Zimmer Hip Replacement Lawsuits
Hip replacement patients who received the Zimmer Durom Cup have filed lawsuits after experiencing excruciating pain and failure of the implant.Zimmer Durom Cup Hip Replacement has a High Rate of Failure
The Zimmer Durom Cup is a metal on metal (MoM) hip replacement implant device consisting of a metal acetabular cup or socket implanted in the pelvis in which the metal femoral head or ball of a corresponding implant on the femur moves, allowing flexibility of the artificial hip joint. Zimmer Holdings, Inc. designed the Durom Cup to bond with new bone growth in the patient’s hip socket instead of attaching with screws, cement or epoxy. However, the device has a high rate of failure to bond that requires corrective surgery.After reviewing more than 3,000 reports of problems with the Zimmer Durom Cup in less than two years on the market, Zimmer Holdings, Inc. blamed the failures on the inadequate skills by surgeons performing the hip replacement procedure and decided to pull it from the market until they could provide the proper training. Doctors found that patients in Europe did not have the same high failure rate with the Zimmer Durom Cup as patients in the U.S., but the U.S. version of the device has a different surface coating than the European product.
Dr. Lawrence Dorr, a prominent orthopedic surgeon in Los Angeles, CA, wrote a letter to the American Association of Hip and Knee Surgeons reporting that some of his hip replacement patients were having problems with the Zimmer Durom Cup. He expressed concern about the fixation surface of the cup and a circular cutting surface on the periphery of the cup he believed prevents the cup from fully seating and bonding with the bone.

In addition to bonding problems, the movement of the metal ball in the metal socket of MoM hip replacement implants generates metal shavings, called debris, at the implant site that embeds in the soft tissue and causes severe pain, inflammation, permanent tissue damage, disability and the complication of future surgeries. MoM implants also release metal ions into the body.
