Stryker Orthopaedics is known for the development and manufacture of specialty surgical products and other medical supplies for health care around the world. The company has manufactured scores of medical devices and joint replacement products, most of which have been successful; however, some of the hip replacement devices have caused serious adverse events, injuring hundreds of patients.
The Stryker Rejuvenate Modular-Neck Stem and the ABG Modular-Neck Stem hip replacement devices were approved by the Food and Drug Administration (FDA) in 2008 and 2009. These devices are not typical "metal-on-metal" (MoM) as the necks are built of Cobalt and Chromium and the neck stems are layered with Titanium. Though the intention was to make it corrosion resistant, the two metals rubbed on each other at the connection and released toxic metal ions and debris. Stryker permanently recalled the Rejuvenate Modular and ABG II Modular-Neck Hip Stems in 2012 and stopped all global sales and production of these components. Another hip stem model, the Accolade TMZF, also caused problems and was recalled in 2009, 2011, and 2013.
Most patients with Stryker Rejuvenate and ABG II implants have undergone additional surgery or revision surgeries to remove and replace the implant to repair or reconstruct injured joints, bones, and tissues in addition to the replacement surgery.
