Stryker Rejuvenate Design

Stryker Hip Implants

Searcy Denney Scarola Barnhart & Shipley PA has been a leader in groundbreaking litigation involving the Stryker hip replacement recall and our lawyers were the first to file Stryker hip implant lawsuits. If you have suffered metal poisoning from hip replacement or other Stryker hip replacement problems, contact us today to discuss your case.

Stryker Hip Implants Designed to Be Used With Different Components

The Stryker Rejuvenate System is made up of a stem and neck design. The biggest draw of this new design was the modular neck. While most hip implants have only two moving parts, the Stryker Rejuvenate System relied on four moving parts, including the femoral stem, metal neck, acetabular cup and ball.

The Rejuvenate line was designed to be used with any currently available Howmedica Osteonics acetabular components, including cobalt chromium femoral heads and ceramic femoral heads. In 2009, Stryker received marketing approval for a size extension of the combined head and neck length options available in the Rejuvenate line. Because the device offers a variety of sizes for each part, a surgeon can determine which components are best suited to meet the individual patient’s needs. Through the ability to combine size variations, surgeons were able to manage the leg length, neck version and femoral offset of virtually any patient.

Regulatory and Design History of Stryker Hip Implants

Stryker (a division of Howmedica) Orthopaedic Implants Division produces artificial joints, spinal rods and screws, artificial vertebral discs, bone cement and other biological products to grow bone.

In February 2009, Stryker released the Rejuvenate Modular Primary Hip System, an alternative to the Rejuvenate Modular Hip, which was approved by the U.S. Food & Drug Administration (FDA) in 2007. The Rejuvenate Modular Primary Hip System was the latest evolution in Stryker’s OmniFit and Secure-Fit Hip Systems, which were approved by the FDA in 2008. Because this hip implant was substantially similar to Wright Medical Technology’s ProFemur Total Hip Modular Neck System, which was already on the market, Stryker was able to submit the Rejuvenate through the FDA’s 510(k) approval process. In accordance with the expedited approval standards of the FDA’s 501(k) approval process, Stryker was permitted to sell its new hip implants without conducting pre-market clinical safety trials.

Even though Stryker was able to push the Rejuvenate implant through the expedited FDA approval process, the device that Stryker had been compared to and modeled after was plagued with complications. Wright’s ProFemur has been the target of many lawsuits due to the frequency of modular neck fractures caused by the corrosion of the metallic neck. The ProFemur’s failure rate was estimated to be greater than 11 percent when constructed with a titanium neck and cobalt chromium head. Wright constructed the product with titanium in an attempt to reduce the failure rate, but the problems persisted. In 2010, the ProFemur was approved for use with a ceramic head.

Both the ProFemur and the Stryker Rejuvenate hip implants have significant failure rates. Patients who received the implants experienced a number of symptoms, including pain, pseudo-tumors, and metal poisoning which stemmed from the hip replacement. In 2012, Stryker issued a voluntary recall of its Stryker Rejuvenate Primary Hip System.
