According to reports, the Food & Drug Administration (FDA) recalled yet another metal-on-metal (MoM) hip implant. The Zimmer Trabecular Metal Modular Acetabular System was recalled on September 27, 2011. The Zimmer hip recall is the latest in a string of strong indications that MoM hip implants pose a serious risk to patients.

The Zimmer hip implant in question replaces hip sockets in total hip arthroplasty operations. The device is made of a shell, a locking ring, and a line. The hip implant may come with optional screws. Reports indicate that the locking ring groove is not appropriately deep. The inappropriate groove depth may prevent the liner from fitting into the shell.

The Zimmer hip replacement recall is not the only ongoing MoM hip replacement recall. In August 2010, Johnson & Johnson subsidiary DePuy Orthopaedics recalled two MoM hip replacement models: the ASR XL Acetabular Hip System and the DePuy ASR Hip Resurfacing System. Johnson & Johnson recalled the MoM hip implants after medical researchers found an abnormally high failure rate for the devices. Zimmer launched a Durom Cup recall as well.

Hip replacement failure may be a horrifying occurrence for a patient. The hip replacements are surgically implanted into the patient's body. Any defects in a MoM in a hip implant may result in serious pain for the patient. For example, DePuy defective hip patients report pain resulting from the grinding of the metal parts of the implant. Patients have also reported difficulty walking.

The FDA has received thousands of complaints from MoM hip implant patients. According to national news agencies, the FDA has received more MoM implant complaints in the past year than in the previous four years combine. Patients who have received a MoM hip implant from Zimmer or DePuy would be advised to contact a skilled hip recall lawyer to learn about their legal rights.
