DePuy Pinnacle Trial Status (Week 7 10/13-10/16)

Monday, October 13th was Columbus Day and the courts were closed.

On Tuesday, October 14th, the defendants called Dr. Roger Emerson, an Orthopedic Independent Medical Examiner, to the stand.

Dr. Emerson returned to the stand on Wednesday, October 15th. His testimony was followed by Dr. Math, an orthopedic radiologist.

Andrew Ekdahl, the ex-president of Johnson & Johnson’s DePuy unit, returned to the stand via video deposition on Thursday, October 16th. He was followed by Dr. Lisa Pruitt, defense witness, and a mechanical and biomedical engineer who teaches at the University of California, Berkeley. Her testimony will resume Monday, October 20th.

Metal-on-Metal Hip Implants and Revision Surgery


Patients undergo hip replacement surgery in order to improve their quality of life. Hip replacement surgery is supposed to increase activity levels, improve range of motion, and ease pain and suffering. Unfortunately, after their index (initial) surgeries, individuals soon find their hip replacement is hindering rather than helping. This is often the case with metal-on-metal hip replacements.

Metal-on-metal hip systems such as the DePuy PinnacleDePuy ASRStryker Rejuvenate, Stryker ABG IIStryker AccoladeWright Pro Femur and Wright Conserve, have the highest failure rate compared to any other hip implant. Most individuals experience serious complications and subsequent failure with these implants. Complications from metal-on-metal hips include cobalt-chromium toxicity, metallosis, pseudotumors, infection, loosening and implant wear, joint stiffness, and fracture. These complications cause implant failure. Implant failure requires a second surgery, known as a revision surgery. A revision surgery requires removing the failed implant(s) and replacing with a new device.

Revision surgery is more complex and risky than the index surgery because it is more invasive. Therefore, the risk of complications is greater with a revision surgery than initial surgery. The implants are more likely to loosen, migrate, and fracture since the bone and hip joint are severely manipulated from the previous implant.

Hip Surgery: The Importance of Doctor-Patient Communication


An open and honest dialogue with your doctor before surgery contributes to better outcomes. This means providing your physician with a comprehensive medical, surgical, and social history. This also ensures the doctor gives you the best care in creating a plan that fits your specific needs. Before any surgery, it is essential to voice any questions or concerns you might have.

The American Academy of Orthopedic Surgeons (AAOS) created a list of questions which may help in discussions with your doctor:

  • What are your experiences with specific hip implant devices and how often do you use one over the other?
  • What are the risks and benefits of different devices (metal-on-metal, metal-on-polyethylene, ceramic-on-polyethylene, and ceramic-on-ceramic devices)?
  • If applicable, what is the surgeon’s personal experience and outcomes with the respective devices?
  • If your surgeon recommends a certain device, ask why that hip implant is the best for your situation.
  • What are the major and/or most frequent complications of surgery?
  • Is the skill and experience of the orthopaedic surgeon more important than the device or procedure?
  • Can you give me any information on outcomes and complication rates?
  • If I do not have surgery, what is the risk?
  • How much pain can I expect, and how will it be managed in the hospital and after I go home?
  • How long will the device last, and what can I do to make it last as long as possible?
  • What are the pros and cons of minimally invasive (mini-incision) surgery? Does it really make a meaningful difference in the result, or does it pose unnecessary risks?
  • What will I be able to do/not do after my total joint replacement?
  • Is therapy necessary after surgery?
  • How long will I be in the hospital?
  • Will I be able to contact you after the surgery if I have a question or problem?

Is your DePuy Pinnacle harming you?


People might think because the DePuy Pinnacle is not recalled it may not be harmful. This is false!  

The DePuy Pinnacle is a metal on metal hip replacement system: the ball and socket of the device are made of metal. Nowadays, the words “metal on metal” are enough to trigger a worried response from individuals implanted with these types of hips. And rightfully so.

With metal on metal implants, like the DePuy Pinnacle, the metal ball and metal socket rub against each other during activities. Metal is also released from implant parts where two components connect. Metal release results in metal ions to wear off the device causing damage to bone and soft tissue surrounding the implant and joint. This is known as an adverse local tissue reaction or adverse reaction to metal debris.

Adverse reaction to metal debris can cause pain, device failure, and implant loosening which may lead to needing a revision surgery. When metal ions are released into the bloodstream, it can precipitate a systemic reaction and cause other issues including skin rash, cardiomyopathy (a heart condition), neurological impairment, psychological changes, and thyroid abnormalities. The long term effects of exposure to these metal devices is unknown.

We highly recommend you speak to a doctor immediately if you have a DePuy Pinnacle whether or not you are experiencing the aforementioned symptoms. 

DePuy Pinnacle Trial Update: Week 6 10/6-10/9



We are providing an update on the ongoing DePuy Pinnacle trial now pending in federal court in Dallas, Texas. This is the very first case to be tried in front of a jury in the country. There are about 6,000 cases now pending against DePuy by people who were injured by their Pinnacle hips. We are now in the sixth week of the trial.

This week in the trial we continued with the defense case and the witnesses DePuy is putting on the stand. They introduced a series of expert witnesses to talk about all of the things DePuy did to test and get the Pinnacle hip approved by the FDA. The purpose of the testimony is to give jurors the impression that DePuy is a responsible company, and that they performed all the appropriate tests the FDA required, and really didn’t do anything wrong. There is a problem with that argument. The way the FDA works is unique. A lot of people believe when the FDA approves a product, they thoroughly investigated the product and decided that it’s a good product, it’s safe, and the warnings are adequate. The truth is something different. With medical devices, such as hips, manufacturers are not required to test the device. They can get approval from the FDA to sell the device with almost no testing at all if they show the device is substantially similar to another design that is already on the market. The issue with whether FDA approval means the device is safer, or the company did the right thing, really doesn’t mesh. So, when the FDA approves a device, they are not saying they tested it. The FDA doesn’t really test devices. The FDA relies on manufacturers to test the devices, and the manufacturers tell the FDA they tested the device. That’s when the FDA approves the device.

DePuy is trying to create the impression that because this was FDA approved it was a safe device and their testing was appropriate. In reality, this isn’t true.

The next phase of the trial will be the plaintiff’s rebuttal witnesses, present witnesses to rebut the arguments the defendants have made.
