Kershaw|Talley LLP understands individuals implanted with the DePuy Pinnacle are legitimately concerned about the various side effects associated with these devices.
Metallosis is one major side effect. Metallosis is the accumulation of metal debris in the soft tissues of the body. Symptoms of metallosis include metal toxicity, bone deterioration, pain, swelling and inflammation, pseudotumors (fluid-filled collection within periprosthetic tissues), and loosening, dislocation or fracture of the implant. Metal joint implants, such as the DePuy Pinnacle, significantly increased the incidence of metallosis in the last 40 years. Metallosis may involve hip, knee, shoulder, elbow or wrist joint replacements.
Metal toxicity (cobalt-chromium toxicity) is another common side effect. Metal toxicity occurs when metal components of the hip implant grind together and release metal particles into the blood stream. There is potential for long term health problems associated with metal toxicity. Blood metal analysis tests for elevated blood levels of cobalt and chromium. Individuals with the DePuy Pinnacle should request ongoing, consistent monitoring of their blood metal levels.
Side effects from metal toxicity include:
We recommend anyone implanted with the DePuy Pinnacle undergo a MARS MRI, or a
Metal Artifact Reduction Sequence MRI. A MARS MRI is an imaging technique which minimizes metal artifact (i.e. parts of the implant) while maintaining image quality. It is utilized to detect adverse local tissue reactions (ALTRs) and adverse reaction to metal debris (ARMD). Mayo Clinic describes ARMD as, "Implant-specific local and systemic adverse effects related to sensitivity to the metal or due to the wear of the metal surfaces themselves...serum chromium and cobalt concentrations correlate with ARMD."
Side effects from adverse reaction to metal debris (ARMD) include:
On Monday, September 8th, Polly Cary, Product Director of Marketing, took the stand via video deposition. Matt Reimink, a manager of the hip project division group, followed with his video deposition which continued on Tuesday, September 9th.
September 9th also included Paul Berman, former Marketing Director of DePuy, provided his deposition via video and Dr.Thomas Schmalzried who took the stand in the afternoon. Dr.Schmalzried is an orthopedic design surgeon who entered a consulting agreement with DePuy in 1996.
Dr. Schmalzried’s testimony continued throughout the day on Wednesday, September 10th. The first portion of Mark Lanier’s examination of Dr. Scmalzried ended on September 10th. Schmalzried has not been dismissed as a witness, and he will return to trial at a later time in order for Lanier to complete his examination. The defense will then begin their examination of Schmalzried.
The jury viewed Dr. Antoni Nargol’s video deposition on Thursday, September 11th. Dr. Nargol is an orthopedic surgeon, specializing in hip surgery, from England. His testimony occupied the entire day.
Tuesday, September 2, 2014 marked the first bellwether trial regarding the Johnson & Johnson (J&J) DePuy Pinnacle metal on metal hip implant.
Jury selection occurred on September 2nd. The trial proceeded with a nine member jury composed of five women and four men, including an attorney and a PhD pharmacist. Mark Lanier is the lead plaintiff’s attorney.
On Wednesday, September 3, opening statements occupied the morning. In the afternoon, Andrew Ekdahl, ex-DePuy President, took the stand. He was head of marketing during key periods in question. Currently, he is chairman of DePuy Synthes unit’s global orthopedic business. Ekdahl implies this is a promotion from his previous position. His testimony monopolized all of Wednesday afternoon as well as Thursday, September 4. Trial is not held on Fridays.
