Zimmer Durom Hip Replacement Implant Lawsuit
Zimmer Durom Hip Replacement Implant
In 2008, Zimmer Holdings suspended sale of Durom Acetabular Cup following numerous complaints of a high implant failure rate. Since 2006, when Durom Cup came to be used in the United States, numerous complaints and lawsuits have been filed against Zimemr Holdings. Most of the lawsuits filed against Zimmer allege that the defendant did not disclose the risks associated with the hip implant cup when it marketed the product. However, Zimmer continues to deny the allegations, precisely blaming the surgeons for the high hip implant failure rate. Many patients have complained that the Durom Cup failed within two years of implantation, as a result of which, they had to bear severe pain and undergo a revision surgery.
Patients complain of pain and stiffness following their hip replacement surgery with Durom Cup. They allege that they experience so much stiffness and sharp pain in the groin that they cannot walk properly. Most of the patients also allege that they even find it difficult to come down the stairs.
Zimmer Durom Cup Dangers
The Durom Cup had been implanted in more than 12,000 patients in the country from 2006 to 2008. According to reports, about 11 percent of the Durom Cup implants failed in the first two years. However, Zimmer claims that the product can last for 15 years, saying that the metal hip replacement system is far more durable than traditional implants.
In fact, the Durom Cup is a metal-on-metal hip replacement system, with multiple metal components designed to fit into a “ball and socket” formation. As the ball rotates and rubs against the cup-like socket, it sometimes presses against the edge of the cup, thus generating a large volume of microscopic metal shavings into the patient’s bloodstream. The metallic debris can be absorbed by the soft tissue, resulting in
metal poisoning or metallosis. In some patients, it might even take the form of cobalt chromium poisoning, which can cause a lot of other problems for the patient, including inflammation and severe pain, tissue death, loss of surrounding bone, nausea, fatigue, memory problems, headache, vertigo, tinnnitus, and vision and hearing problems. The patient must undergo a secondary surgery to get rid of the metallic debris and toxicity. However, the risk associated with revision surgery cannot be negated.
Surgeons at leading orthopaedic centers in the country opine that revision surgeries can become extremely complex due to presence of more scar tissue and less bone, leaving some patients with lasting complications and a longer recuperation period. In fact, the secondary procedure is more difficult, painful, and complicated than the first hip replacement surgery.
Orthopedic surgeon Dr. Lawrence Dorr believes that “bad design” of the Durom Cup is responsible for a more-than-expected implant failure rate. This clearly reflects in the number of patients that have experienced hip implant failure in the country. According to estimates, more than 3,000 patients have experienced hip replacement surgery failure in the country.
Zimmer Durom Cup Design and Failure
The Durom Cup is designed to fit into the cup-shaped depression of the hip joint so that it holds the femoral head. However, reports suggest the Durom Cup does not fuse properly with the hip joint due to failure of necessary bond. Many surgeons complain that the problem lies with the fixation surface of the Durom Cup, having a plasma-sprayed titanium coating, which is actually meant to facilitate natural growth of the hip bone on the surface of the device. Zimmer Durom Cup does not have any attachment device that would hold the implant and only relies on the bony ingrowth to hold the implant and secure cup positioning. However, lack of bony ingrowth in many patients resulted in cup loosening, causing hip implant failure.
Even many surgeons claim that they did not find any natural bone growth in the patients who had to undergo revision surgeries.
Zimmer Hip Replacement Recall Lawsuit
In February 2011, the FDA warned that some "unique risks" were associated with metal-on-metal artificial hips due to the wear and tear of tiny metal ions, which can damage the nearby tissue. A number of individuals who received the Durom Cup between 2006 and 2008 have sued Zimmer Holdings for their device failure, pain and suffering, physical and emotional distress, injury, shame and humiliation, medical expenses, disability, mental anguish, memory impairment, punitive damages, loss of enjoyment in life, and inability to lead a normal life.
A number of product liability lawsuits filed against Zimmer Holdings allege that the defendant company failed to inform patients and physicians about its defective artificial hips. Earlier, Zimmer denied that the cups were defective; rather, it blamed the surgeons for the high failure rate of the cups, alleging that they found it difficult to implant the device. It advised surgeons to go for training to learn how to implant the device.
Like Zimmer, DePuy Orthopedics, too, faces similar lawsuits due to a more than expected device failure rate. St. Gobain Desmarquest, Stryker Corporation, Suzler Orthopedics also face product liability lawsuits for marketing defective hp replacement systems.
Have your blood levels checked immediately for metal or cobalt poisoning if you or any of your loved ones have had an artificial metal hip implanted.
