DePuy Hip Replacement Surgery

DePuy hip replacement orthopedic implant is a multi-component device designed to replace the femoral head, as it fits into the acetabular socket of the pelvis. Implants manufactured prior to July of 2003 are known to cause unforeseen side effects in the implant region of the pelvis, often involving swelling, chronic pain and immobility, as the components fall out of alignment.

The FDA initially approved the two-part system, but discovered later that Johnson & Johnson, the parent company of DePuy, relied on some test data that did not include revisions to the components. Although the FDA approved the orthopedic device, it does not remove Johnson & Johnson or its subsidiary manufacturers from liability for injuries to patients. Because of the FDA warnings about possible injuries and complications leading to a high number of revision surgeries, DePuy has offered to pay for revision surgery for patients who received the defective implant.


Wright Medical Technology manufactures a hip replacement component system that utilizes a long stem component designed to be implanted into the femur, while supporting the ball component that is supposed to fit snuggly into the acetabular socket of the pelvis. Because of the unique stem-and-ball configuration, the device is supposed to give orthopedic surgeons a wider range of options for making the connection between femur and pelvis at the correct angle for the individual patient’s needs. Unfortunately, it has been estimated that more than 11 percent of the devices fail after a period of recovery and rehabilitation, owing either to the stem failure in the femur or improper alignment. The resulting side effects include swelling, chronic pain and misalignment of the pelvis.


Zimmer NexGen CR-Flex implants are among the leading orthopedic devices used for total knee replacements surgical procedures in the United States every year. Although the part received FDA approval, several patients who have received the implants have indicated severe swelling, pain and immobility, resulting from the device failing to properly bond with the surrounding bone and body tissue over a lengthy period of time. Consequently, national lawsuits may be filed, as more information becomes available to determine whether the NexGen orthopedic device is medically defective.


The Zimmer Durom hip cup orthopedic implant is intended to act as a bond between the hip socket and pelvic bone. The shell of the device is porous, allowing the patient’s bone to grow and fuse naturally with the device, without the use of screws or surgical epoxy. Despite FDA approval, however, patients receiving the implants manufactured between 2006 and 2008 have reported a high amount of pain and discomfort, well after the expected recovery and rehabilitation period. The manufacturer admits that the devices manufactured between those years may fail to fuse properly with the bone. To remedy the medical problems, Zimmer Durom has issued a ‘recall’ to offer revision surgery for patients who have experienced injuries and painful side effects and injuries.
