 TMJ device FDA approval was: Doc in the Box database re: Total TMJ device

Webmaster asked a very important question below and of course it would
be if what is pasted below from the FDA has changed since 1994. If it
has dont you think the public deserves to know?

Original Question
     What is "total joint" surgery?
Response
     Total replacement of the temporomandibular joint involves an
incision in  front of the ear for access to the socket (fossa) as well
as an  incision below  the angle of the jaw. through these 2
incisions, a metal socket (fossa) is  placed and screwed into
position, and a metal condyle is used to  replace the  bony condyle of
the mandible. It is also held in place with screws. The  only  total
TMJ prosthesis that is approved by the FDA at this time is called the
Christenson Total Joint. A second opinion consultation is usually
 recommended when a patient is contemplating total joint replacement.

From the FDA:

What questions should patients consider asking when discussing TMJ
surgery with the surgeon?

Patients should discuss with the {*filter*}surgeons the risks and benefits
before implanting any device. Presently there are two TMJ implants on
the market, the Morgan and Christensen which were on the market before
1976 prior to the enactment of the medical device law in 1976 and thus
are exempt from premarket notification. The FDA does not have safety
and effectiveness data on either of these TMJ devices. Some questions
patients may want to ask include:

 1. How long has this device been on the market?
 2. Do you have the name, manufacturer, model number and lot number of
the device?
 3. Does the labeling on the device indicate that this is a temporary
or permanent
implant?
 4. If temporary, how long is the implant intended to remain
functional?
 5. What are the possible complications of having the device
implanted?
 6. What are the advantages of having the device implanted?
 7. Are there alternatives to surgery? what are they?
 8. What are the advantages and disadvantages to the alternatives?
 9. Given my condition, am I a candidate for alternative therapies?

Let's see what the advi{*filter*}t I recieved from you really was.
And while were at it let's see what your "specialist" replied to about
the Christenson Implant. See both below.

Bruce,

Just a note to hopefully wrap up all the "fun" that you,  your
organization and your associates have had at the expense of
www.onlinedoc.com.

We can probably agree that you and Ms. Broock (also a cts.com
account...hmmmm!) found and pointed out what was a materially
insignificant mis-statement in the database at the subject site. While
you could have directly contacted the site to point out the error, you
elected to go public with it at sci.med.dentistry. You even threatened
an FDA complaint when you knew that the facts won't support one. No
problem, your right...your choice.

As soon as the mis-statement was brought to our attention, the
database was modified to accommodate your objections. You were so
advised.

I think at this point, however, it's important to point out to you,
the company that you represent, and the service providers
(NNTP-Posting-Host: changjin.cts.com) who provide your connectivity
that your postings and re-postings of rants alleging "spreading lies"
and "this bold faced attempt to defraud the public", "it's someone
taking advantage of what the public doesn't know or understand",
"truly the strangest lie I have seen lately", and "someone is
promoting a device" all fall within the clear legal definition of
defamation and libel.

There was no "lie", no "attempt to defraud", no "taking advantage",
again no "strangest lie" and "no promoting a device". You certainly
know all that. You may not be aware that such outrageous publication
of libellous material through the usegroups is not excused under the
law, and is actionable under civil statutes. I want you to be aware of
that...

I would also be amazed if such outrageous postings as you have made to
the usegroup in this matter don't constitute a gross breach of the
Acceptable Use Guidelines to which cts.com might expect user
adherence. I know that they are in breach of the FAQs on usegroups.

I am not so naive as to assume that your daily pious posturings,
hysteria and sanctimonious buffoonery in this matter are not without
an (as yet) unidentified measure of self-interest. Please accept this
post in the spirit in which it is intended...as a clear caution to you
and your sense of self-interest that you should cease and desist from
publishing or promoting further defamation and libel against
www.onlinedoc.com, Doc In The Box and the Board Certified
Professionals associated with that site, at risk of legal action which
could involve both you and your service providers.

Thank you for your cooperation.

John D. Buquoi

Subject: TMJ prosthesis

Dear Rob,

The TMJ Fossa-Eminence and TMJ Condylar Prostheses manufactured by TMJ
Implants, Inc. (the "Company"), are legally marketed in compliance
with the Federal Food, Drug, and Cosmetic Act ("FDC Act") for use in
the partial and total reconstruction of temporomandibular joint
disorders.

The Fossa-Eminence and condylar Prostheses have been in commercial
distribution in the United States in their present form for both
partial and total TMJ reconstruction since prior to May 28, 1976, the
enactment date of the 1976 Medical Device Amendments to the FDC Act.
The prostheses have been used both individually (Fossa-Eminence or
Condylar) as a partial TMJ prosthesis and together (Fossa-Eminence and
Condyle) as a total TMJ prosthesis siince their introduction in 1961
and 1965, respectively.  As "preamendment" devices, the prostheses are
exempt from the premarket notificaation requirements under section
510(k) of the FDC Act. Accordingly, as long as the Fossa-Eminence and
Condylar Prostheses are not significantly changed or  modified in any
fashion they can continue to be legally marketed without prior FDA
premarket clearance or approval.

The Preamendment status of the company's prostheses for partial and
total TMJ reconstruction was confirmed by the cooking.net">food and Drug
Administration ("FDA") in 1992 in response to the company's request
for such determination.  The letter states:

Quote:
>        We (FDA) have determined that the records and affidavits which you
>        (TMJ Implants, Inc.) have submitted for our review are sufficient
>        to support the preamendment status for the Fossa-Eminence and
>        Condylar Prostheses.  Premarket notification would not be required
>        for these devices to continue to be marketed, providing they were the  
>        same devices, with the same intended use, manufactured according to
>       the processes as those used on or before May 28, 1976.

The above letter is from Ronald M. Johnson, Director, Office of
Compliance and Surveillance, Center for Devices and Radiological
Health, to Dr. Robert Christensen, President, TMJ Implants, Inc. (Dec.
2, 1992)

In addition, the company submitted and obtained FDA marketing
clearance of two separate 510(k) notifications for the Fossa-Eminence
and condylar Prostheses on October 25, 1993 and April 21, 1994,
respectively for sterile versions of the devices.

The 510(k) notification "clearance" procedure allows FDA to find that
a medical device is substantially equivalent to a legally marketed
predicate device.  This determination results in a classification of
the device and permits the device to be legally marketed in the same
manner as the predicate device.  "Clearance" of a 510(k) notification
does not mean that the FDA "approves" the device on the basis of
clinical evidence of safety and effectiveness.  In the case of the
sterile Fossa-Eminence and Condylar Prostheses, FDA determined that
these devices were substantially equivalent to the non-sterile devices
that were in commercial distribution prior to the enactment of the
Medical Device Amendments of 1976, and, therefore, could be
legally marketed in the United States.

Finally, FDA has issued a proposed rule to classify certain TMJ
implants as class III medical devices and require submission of
premarket approval ("PMA") appplications for such devices.  However,
submission of PMA applications cannot be required by FDA prior to 30
months following issuance of a final classification regulation.  Until
such time, the Fossa-Eminence and Condylar Prostheses can be legally
marketed in full compliance with the FDC Act.

In summary, when distributed as non-sterile or sterile devices, the
Fossa-Eminence and condylar Prostheses are legally marketed in full
compliance with the FDC Act for use in partial or total reconstruction
of TMJ disorders.  For further information the FAX # of TMJ Implants,
Inc. is 303-277-1421.

As to the "approval" of these prostheses by the FDA, they are
certainly approved for marketing and distribution in full compliance
with FDA and FDC regulations.  They are indeed different than the
total joint prostheses that were marketed and distributed by the Vitek
Company, and all of us as {*filter*}& Maxillo{*filter*} Surgeons will be forced
to live the rest of our practice careers with that unfortunate legacy.

Living the rest of their practice careers with that unfortunate legacy
(Vitek, Inc. TMJ implants) may well be a sorrow of the {*filter*}&
Maxillo{*filter*} Surgeons.    

But, it should be pointed out that the patients are the only ones who will
be "living" with this unfortunate legacy... and for the rest of their
lives.   I have nothing else to say.

Webmaster,
  I, like thousands of others, live daily from morning till night, with
this unfortunate legacy that the Vitek disaster has created!  Thanks for
reminding others of this unfortunate situation!  I understand that {*filter*}
surgeons will have to live down the legacy that this has created, but, the
individual patients are the true victims.  I'm sure that all {*filter*}surgeons
recognize this fact, also!
Pat

Dont try and sell us your dog and pony show. The simple fact is you
got caught. I would never show my face back around here either if I
had as much egg on my mug as you have.

Of course I just shutter at the thoughts of your army of lawyers
descending upon me and my comrades, lets see, how'd you put it??
