  multimedia  systems  for use in a  variety  of dental
operatory environments. In April 1998, through CADI the Company acquired Command
Dental  Systems of  Farmington  Hills,  Michigan,  which  develops  and  markets
turn-key computer systems for the efficient management of dental practices.

     The Company's principal executive offices and manufacturing  facilities are
at 99 Inverness Drive East, Englewood,  Colorado, 80112. Its telephone number at
that address is (303) 790-2990.

The Securities

   
     Currently  the only class of securities of MEDY for which there is a public
market is its Common  Stock.  As of  September  30, 1998,  there were  9,991,739
shares  of  its  Common  Stock  outstanding.  See  "Description  of  Securities"
commencing on page 21, of this Prospectus.
    

The Offering

     Up to 1,363,786  shares of Common Stock (the  "Shares")  are being  offered
hereby by the Selling Shareholder.  These Shares will be received by the Selling
Shareholder upon conversion and exercise of convertible  securities described in
"The 1997  Debentures  and the 1997  Warrants" and "The 1998  Debentures and the
1998 Warrants" under the caption "Selling  Shareholder"  beginning on page 17 of
this  Prospectus.  The  number  of  shares  available  for  sale by the  Selling
Shareholder  has  been  estimated  because  the  conversion  of the  convertible
securities  will be based in part on the market price of the Common Stock on the
date of  conversion.  The Selling  Shareholder  will receive all of the proceeds
from the offer and sale of the Shares.

     The Company  will pay the costs  related to the filing of the  registration
statement in which this Prospectus is included. The Selling Shareholder will pay


                                  Page 10 of 33

its own  expenses  related to the offer and sale of the  Shares,  including  any
underwriter discounts or commissions.



                                  RISK FACTORS
                                  ------------

     The securities  offered hereby are speculative and involve a high degree of
risk,  including,  but not limited to, the risk factors  described  below.  Each
prospective  investor  should  carefully  consider  the  following  risk factors
inherent in and affecting  the business of MEDY and this offering  before making
an investment decision.

   
1.   Losses from Operations.  MEDY has a history of net operating losses, which,
     when  accumulated,  total  $18,117,100  through  June  30,  1998.  This has
     resulted in working  capital  shortages from time to time. MEDY can give no
     assurance  that it will be able to operate  profitably  in the future.  The
     likelihood  of the  success  of MEDY  must be  considered  in  light of the
     problems,  expenses,  difficulties,  complications  and  delays  frequently
     encountered in connection  with the regulatory  environments  in which MEDY
     operates,  the problems related to research and development of new products
     subject  to Food and  Drug  Administration  ("FDA")  and  other  government
     approvals and regulations, and substantial competition from other companies
     as to those  products.  (See the  Financial  Statements  and related  notes
     included in MEDY's  Annual  Report on Form 10-KSB for the fiscal year ended
     September 30, 1997, and subsequent  reports  identified above in "Documents
     Incorporated by Reference", which reports are incorporated by reference.)

2.   Working  Capital  Shortages  and  Dependence on Third Party  Financing.  As
     discussed in MEDY's  Annual Report on Form 10-KSB for the fiscal year ended
     September 30, 1997, and subsequent reports identified, above, in "Documents
     Incorporated  by Reference",  MEDY has regularly  incurred  working capital
     shortages  and has sought to  alleviate  these  shortages  through debt and
     equity financing provided by third party and affiliated investors and, most
     recently,  through a working  capital  line of credit from an  unaffiliated
     bank.  There can be no assurance that such sources of capital will continue
     to be available on terms which are acceptable to MEDY. Eventually MEDY will
     be  required  to finance  its  operations  with its cash flow,  and MEDY is
     attempting  to increase its revenues in an effort to do so. There can be no
     assurance,  however,  that the  working  capital  shortages  which MEDY has
     incurred will not continue and may not adversely  affect MEDY's  ability to
     raise  additional  debt or equity capital if necessary.  (See the Financial
     Statements  and  related  notes  included in MEDY's  Annual  Report on Form
     10-KSB for the fiscal year ended September 30, 1997, and subsequent reports
     identified  above in "Documents  Incorporated by Reference",  which reports
     are incorporated by reference.)

3.   Risk of Dilution from Conversion of Convertible  Debentures.  Assuming full
     conversion  of the 1997 and 1998  Debentures  as of the date  hereof at the
     Market Price set forth on the cover page of this prospectus, 800,000 shares
     
    

                                  Page 11 of 33

<PAGE>


   
     of Common  Stock  would be issued to the  Selling  Shareholder.  This would
     represent  approximately  8% of  the  Common  Stock  which  would  then  be
     outstanding.  Although  this would result in a conversion of a liability on
     MEDY's  balance sheet to equity,  this would result in dilution to existing
     MEDY  shareholders,  many of whom may have  purchased  Common  Stock in the
     over-the-counter  market  at a higher  price  than the  price at which  the
     Selling Shareholder would convert its Debentures. MEDY has the right to pay
     interest on the 1997 and 1998  Debentures in cash or shares of Common Stock
     at Market  Price,  in its  discretion.  To date MEDY has paid  interest  in
     shares of its Common  Stock and  intends to continue to do so in the future
     to conserve  MEDY's  working  capital.  It appears to MEDY that the Selling
     Shareholder  has sold the shares  underlying  the 1997  Debentures  and the
     Interest Shares  pursuant to the existing  registration  statement  shortly
     after converting the 1997 Debentures or receiving the Interest  Shares.  It
     can be expected  that these  sales,  and  perhaps  even the threat of these
     sales, have had a negative impact on the market for the Common Stock.

4.   Product  Liability.  MEDY could be subject to claims for personal  injuries
     resulting  from the use of its  products.  Although  MEDY  carries  product
     liability  insurance  coverage in amounts it  believes  to be  commercially
     reasonable  within its industry,  there can be no assurance that the amount
     of coverage would be sufficient to cover any proven  claims.  Claims proven
     and damages  awarded in excess of the coverage limits would have a material
     adverse effect on MEDY. (See "Item 1 - Business" in MEDY's Annual Report on
     Form 10-KSB for the fiscal year ended  September 30, 1997,  and  subsequent
     reports  identified above in "Documents  Incorporated by Reference",  which
     reports are incorporated by reference.)

5.   Acquisition of New  Businesses.  During the fiscal year ended September 30,
     1998, MEDY has acquired three new businesses. The Company is in the process
     of  integrating  its  accounting,  financial  management,   personnel,  and
     business  functions  with  those  of its new  businesses.  There  can be no
     assurance that MEDY will be able to do so successfully,  or that it will be
     able to do so on a cost  effective  basis.  Based on the experience of more
     than one year since the acquisition of CADI, and more than six months since
     the  acquisition of IPS and CDS, MEDY does not foresee any  difficulties in
     completing  the  integration  of  these  new  businesses.  (See  "Item  1 -
     Business" in MEDY's Annual Report on Form 10- KSB for the fiscal year ended
     September 30, 1997, and subsequent reports identified, above, in "Documents
     Incorporated by Reference", which reports are incorporated by reference.)

6.   Need for  Additional  Financing  and Risk of Dilution.  The Company has not
     generated  earnings in the past several years and there can be no assurance
     that MEDY will be able to do so in the future. Although management believes
     that the capital  available to MEDY is  sufficient  to fund its  short-term
     operations,  it is unable  to  predict  what  additional  expenses  will be
     incurred  beyond  those  contemplated  since  research,   development,  and
     marketing programs frequently involve  unanticipated  expenditures.  To the
     extent  additional  capital  is  needed,  MEDY may seek  financing  through
    
    

                                  Page 12 of 33

<PAGE>


   
     additional  offerings  of equity or debt  securities.  Sales of  additional
     equity   securities  could  dilute  the  ownership   interest  of  existing
     shareholders,   including  investors  in  this  Offering.   Sales  of  debt
     securities would necessarily  result in interest expense and would risk the
     loss of the  Company's  assets  if MEDY  were to  become  unable to pay the
     interest.  Offerings  of debt  securities  also  could  include  conversion
     features  requiring  the issuance of additional  debt or equity  securities
     which,  ultimately,  also could dilute the ownership of prior shareholders,
     including purchasers of the shares being offered by the Selling Shareholder
     in this  Offering.  (See  "Management's  Discussion and Analysis" in MEDY's
     Annual Report on Form 10-KSB for the fiscal year ended  September 30, 1997,
     and  subsequent  reports  identified  above in "Documents  Incorporated  by
     Reference", which reports are incorporated by reference.)

7.   Limitations  on  Ability  to Obtain  Additional  Financing.  The  agreement
     between MEDY and the Selling  Shareholder  contains  limitations  on MEDY's
     ability to raise additional  capital by issuing  convertible debt or equity
     securities  at  prices  which  fluctuate  or  pursuant  to  a  registration
     statement for selling security holders other than the Selling  Shareholder.
     Although  these  restrictions  prohibit the Company  from  raising  working
     capital  or  other  equity  investment  in a  transaction  similar  to  the
     transactions  with the Selling  Shareholder until at least August 1999, the
     Company believes that it will be able to work within these  restrictions to
     the extent it needs additional capital. As recently announced in a Form 8-K
     reporting an event of October 9, 1998,  the Company has entered into a line
     of credit  with an  unaffiliated  bank  which  does not  conflict  with the
     capital  raising  limitations  contained in the agreement  with the Selling
     Shareholder.
    

8.   Technological  Change and Risk of Technological  Obsolescence.  The medical
     and dental camera industry and the dental practice management industry, the
     Company's  two  principal  lines of  business,  are  subject  to rapid  and
     significant  technological  change.  Accordingly,  MEDY's viability will be
     dependent  on  its  ability  to  introduce   competitive  products  to  the
     marketplace in a timely manner and enhance and improve such products to its
     customers'  satisfaction.  There can be no assurance that MEDY will be able
     to keep pace with technological  developments or that its products will not
     become  obsolete.  (See "Item 1 Business" in MEDY's  annual  report on Form
     10-KSB for the fiscal year ended September 30, 1997, and subsequent reports
     identified  above in "Documents  Incorporated by Reference",  which reports
     are incorporated by reference.)

9.   Competition  -- MEDY and CADI.  MEDY's  operations  and  product  lines are
     subject to a high level of competition  from foreign,  as well as domestic,
     manufacturers  of color  medical and dental video cameras and other medical
     devices  which are currently  manufactured  and sold by MEDY, or which MEDY
     may develop in the  future.  Some  competitors  are  affiliated  with large
     companies with substantial  economic and personnel  resources which greatly
     exceed those of MEDY.  There can be no assurance  that MEDY will be able to
     compete successfully with other companies.


                                  Page 13 of 33

<PAGE>



   
     In addition, there are a large number of competitors in the dental practice
     management area. Most of these competitors are smaller  businesses,  and to
     MEDY's knowledge CADI is the largest supplier of dental practice management
     software in the United States. CADI's software is Y2K compliant, unlike the
     software offered by some of CADI's competitors.  There can be no assurance,
     however,  that  competitors  may not reduce CADI's market share by offering
     their  proprietary  version of dental practice  management  software.  CADI
     plans to compete with these other  businesses  by continuing to upgrade its
     software and by continuing to package the dental practice  software it with
     a complete office system of hardware and software.
    

     (See "Item 1 -  Business"  in MEDY's  annual  report on Form 10-KSB for the
     fiscal year ended  September 30, 1997,  and subsequent  reports  identified
     above  in  "Documents   Incorporated  by  Reference",   which  reports  are
     incorporated by reference.)

   
10.  Potential Conflicts of Interest.  There have been significant  conflicts of
     interest in the operation and management of MEDY, including the purchase by
     MEDY of certain  equipment  and patents from its  directors  and  executive
     officers,  granting of royalties,  loans made available to MEDY through its
     Chairman,  and the  employment by MEDY of sons of two of MEDY's  directors.
     These transactions were not negotiated at arms' length,  although the Board
     of Directors  believes that all of these  transactions  were fair to and in
     the best interests of MEDY. Although MEDY uses its best efforts to minimize
     conflicts of interest,  the existence of such  conflicts may impact MEDY in
     its business  activities.  (See "Item 1 - Business"  and "Item 13 - Certain
     Relationships  and Related  Transactions"  in MEDY's  Annual Report on Form
     10-KSB for the fiscal year ended September 30, 1997, and subsequent reports
     identified  above in "Documents  Incorporated by Reference",  which reports
     are incorporated by reference.)
    

11.  Dependence on Management. At present, the success of MEDY is dependent upon
     the active  participation of its management,  MEDY's Chairman and principal
     shareholder,  Dr. Adair, and its Chief Executive Officer,  Van Horsley, Dr.
     Adair's  step-son.  CADI's  operations are  significantly  dependent on the
     continued  availability  of the services of Daniel L.  Richmond and Chae U.
     Kim. The loss of the services of any of these persons would have a material
     adverse effect on the Company.  In the event of such a loss,  MEDY can give
     no  assurance  that  it  could  replace  either  person  without  incurring
     substantial  additional  expense.  MEDY does not have employment  contracts
     with either Mr.  Horsley or Dr.  Adair.  Both Messrs.  Richmond and Kim are
     subject to five year  employment  agreements.  (See "Item 1 - Business"  in
     MEDY's Annual Report on Form 10-KSB for the fiscal year ended September 30,
     1997, and subsequent reports identified above in "Documents Incorporated by
     Reference", which reports are incorporated by reference.)

12.  Government   Regulation.   Because   certain  of  the  products  that  MEDY
     manufactures  are used in  surgery  and  other  medical  applications,  the
     products are subject to  regulations  of and close  scrutiny by agencies of
     

                                  Page 14 of 33

<PAGE>


   
     the federal government,  including the FDA. Although MEDY believes that its
     facilities are in compliance with all applicable regulations, MEDY can give
     no  assurance  that  it  will  be able  to  comply  fully  with  all of the
     government  regulations to which it is subject.  Failure to comply strictly
     with all FDA  requirements  (not all of which are  written)  may  result in
     sanctions as severe as the cessation of MEDY's manufacturing business which
     would  have a  material  adverse  effect  on  MEDY.  Although  MEDY has had
     difficulty  in certain  instances in the past in obtaining  FDA approval on
     new products,  MEDY's current business in not materially  dependent on this
     issue and,  therefore,  this is not deemed to be a significant  risk.  (See
     "Item 1 - Business" in MEDY's  Annual  Report on Form 10-KSB for the fiscal
     year ended September 30, 1997, and subsequent  reports  identified above in
     "Documents  Incorporated by Reference",  which reports are  incorporated by
     reference.)
    

13.  Protection of Technology. Although MEDY obtains secrecy agreements from its
     employees  and others  having access to its trade secrets and holds patents
     on certain of its  technology,  such  agreements  and patents do not afford
     complete  protection  against the  unauthorized  use of such information by
     others. Furthermore,  the costs of prosecuting persons who may accidentally
     or  intentionally  infringe on MEDY's  patents or divulge its trade secrets
     can be expensive and time consuming.  The  unauthorized use of MEDY's trade
     secrets and the  infringement of its patents could have a material  adverse
     effect on MEDY and its  ability to  compete.  (See "Item 1 -  Business"  in
     MEDY's Annual Report on Form 10-KSB for the fiscal year ended September 30,
     1997, and subsequent reports identified above in "Documents Incorporated by
     Reference", which reports are incorporated by reference.)

   
14.  Significant   Investment  in  Intangible   Assets.   As  a  result  of  the
     acquisitions  of CADI,  IPS and CDS, MEDY has a  significant  investment in
     intangible  assets,  amounting to  approximately  $4,700,000 (59% of MEDY's
     total assets).  The expenses associated with the annual amortization of the
     intangible  assets  will make it more  difficult  for MEDY to  realize  net
     income.  Because intangible assets are incapable of precise  valuation,  it
     may be necessary  for MEDY to reduce the balance  sheet  valuation of these
     assets at some later point,  although  MEDY has no intention or basis to do
     so at the present  time.  (See MEDY's  Annual Report on Form 10-KSB for the
     fiscal year ended  September 30, 1997,  and subsequent  reports  identified
     above  in  "Documents   Incorporated  by  Reference",   which  reports  are
     incorporated by reference.)

15.  Limited Public  Market;  Price  Volatility;  and No Assurance of Liquidity.
     There  currently is a limited  public market for MEDY's  Common  Stock.  No
     assurance  can be given that a market for the  Common  Stock will  continue
     subsequent to this offering or that purchasers will be able to resell their
     securities at the purchase prices paid in this Offering, or liquidate their
     investment  without  considerable  delay,  if  at  all.  If a  market  does
     continue, the price may be highly volatile. Factors such as those discussed
     in this "Risk Factors" section may have a significant  impact on the market
     price of the securities offered.  Also, some brokerage firms may not effect
     transactions in securities that trade below a stipulated price.
    

                                  Page 15 of 33

<PAGE>



     Further, most lending institutions will not permit the use of low-priced or
     thinly traded securities as collateral for loans.

   
16.  Dependence on Principal Customers.  In the past, MEDY has been dependent on
     a limited  number of  principal  customers.  During the 1997  fiscal  year,
     MEDY's  principal  customer which  accounted for 61% of MEDY's revenues was
     Information Presentation Systems, Inc., of Marietta, Georgia. IPS purchased
     certain of MEDY's  camera  products and  packaged  the products  with other
     hardware and software,  including CADI's software, for resale. As described
     elsewhere in this Prospectus,  MEDY, though CADI,  acquired IPS in February
     1998.  (See MEDY's  Annual  Report on Form 10-KSB for the fiscal year ended
     September  30,  1997,  "Item  1 -  Business"  and  Item  6 -  "Management's
     Discussion  and Analysis of Financial  Condition and Results of Operations"
     therein, and subsequent reports identified above in "Documents Incorporated
     by Reference",  which reports are incorporated by reference.)  which report
     is  incorporated by reference).  As a result of the IPS acquisition  during
     the 1998 fiscal  year,  the  Company  does not expect that it will have any
     single  customer  accounting for more than 10% of its sales during the 1998
     or  subsequent  fiscal  years,  although it is  possible  that there may be
     significant customers in future fiscal years.
    

17.  No Dividends Paid or  Contemplated.  No dividends have been paid by MEDY in
     the past and  dividends are not  contemplated  in the  foreseeable  future.
     Investors who anticipate  the need of either  immediate or future income by
     way of dividends from their investment  should refrain from the purchase of
     Shares offered hereby.

   
18.  Year 2000  Compliance.  Although  there can be no assurance,  MEDY does not
     anticipate  that it will suffer any adverse impact as a result of Year 2000
     (Y2K)  computer   software  issues  either  as  a  result  of  third  party
     non-compliance or as a result of internal matters.  None of the information
     technology or other software and hardware  systems utilized by MEDY and its
     subsidiaries incorporates technology that is incapable of recognizing dates
     beyond December 31, 1999.  CADI,  through its internal staff, has developed
     its dental  practice  management  software  for the Windows  platform  and,
     consequently,  such  software  recognizes  dates beyond  December 31, 1999.
     While  CADI is  still  supporting  some  software  which  is  DOS-based  or
     otherwise may not be Y2K compliant,  the customers using this software have
     been advised of their need to upgrade their office software in anticipation
     of Y2K. Even if MEDY or CADI were to provide the necessary software upgrade
     to these  customers at no cost (which CADI does not have an  obligation  to
     do),  the total loss to MEDY would be less than  $60,000 in revenues and is
     not considered to be material.  Because CADI's dental  practice  management
     software is Y2K  compliant,  CADI and MEDY  believe that this offers them a
     marketing opportunity in that much of their competitors' software currently
     being  utilized by dental  offices is not Y2K compliant and will need to be
     replaced  by those  offices  before  December  31,  1999.  There  can be no
     assurance,  however,  that these offices will all purchase  dental practice
     management systems from CADI.

                                 ---------------



     The Selling  Shareholder  will  receive all  proceeds  from the sale of the
Shares offered and sold under this Prospectus.

     If, and to the extent,  the 1997 and 1998  Warrants are exercised for cash,
the Company will receive  proceeds equal to the aggregate  exercise price of the
warrants,  approximately $672,600 if all of the warrants are exercised for cash.
The 1997 and 1998 Warrants  allow the holder to effect a "cashless"  exercise of
the  Warrants.  These  warrants  are  described  under  the  captions  "The 1997
Debentures  and  Warrants"  and  "The  1998  Debentures  and  Warrants"  in this
Prospectus under "Selling  Shareholder."  Any proceeds the Company receives from
the exercise of these warrants will be used for working capital.

                                   THE COMPANY
                                   -----------

   
     Medical Dynamics,  Inc., a Colorado corporation  incorporated in March 1971
(referred  to herein as "MEDY" or the  "Company"),  is  engaged  in the  design,
development,  manufacture  and marketing of medical and dental video cameras and
related disposable  products for a variety of professional  specialties.  MEDY's
principal products are small, color, medical and dental video camera systems for
use in  patient  diagnosis  and  various  surgical  procedures.  MEDY  has  been
manufacturing  such cameras  since August of 1981. In October 1997 MEDY acquired
100% of the outstanding  capital stock of Computer Age Dentist,  Inc.  (CADI), a
California corporation based in Los Angeles,  California. CADI is engaged in the
development  and sale of Practice  Management  Software  and related  electronic
services  to the dental  profession.  In February  1998 CADI  acquired by merger
Information  Presentation  Systems,  Inc. of  Marietta,  Georgia,  a supplier of
customized  multimedia  systems  for  use  in  a  variety  of  dental  operatory
environments.  In April 1998,  CADI acquired by merger Command Dental Systems of
Farmington Hills, Michigan, which develops and markets turn-key computer systems
for the efficient management of dental practices.  In reviewing MEDY's financial
statements which are incorporated herein by reference, it should be noted that a
substantial  portion of the Company's  revenues for fiscal 1998 derives from the
businesses  acquired by MEDY during  fiscal 1998 and not from MEDY's  historical
businesses of medical and dental camera manufacturing.

     MEDY's principal  executive offices and manufacturing  facilities are at 99
Inverness Drive East, Englewood,  Colorado,  80112. Its telephone number at that
address is (303) 790-2990.
    

                               SELLING SHAREHOLDER
                               -------------------

     The Tail Wind Fund, Ltd. ("Tail Wind" or the "Selling  Shareholder") is not
an affiliate of MEDY,  nor has the Selling  Shareholder  or any affiliate of the
Selling Shareholder had any position, office or other material relationship with
MEDY  within  the past three  years,  except as  disclosed  below.  Tail  Wind's
business address is Windermere House, P.O. Box SS-5539, Nassau, Bahamas.

     Of the Shares  offered  hereby,  _____________  have been  issued  upon the
conversion of certain of the 1997  Debentures but not yet sold by Tail Wind. The


                                  Page 17 of 33

balance are issuable upon the conversion of the outstanding  1998 Debentures (of
which  $1,500,000  in face  amount are  outstanding),  the  payment of  interest
related  thereto and upon the exercise of the 1997 and 1998 Warrants.  There are
no 1997 Debentures remaining to be converted as of November 5, 1998. The Selling
Shareholder  does not own,  directly or  indirectly,  any other shares of Common
Stock.  Assuming that the Selling  Shareholder  sells all Shares offered hereby,
although  there is no  requirement  that it do so, it will  beneficially  own no
shares of Common Stock at the conclusion of the Offering.

     The exact  number of shares to be offered and sold is not known at the date
of this  Prospectus  because  the shares  will be acquired  upon  conversion  of
convertible  securities at varying prices, most of which will be converted based
on the market price of the Common Stock on the date of conversion. Were the 1998
Debentures  converted in full at the Market Price set forth on the cover page of
this Prospectus and the 1997 and 1998 Warrants  exercised in full, the following
number of shares of Common Stock would be issued:

     1997 Warrants             84,615 shares of Common Stock, exercisable
                               through October 31, 2000 at a price of $3.375 per
                               share
     1998 Debentures           800,000 shares
     1998 Warrants             150,000  shares  of Common
                               Stock,  exercisable through July 31,
                               2003 at a price of $2.58 per share,

The Selling  Shareholder  has agreed that it will at no time own more than 4.99%
of the Common Stock.  This  limitation  prohibits the Selling  Shareholder  from
converting the convertible securities or exercising the 1997 or 1998 Warrants to
the extent that  conversion or exercise would result in the Selling  Shareholder
owning  more than 4.99% of the issued and  outstanding  shares of Common  Stock.
This limitation is referred to in this  Prospectus as the "5%  Limitation." As a
result of the 5%  Limitation  and  pursuant  to SEC Rule  13d-4,  , the  Selling
Shareholder  disclaims  beneficial  ownership  of all shares to the extent  such
ownership  would result in it  exceeding  the 5%  Limitation.  If all the Shares
being offered by the Selling  Shareholder are sold, the Selling Shareholder will
own no shares of the  Company's  common stock  following  the  completion of the
Offering.
    

     The  following is a  description  of the  transaction  in which the Selling
Shareholder   acquired  the  convertible   securities  which,  if  converted  or
exercised,  will result in the  issuance of the Shares  offered for sale in this
Prospectus by the Selling Shareholder.

The 1997 Debentures and Warrants

   
     On October 31, 1997, in a private  placement  offering under  Regulation D,
the Selling Shareholder purchased debentures in an aggregate principal amount of
$1,100,000  (the  "1997  Debentures").  All of the  1997  Debentures  have  been
converted  as of the date hereof  into a total of 520,349  shares of MEDY Common
Stock.
    


                                  Page 18 of 33

<PAGE>

     In connection with Tail Wind's purchase of the 1997 Debentures, the Company
issued to Tail Wind  warrants to purchase up to 84,615  shares of Common  Stock,
exercisable  through  October 31, 2000 at a price of $3.375 per share (the "1997
Warrants").  The 1997 Warrants contains standard anti-dilution provisions should
MEDY issue stock dividends or conduct a stock split or  reorganization,  or upon
occurrence  of certain  other  events.  Subject to the 5%  Limitation,  the 1997
Warrants are currently exercisable.

The 1998 Debentures and Warrants

   
     On July 31, 1998, in a private  placement  offering under Regulation D, the
Selling  Shareholder  purchased  debentures in an aggregate  principal amount of
$1,100,000  and,  on  November  ___,  1998,  purchased  an  additional  $400,000
principal amount (the "1998  Debentures").  The 1998 Debentures bear interest at
8% per annum,  with interest  payable  semi-annually  on January 5 and July 5 of
each year, commencing January 5, 1999. Principal and accrued but unpaid interest
is due in full on July 31,  2003.  Events of default  under the 1998  Debentures
which could result in acceleration of amounts due, among other things,  include:
(i) failure to pay any amounts of principal or interest  when due;  (ii) failure
of the  Common  Stock to be listed on the  Nasdaq  SmallCap  Market,  the Nasdaq
National  Market,  the New York Stock Exchange,  or the American Stock Exchange;
and/or (iii) events of bankruptcy and similar events.

     The Company may, at its option, pay accrued interest on the 1998 Debentures
with  shares of its Common  Stock  valued at Market  Price.  Based on the Market
Price set forth on the  cover  page of this  Prospectus,  assuming  all  accrued
interest on the 1998  Debentures  is paid in shares of Common Stock and that the
1998  Debentures  are  held  to  maturity,   the  Company  will  pay  Tail  Wind
approximately 311,467 shares of Common Stock (the "1998 Interest Shares").

     Tail Wind is entitled to convert the 1998 Debentures,  in whole or in part,
into shares of Common Stock at the lesser of Market Price or the "Ceiling Price"
at any time  from  and  after  November  29,  1998 as to  one-third  of  the1998
Debentures,  on and  after  January  27,  1999  as to  two-thirds  of  the  1998
Debentures,  and on and after  March 29,  1999 as to the full amount of the 1998
Debentures.  For purposes of the 1998 Debentures,  "Ceiling Price" means 105% of
the  average  closing  bid price of the  Common  Stock for the 20  trading  days
immediately  preceding the effective  date of this  registration  statement.  If
conversion has not occurred by July 31, 2000, the Ceiling Price  thereafter will
mean 105% of the Market Price on July 31, 2000 if the adjustment would result in
a lower price,  except that the Ceiling  Price will not be adjusted  below $2.25
per share.  Assuming that Tail Wind can and elects to convert the full amount of
the 1998 Debentures  into shares of Common Stock,  based on the Market Price set
forth on the cover  page of this  Prospectus,  Tail Wind would  receive  800,000
shares of Common Stock (the "1998 Conversion Shares").
    

     In connection  with Tail Wind's purchase of the 1998 Debentures in July and
November  1998,  the  Company  issued to Tail Wind  warrants to purchase up to a
total of 150,000 shares of Common Stock,  exercisable through July 31, 2003 at a
price of $2.58 per share  (the  "1998  Warrants").  The 1998  Warrants  contains


                                  Page 19 of 33

<PAGE>


anti-dilution  provisions  should MEDY issue stock  dividends or conduct a stock
split or reorganization,  or upon occurrence of certain other events. Subject to
the 5% Limitation, the 1998 Warrants are currently exercisable.

     If MEDY is  unable to meet the  effectiveness  requirement  for the  shares
underlying the 1998  Debentures  and Warrants,  maintain  effectiveness  of this
registration  statement,  or  maintain  the  listing of the Common  Stock on the
Nasdaq  SmallCap  or the NMS  Market (or senior  stock  exchange),  MEDY will be
required to pay liquidated damages to the Selling Shareholder in an amount equal
to 2% of the aggregate principal amount of the 1998 Debentures for each month or
portion  thereof  following  the  required  effectiveness  date during which the
registration  statement  is not  effective.  In such event,  MEDY shall bear all
reasonable  fees or costs incurred by Tail Wind for legal counsel as a result of
the filing of any post-effective  amendments to the Registration Statement.  The
amounts  payable as  liquidated  damages  pursuant  to this  paragraph  shall be
payable in cash (not Common Stock).  The registration  rights agreement contains
standard  cross-indemnification  provisions and  requirements  for  contribution
should the indemnification provisions be found to be unavailable.


                              PLAN OF DISTRIBUTION
                              --------------------

     The Selling Shareholder has advised MEDY that it may sell the Shares in one
or more transactions  (which may involve one or more block  transactions) on the
over-the-counter  markets on Nasdaq and upon terms then  prevailing or at prices
related  to  the  then  current  market  price,  or  in  separately   negotiated
transactions or in a combination of such transactions. The Shares offered hereby
may be sold by one or more of the following methods,  without limitation:  (a) a
block  trade in which a broker or dealer so  engaged  will  attempt  to sell the
shares as agent but may  position and resell a portion of the block as principal
to facilitate the transaction;  (b) purchases by a broker or dealer as principal
and resale by such broker or dealer for its account pursuant to this Prospectus;
(c)  ordinary  brokerage  transactions  and  transactions  in which  the  broker
solicits purchasers; (d) privately negotiated transactions; and (e) face-to-face
transactions between sellers and purchasers without a broker-dealer. The Selling
Shareholder  may  also  sell  Shares  in  accordance  with  Rule 144  under  the
Securities Act of 1933, as amended,  if Rule 144 is then available.  The Selling
Shareholder  may be deemed to be an  underwriter  of the Shares  offered  hereby
within the meaning of the Securities Act of 1933, as amended.

     In effecting sales,  brokers or dealers engaged by the Selling  Shareholder
may arrange for other brokers or dealers to participate.  Such broker or dealers
may receive  commissions or discounts from the Selling Shareholder in amounts to
be negotiated by the Selling Shareholder. The Selling Shareholder may enter into
hedging  transactions with  broker-dealers  and the broker-dealers may engage in
short  sales of the Common  Stock in the course of hedging  the  positions  they
assume  with  the  Selling  Shareholder  (including,   without  limitation,   in
connection with the  distribution  of the Common Stock by such  broker-dealers).
The Selling  Shareholder  may also engage in short sales of the Common Stock and
may enter into option or other transactions with broker-dealers that involve the
delivery  of the  Common  Stock to the  broker-dealers,  who may then  resell or
otherwise  transfter  such  Common  Stock.  Such  broker-dealers  and any  other


                                  Page 20 of 33

<PAGE>


participating broker-dealers may, in connection with such sales, be deemed to be
underwriters  within the meaning of the Securities Act of 1933, as amended.  Any
discounts or commissions received by any such broker-dealers may be deemed to be
underwriting  discounts and  commissions  under the  Securities  Act of 1933, as
amended.

     In  order  to  comply  with  the  securities  laws of  certain  states,  if
applicable,  the  Shares  will  be  sold  in  such  jurisdictions  only  through
registered or licensed broke-dealers.

     MEDY  will  pay  all  of  the  expenses  incident  to the  filing  of  this
Registration  Statement,  estimated to be $25,000.  These expenses include legal
and  accounting  fees in connection  with the  preparation  of the  Registration
Statement of which this Prospectus is a part, legal and other fees in connection
with the  qualification  of the sale of the  Shares  under  the laws of  certain
states (if any),  registration  and filing fees,  printing  expenses,  and other
expenses.  The Selling  Shareholder will pay all other expenses  incident to the
offering  and  sale of the  Shares  to the  public,  including  commissions  and
discounts of underwriters,  brokers,  dealers or agents, if any. MEDY has agreed
to use its best efforts to keep the  registration  of the Shares  offered hereby
effective  until the date upon  which all of the Shares  offered by the  Selling
Shareholder have been sold.

                            DESCRIPTION OF SECURITIES
                            -------------------------

Common Stock

     Authorized. MEDY is authorized to issue 30,000,000 shares of $.01 par value
common stock (the "Common  Stock").  No holder of any shares of Common Stock has
any preemptive right to subscribe to any of MEDY's securities. Upon dissolution,
liquidation  or winding up of MEDY,  the  assets  will be divided  pro rata on a
share-for-share  basis among holders of the shares of Common Stock and Preferred
Stock if any shares are outstanding.  All shares of Common Stock outstanding are
fully paid and nonassessable and, when issued, the shares offered hereby will be
fully paid and nonassessable.

     Issued and Outstanding. On August 31, 1998, MEDY had issued and outstanding
9,991,739  shares of Common  Stock.  This  number  does not  include  any of the
estimated  2,449,532 shares comprising the 1997 and 1998 Conversion  Shares, the
1997 and 1998 Interest Shares and the 1997 and 1998 Warrant Shares which, if and
when issued, will be offered for sale pursuant to this Prospectus by the Selling
Shareholder.  For information about these shares, see the description  contained
under the caption "Selling Shareholder" above.

     Dividends.  Holders of Common Stock are entitled to dividends  when, as and
if declared by the Board of Directors out of funds legally  available  therefor,
subject to the rights, if any, of holders of any outstanding shares of Preferred
Stock.  MEDY has not declared or paid any dividends on its Common Stock and does
not  anticipate  the  declaration  or payment of  dividends  in the  foreseeable
future.

     No Cumulative  Voting.  Each holder of Common Stock is entitled to one vote
per share with  respect to all matters  that are required by law to be submitted
to stockholders.

                                  Page 21 of 33

<PAGE>



The  stockholders  are not  entitled  to  cumulative  voting in the  election of
directors.  Accordingly,  the holders of more than 50% of the shares  voting for
the election of directors  can elect 100% of the  directors if they choose to do
so; and, in such event, the holders of the remaining less than 50% of the shares
voting for the election of the  directors  will be unable to elect any person or
persons to the Board of Directors.

     No  Preemptive  Rights.  Holders  of  Common  Stock  are  not  entitled  to
preemptive rights to purchase additional shares of Common Stock when offered for
sale by the Company.

Preferred Stock

     MEDY is  authorized  to issue up to  5,000,000  shares  of $.001  par value
Preferred  Stock,  in series to be  designated  by the Board of  Directors  (the
"Preferred  Stock"). No shares of Preferred Stock have been issued and it is not
contemplated  that any shares of  Preferred  Stock will be issued by MEDY in the
immediate  future;  however,  the Board may use its  ability to issue  Preferred
Stock to effect the business purposes of MEDY.

     Material  provisions  concerning the terms of any series of Preferred Stock
such as dividend rate, conversion features and voting rights, will be determined
by the Board of Directors of MEDY at the time of such  issuance.  The ability of
the  Board to issue  Preferred  Stock  also  could be used by MEDY as a means of
resisting a change of control of MEDY and,  therefore,  could be  considered  an
"anti-takeover" device.

1997 and 1998 Debentures and Warrants

     For a description of these  securities,  see "1997 Debentures and Warrants"
and "1998  Debentures and Warrants" under the caption  "Selling  Shareholder" in
this Prospectus.

Stock Options

     Exclusive  of the 1997  Warrants and the 1998  Warrants,  on July 31, 1998,
MEDY had outstanding stock options to purchase  3,801,237 shares of Common Stock
exercisable  at  exercise  prices  ranging  between  $1.00 and $4.50 per  share.
Certain of these options are only exercisable upon the Company achieving certain
performance goals.

Transfer and Warrant Agent

     The transfer  agent for MEDY's  Common  Stock and Warrant  Agent for MEDY's
Common Stock is  Continental  Stock  Transfer & Trust Co., 72 Reade Street,  New
York, New York 10007.

Item 15. Indemnification of Directors and Officers.
         ------------------------------------------

     Section  7-109-102 of the Colorado  Revised  Statutes and the  Registrant's
Articles  of  Incorporation,   under  certain   circumstances  provide  for  the
indemnification of the Registrant's officers,  directors and controlling persons
against liabilities which they may incur in such capacities.  A summarization of
the  circumstances  in which such  indemnification  is provided for is contained
herein,  but that  description  is qualified in its entirety by reference to the
Registrant's  Articles of Incorporation and the relevant Section of the Colorado
Revised Statutes.

     In general,  the statute  provides  that any  director  may be  indemnified
against  liabilities  (including the  obligation to pay a judgment,  settlement,
penalty,  fine or  expense),  incurred  in a  proceeding  (including  any civil,
criminal  or  investigative  proceeding)  to which the  director  was a party by
reason of such status.  Such indemnity may be provided if the director's actions
resulting in the liabilities: (i) were taken in good faith; (ii) were reasonably
believed to have been in the Registrant's  best interest with respect to actions
taken in the director's official capacity; (iii) were reasonably believed not to
be opposed to the Registrant's best interest with respect to other actions;  and
(iv) with respect to any criminal action, the director had no reasonable grounds
to believe the actions were unlawful. Unless the director is successful upon the
merits in such an action,  indemnification may generally be awarded only after a
determination  of  independent  members of the Board of Directors or a committee
thereof,  by independent  legal counsel or by vote of the shareholders  that the
applicable standard of conduct was met by the director to be indemnified.

     The  statutory   provisions  further  provide  that  unless  limited  by  a
corporation's  articles  of  incorporation,  a director or officer who is wholly
successful, on the merits or otherwise, in defense of any proceeding to which he
as a party, is entitled to receive  indemnification against reasonable expenses,


                                  Page 25 of 33

<PAGE>


including  attorneys'  fees,  incurred in  connection  with the  proceeding.  In
addition,  a  corporation  may  indemnify  or advance  expenses  to an  officer,
employee or agent who is not a director to a greater  extent than  permitted for
indemnification of directors,  if consistent with law and if provided for by its
articles of incorporation,  bylaws,  resolution of its shareholders or directors
or in a  contract.  The  provision  of  indemnification  to  persons  other than
directors  is subject to such  limitations  as may be imposed on general  public
policy grounds.

     In addition to the foregoing,  unless hereafter limited by the Registrant's
articles of incorporation, a court, upon petition by an officer or director, may
order the Registrant to indemnify such officer or director  against  liabilities
arising in connection with any  proceeding.  A court may order the Registrant to
provide such indemnification,  whether or not the applicable standard of conduct
described   above  was  met  by  the   officer  or   director.   To  order  such
indemnification  the court  must  determine  that the  petitioner  is fairly and
reasonably entitled to such indemnification in light of the circumstances.  With
respect  to  liabilities  arising  as a result of  proceedings  on behalf of the
Registrant,  a court may only require that a petitioner be indemnified as to the
reasonable expenses incurred.

     Indemnification  in connection  with a proceeding by or in the right of the
Registrant in which the director is successful is permitted only with respect to
reasonable  expenses  incurred in connection with the defense.  In such actions,
the person to be indemnified must have acted in good faith, in a manner believed
to have been in the  Registrant's  best interest and must not have been adjudged
liable for negligence or misconduct.  Indemnification is otherwise prohibited in
connection  with a  proceeding  brought on behalf of the  Registrant  in which a
director  is  adjudged  liable  to the  Registrant,  or in  connection  with any
proceeding  charging  improper  personal  benefit to the  director  in which the
director is adjudged liable for receipt of an improper personal benefit.

     Colorado law  authorizes  the  Registrant  to  reimburse or pay  reasonable
expenses incurred by a director, officer, employee or agent in connection with a
proceeding,  in advance of a final  disposition of the matter.  Such advances of
expenses  are  permitted  if the person  furnishes  to the  Registrant a written
statement of his belief that he met the applicable  standard of conduct required
to permit such  indemnification.  The person seeking such expense  advances must
also provide the Registrant  with a written  agreement to repay such advances if
it is determined the applicable standard of conduct was not met. A determination
must also be made  that the facts  known to the  Registrant  would not  preclude
indemnification.

     The statutory section cited above further specifies that any provisions for
indemnification  of or advances for expenses to directors which may be contained
in the  Registrant's  Articles  of  Incorporation,  Bylaws,  resolutions  of its
shareholders  or directors,  or in a contract  (except for  insurance  policies)
shall be valid  only to the  extent  such  provisions  are  consistent  with the
Colorado  statutes and any  limitations  upon  indemnification  set forth in the
Articles of Incorporation.

     The statutory provision cited above also grants the power to the Registrant
to purchase and maintain insurance policies which protect any director, officer,
employee,  fiduciary or agent against any liability asserted against or incurred
by them in such  capacity  arising out of his status as such.  Such policies may
provide for indemnification  whether or not the corporation would otherwise have


                                  Page 26 of 33

<PAGE>


the power to  provide  for it. No such  policies  providing  protection  against
liabilities  imposed  under  the  securities  laws  have  been  obtained  by the
Registrant.  The registration rights agreements dated July 31, 1998, and October
31,  1997   between  the   Registrant   and  Tail  Wind.,   provides  for  cross
indemnification  by the  Registrant  and Tail Wind,  in  certain  circumstances,
including for certain securities laws violations.

Item 17. Undertakings.
- ----------------------

     The  undersigned  Registrant  hereby  undertakes:  (1) to file,  during any
period in which  offers or sales are being made, a  post-effective  amendment to
the Registration  Statement:  (i) to include any prospectus  required by Section
10(a)(3) of the  Securities  Act of 1933;  (ii) to reflect in the prospectus any
facts or events arising after the effective date of the  Registration  Statement
(or the most recent post-effective amendment thereof) which,  individually or in
the aggregate,  represent a fundamental  change in the  information set forth in
the Registration  Statement;  and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in the Registration
Statement  or any  material  change  to  such  information  in the  Registration
Statement, including (but not limited to) any addition or deletion of a managing
underwriter;  (2) that for the purpose of  determining  any liability  under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such  securities at that time shall be deemed to be the initial bona
fide  offering  thereof;  and (3) to  remove  from  registration  by  means of a
post-effective  amendment any of the securities  being  registered  which remain
unsold at the termination of the offering.

     The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  Annual  Report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     The  undersigned  Registrant  hereby  undertakes  to deliver or cause to be
delivered with the prospectus,  to each person to whom the prospectus is sent or
given,  the latest annual  report to security  holders that is  incorporated  by
reference  in  the  prospectus  and  furnished   pursuant  to  and  meeting  the
requirements  of Rule 14a-3 or Rule 14c-3 under the  Securities  Exchange Act of
1934;  and,  where  interim  financial  information  required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus,  to deliver, or
cause to be delivered,  to each person to whom the  prospectus is sent or given,
the latest  quarterly  report that is specifically  incorporated by reference in
the prospectus to provide such interim financial information.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
registrant pursuant to the Registrant's Articles of Incorporation, or otherwise,


                                  Page 28 of 33

<PAGE>


the  Registrant  has been  advised  that in the  opinion of the  Securities  and
Exchange  Commission such  indemnification is against public policy as expressed
in the Act and is,  therefore,  unenforceable.  In the  event  that a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  Registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

Re:  Medical Dynamics, Inc.
     Registration Statement on Form S-3
     Registration No. 333-63901

Ladies and Gentlemen:

     In  connection  with  the  above-captioned   Registration   Statement  (the
"Registration   Statement")  filed  by  Medical   Dynamics,   Inc.,  a  Colorado
corporation  (the  "Company"),  with  the  Securities  and  Exchange  Commission
pursuant to the  Securities  Act of 1933, as amended (the "Act"),  and the rules
and  regulations  thereunder  as amended  through the date hereof,  we have been
requested to render our opinion as to the legality of:

     i) Up to 800,000 Shares of the Company's  common stock (the "Common Stock")
     which are issuable as a result of the conversion of convertible  debentures
     in the aggregate  principal amount of $1,500,000 (the  "Debentures") on the
     terms and conditions stated in the Debentures (the "Conversion Shares");

     ii) Up to 311,467  Shares of Common  Stock which are issuable in payment of
     interest  on the  Debentures  to be  calculated  as provided  therein  (the
     "Interest Shares"); and

     iii) Up to 150,000  shares  issuable  on  exercise of a warrant to purchase
     Common Stock as provided therein (the "Warrant Shares").

     The  Conversion  Shares,  the  Interest  Shares and the Warrant  Shares are
hereinafter collectively referred to as the "Securities".

     In connection  with this opinion,  we have  examined  originals,  or copies
certified or otherwise  identified to our satisfaction,  of (i) the Registration
Statement (including all amendments thereto); (ii) the Articles of Incorporation
and the By-laws of the Company,  each as amended to date;  and (iii)  records of
certain of the  Company's  proceedings  relating  to,  among other  things,  the
issuance  and sale of the  Securities.  In  addition,  we have made  such  other
examinations  of law and  facts as we  considered  necessary  in order to form a
basis for the opinions hereunder expressed.

     In our  examination of the aforesaid  documents,  we have assumed,  without
independent investigation, the genuineness of all signatures, the enforceability
of the  documents  against  each  party  thereto  other  than the  Company,  the
authenticity  of all documents  submitted to us as originals,  the conformity to
the  original  documents  of  all  documents   submitted  to  us  as  certified,
photostatic,  reproduced or conformed copies of validly  existing  agreements or
other  documents,  the  authenticity of all such latter  documents and the legal
capacity of all  individuals  who have  executed  any of the  documents  we have
reviewed.

     In  expressing  the  opinions  set  forth  herein,   we  have  relied  upon
representations  as to factual matters  contained in certificates of officers of
the Company.

     Based upon the foregoing,  and subject to the  assumptions,  exceptions and
qualifications  set forth  herein,  we are of the  opinion  that the  Conversion
Shares,  the Interest  Shares,  and the Warrant Shares have been duly authorized
and when the Conversion  Shares and the Interest Shares are issued and delivered
in accordance with the terms of the Debenture, and the Warrant Shares are issued
and delivered in accordance  with the terms of the Warrant,  the Securities will
be legally issued, fully paid and nonassessable.

     The  foregoing  opinions  are limited to the laws of the State of Colorado.
Our  opinion  is  rendered  only  with  respect  to the  laws,  and  the  rules,
regulations and orders thereunder, which are currently in effect.

     We hereby  consent  to the  filing of this  opinion  as an  Exhibit  to the
Registration  Statement  and to the  reference  to us under the  heading  "Legal
Matters" in the Prospectus. In giving such consent, we do not thereby admit that
we are in the category of persons whose  consent is required  under Section 7 of
the Act.

                                              Very truly yours,


                                              Norton * Lidstone, LLC
