Wright Medical Group’s Medical PROFEMUR Z Hip Replacement System is another hip replacement in the long line of defective metal-on-metal hip devices that have been used on thousands of Americans.

Approved Uses of the Drug

The Wright Medical PROFEMUR Z Hip Replacement System, was approved by the FDA for only total hip arthroplasty (replacement or resurfacing). However, like the hip replacement systems created by Stryker and other medical device companies, the PROFEMUR Z System has significant design defects. These design defects result in the hip replacement system failing much earlier than its projected “life span.”

Not only have patients found the hip implant has the tendency to come lose or break or the implant fails entirely, the PROFEMUR Z Stem implant was found to cause debilitating hip pain, joint swelling, altered gait, and eventually the inability to stand or walk. After initially receiving the implant, patients have found it quickly corrodes and “frets” or rubs together to cause damages. These design defects have resulted in patients having to endure multiple hip revision surgeries. In fact, the Australian National Joint Registry found that 1 in 9 patients who received the PROFEMUR Z Stem implant had to receive revision surgery because the hip implant failed.

Device Increases Risk of Metallosis and Other Problems

As with other metal-on-metal hip replacement devices, patients have found the metal deteriorates or flakes off and it results in metallic debris entering the body, specifically the bloodstream. Also known as metallosis, metal in the blood can cause serious problems to the heart, kidney, and other organs. Patients receiving the PROFEMUR Z Stem would find themselves suffering from shortness of breath, vision problems, and numbness. Recipients of this hip replacement system have also suffered from local tissue reactions such as pseudotumors and aseptic lymphocytic vasculitis-associated lesions.

The design defect can be found in the PROFEMUR Z Stem system’s modular femoral neck. The modular neck stem is the portion of the implant that fits into the thigh bone (femur) to anchor the prosthesis. This neck has the ability to be adjusted according to the patient’s leg length to allow for a more comfortable and natural fit. This modular neck was marketed to be a better option to the traditional metal ball & cup system common in older hip replacement devices. The system comes with the stem and then six interchangeable neck pieces (which come in two sizes). Unfortunately, victims of this defective product have found that the implant has a tendency to bend at the point of the femoral neck. This results in the implant failing or requiring replacement at a much faster or earlier rate.

Wright Medical Group is the Tennessee based company that has designed, created, and marketed hip replacement systems since 1950. Joint replacement medical devices constitute more than half of the company’s sales. The PROFEMUR Z Stem line, however, is not the only Wright hip device to be facing lawsuits. The CONSERVE Plus line has faced multiple lawsuits alleging similar product defect claims. Wright Medical Group was also the focus of a federal investigation in 2007 because the government found evidence the company was bribing doctors to use its products. To avoid liability and further suit from the government, Wright Medical paid approximately $7.9 million in fines.
