Personal Note from the Baroness:  I have lived through every minute of this timeline.  obviously not always aware of the goings on behind the scenes. Such as what was known prior to my first surgery for the implantation of the Proplast’s. I went through a period of real anger. Anger at my country, anger at my doctors, and anger at myself. I was part of the first class action litigation and received some settlement monies. There is not enough monies that could ever reimburse me for the damages. And that is all that can be reimbursed for. Sure pain is part of the damages, but how much is every day, every hour pain worth?

Vitek the company and the man who owned Dr Charles Homsey who manufactured the implants after final FDA approval filed bankruptcy immediately upon hearing through the medical an d dental community that the implants were failing. he filed both corporate and personal bankruptcy from another country. Switzerland.

The most surreal thing is I am grateful I accepted the settlement monies and did not try to hold out for a trial and more damages awarded. Of which I also signed a confidential clause stating I would not divulge my awards. I filed my Torte suit in 1992, the first offer of settlement came in 1994. The others just as slow if not slower. Had I gone to trial I would still be waiting now.

Why not go to trial? First you and your attorney’s must find a court that will hear a summary motion. In this motion we asked the court to agree with us, the plaintiffs,  we, were in fact damaged by those we were suing. There were many agency’s involved from hospitals, to universities, to private businesses with public stock holders. In the cases against DuPont and Dow Corning amazingly the judge found that we ,the plaintiffs, did not have standing (cause) to sue the two monster companies DuPont & Dow Corning. (makes me very suspicious still today as these two corporations have a big lobbying industry on Capitol Hill.)I was once again grateful I had decided the trial would be too much and took the settlement.

DuPont and Dow Corning Settle With Some Plaintiffs.

The courts however took pity on some of the plaintiffs by offering miniscule settlements if we would just agree to go away. The two Biggies knew that they would no doubt succeed, but the time and money wrapped up in the litigation  and not to mention the media attention inspired them to offer what is known in the litigation industry as nuisance settlements. I promise you it did not even come close to enough to live on for one year for a family of four. I lost my employment and income because i was unable to work which meant I also lost my profit-sharing. I also had to stop going to school to complete my degree, which I had waited to go back to once my children were in school full-time to complete my degree. This was severely a detriment to myself as well as my family.

What was painful to my spirit was that  I could no longer sing like I had all my life.It had become impossible to open my mouth more than 3 cm on my good days because of the damage to my TM joints.  Think holding a note as one example where you need to be able to have full range of motion of the mouth as just one example. Not to mention how this type of disease in the TM joints also affect a persons hearing. Mine was already compromised from live music speakers I did not need anymore help.

these assaults by medical devices are not the first of their kind. Nor will they be the last. I recall in horror what the IUD devices did to so many women of my generation. And now we are dealing with Hip & Knee Joint replacement Implants being recalled.

I just wonder when we will ever learn.

There has to be a better way. This cannot be rocket science, can it?

Please feel free to contact me if you have any questions or comments. And thank you so much for taking the time to become familiar what this business is all about.

  1. We have very little recall against doctors in our country. Glad you got some money – cannot compensate you for the pain and misery you have been through. It would have been “nice” if we could have received compensation for the doctor error with Vic. It would have helped keep her comfortable i.e. pain control, nursing etc.

  2. I really don’t know a country where doctors are held accountable Its disgusting what can be done in the name of medicine.
    I’d love to write a tell all book about cases like Vic’s and mine. Although very different its the fact that we put our lives and trust in them and to what end? In Vic;s case to much an end. it rather makes me very angry! Sorry tersia, it is emotional and then I read what is going on with Vic an your life….. God’s blessing my friend ~

  3. Dear Baroness, I am also a victim of the Vitek implant and like you and all the others have a lifetime of pain and health issues to carry. Every story I read makes me cry and reminds me how much the inventors/doctors/developers of medical devices who do not care about patients only money are destroying peoples lives. I also fault the legal system that allows people like Dr. Homsey to hide out and live their lives instead of facing their, I wont say mistake, because he knew in the end what he was doing and didnt stop, wrong doing and the big companies who have millions of dollars to hide behind. Its a sad day all the way around when the injured and wronged have to defend themselves rather than the ones that have injured and wronged them. I still feel all of those involved in this mess should be held accountable but it will take a movement by the masses for the rules to change in the favor of the one. You will find some interesting reading on the FDA website if you look up Proplast that Dr, Homsey used in his implant. My prayers are with you and with all who have had to go through this horrible nightmare.

  4. I to had the Dow Corning Silastic implant inserted while active duty n the Air Force. It was inserted in 1985 and was abruptly removed 6 month later, stating it was a “temporary” implant. Since that time I had several procedures and ended up with severe bilateral tmj. I was discharged from the air Force after 12 years of service for Tmj. Since then (1992) I have experienced constant pain, but in 2008, my pain became debilitating on the side the implant was inserted. I failed to mention after the implant was removed it was broken and had a hole in it. I then started a roller coaster of getting block injections 2-4 times a week to numb the pain. I have had condylotomies on both tmj, and the right side had a second take dow condylotomy. It did not help! I eventually asked the Dr. to remove the condyle. She did. She is the one who informed me of the recall of the implant. I was never notified. She said my joint is completely gone. Nothing but foriegn body reaction and scar tissue. My left joint has begun to fail and at this time my bottom jaw has receded causing me to have difficulty swallowing, choking and my tongue does not know were to go anymore. I feel as if my tongue is enlarging and taking over what area I have been left with. I am a RN and quit working in 2010. I am on pain management, taking strong narcotics daily. This keeps my pain level at 6-7. I still get nerve blocks quite frquently. I no longer Drive, I have lost 50 lbs over a 2year period. My appetite is poor and I drink most of my meals. My opens to 8 mm and on a good 11 mm. I am 57 y/o. I am fortunate my Veterans benefits help with my monthly living expenses. I filed for Social Security, but they said although I could not do work as a RN, I could work as a janitor.(How I am suppose to do this while taking strong narcotics, I do not know)! So, I missed out on the Lawsuit against Dow Corning. Luckily the Veterans administration is compensating me for my loss. So please anyone who reads this, Do Not Have Surgery. It will worsen your pain and may cause more problems down the road. Thank you for letting me vent. For all you TMJ sufferes God Bless!
