The medical equipment manufacturer Stryker Orthopedics has recalled its two hip implants voluntarily. The models that were recalled were Stryker Rejuvenate and Stryker ABG II as these had the same type of modular neck hip stem. There are other manufacturers such as Depuy and Zimmer that have also been recalled. The Michigan based Stryker has made over $8 billion, of which 13% was contributed by the hip implants before the Stryker Hip Recall was issued.
