December 2011, Conserve Hip Systems and possible failure?
In 2009, the FDA approved the Conserve Hip Systems, made and sold by Wright Medical Technology, Inc.
Since 2009, there have been more than two hundred adverse reports where people claimed that the Conserve Hip Implant failed to do what it was promised to.
At year end, there is now a pending Petition for an MDL regarding those cases. The issues relate to the Conserve Plus Total Hip Replacement System and the Conserve Plus Resurfacing System. The total replacement system has four parts-- a metal femoral stem, metal femoral head, metal modular neck and the metal Conserve cup. The resurfacing system has two components: the metal femoral head cap and the Conserve Plus metal acetabular cup. Both systems are intended to be used as a hip-replacement implant when a patient’s hip joints are damaged or diseased as a result of fractures, osteoarthritis, rheumatoid arthritis and avascular necrosis.
The common component in both systems—and what is at the heart of the lawsuits—is the “Conserve cup”, which is a cast cobalt chromium molybdenum piece that holds the metal femoral head, mimicking the natural movement of a hip joint. It is that unlined cobalt part that is allegedly causing serious harmful effects to patients who receive the implant device. The problem is that these two metal components cause the release of metal particles around the hip joint and surrounding tissue. As a result, a high percentage of patients have developed metallosis and biologic toxicity and are experiencing a high and early failure rate of the device.
Our office is investigating people who think this product failed after implant.
