Zimmer Hip Implant Failure

Hip Implant Failure

Suspension of Zimmer Durom Cup sales was driven by device failure in a significant percentage of patients. This has led to a growing number of these patients to file a Zimmer Hip replacement lawsuit. One of the most common Zimmer hip replacement problems is a failure of the device to adhere and attach properly to the hip bone.

The Zimmer Durom cup component is a one-piece design made of cobalt chromium alloy. The surface of the alloy is covered with a plasma coating. This porous coating should encourage and allow the hip bone to grow into the surface of the device, in effect, cementing the Zimmer Durom cup into place through a natural, bone growth process.  When this process fails, recipients may experience Zimmer hip implant loosening, an early indication that the device will not work properly.

With hip implants and components, there are two common types: cemented and non-cemented implants. The Zimmer hip component required no cement or any other attachment method and was supposed to secure the device to a patient’s hip bone through the natural bone growth process.

Sales of Zimmer Durom Cups suspended after 12,000 hip replacements

Between 2006 and 2008, approximately 12,000 Americans received Zimmer Hip replacements with Durom cups as part of their hip replacement surgery. The product had been in use in Europe prior to 2006, and American orthopedic specialists heard glowing reports of the hip component’s success in European patients. Shortly after the product was introduced in the United States, Zimmer hip replacement problems began to develop; complaints of excruciating pain in the hip area and lower back began to be reported. As more patients returned to their surgeons complaining of terrible pain, and severely decreased mobility, doctors became alarmed.

Zimmer Hip replacement problems increase

Some recipients of the defective Zimmer hip components lived with daily, unrelenting pain for extended periods of time before their orthopedic surgeon realized that a problem existed and took steps to end their patient’s medical nightmare. During required Zimmer Hip revision surgeries, the cause of patient’s ongoing and extreme pain was quickly discovered. Instead of attaching firmly to the hip bone as promised, Zimmer Durom cups were still loose, displaying no new bone growth or attachment; most simply fell out the hip socket when the surgery site was reopened. By some estimates more than 3000 patients experienced a complete failure of the Zimmer Durom cup to bond with bone.

Despite the complaints, Zimmer stands by the efficacy and safety record of its product and continues to offer the Durom Cup to consumers.
