The Maxera Cup: The Cure to Zimmer Hip Side Effects?

Staff Writer | June 3rd, 2011

On June 1, Zimmer Inc. announced the introduction of the Maxera Cup, a hip replacement component that may serve to replace an earlier model that has been implicated in a high rate of Zimmer hip side effects.

The Maxera Cup, which fits into the acetabulum or hip bone, claims to offer increased range of motion and little or no Zimmer hip metallosis, which occurs when orthopedic components abrade, shedding toxic metal particles into the blood stream.

Currently, the Maxera Cup is only available in Europe, the Middle East and Africa (EMEA), though it may soon be cleared for use in the United States.

New implant product to prevent Zimmer hip side effects

The Maxera Cup may supplant an older acetabular hip component made by Zimmer called the Durom Cup. In 2008, the Durom Cup was involved in a temporary Zimmer hip recall after concerns were raised about the fixative surface of the component. A number of Zimmer hip lawsuits are currently proceeding in New Jersey over the Durom Cup.

While the Maxera and the Durom Cup utilize the same fixative coating, which is called Ti-VPS (titanium vacuum plasma spray), the Maxera is a larger device with a greater surface area, and thus it may offer more support and fewer Zimmer hip side effects than the Durom Cup.

Maxera less likely to cause Zimmer hip metallosis symptoms

More so, the Maxera is a ceramic-on-ceramic device as opposed to the Durom Cup, which is a metal-on-metal hip replacement system. Ceramic-on-ceramic is less likely to cause Zimmer hip metallosis than other metal-on-metal systems, which are currently under high scrutiny by the FDA.

In May, the FDA ordered that Zimmer and 20 other orthopedic device manufacturers conduct safety studies on metal-on-metal hip replacement systems, which have been implanted into million of Americans. The FDA order follows a massive August hip recall involving DePuy Orthopaedic’s ASR replacement system, which has been implicated in revision rates as high as 49 percent over six years.

So far, Zimmer’s temporary Zimmer hip recall of 2008 has cost the company hundreds of millions of dollars. The company has set aside nearly $150 million to compensate Durom Cup recipients for Zimmer hip side effects. It is unclear how much of that settlement fund has already been paid out to Durom Cup recipients.
