Stryker Orthopaedics issued a voluntary recall of its Rejuvenate Modular and ABG II modular-neck hip stems. According to Stryker, there are concerns that the stems might cause corrosion, leading to pain and swelling indicative of adverse local tissue reaction.
According to a clinical information study funded by Stryker, the use of modular necks was intended to allow greater precision when operating on artificial hip recipients. But the risk of metal corrosion has linked to such devices has called their safety into question.
Stryker’s recall is representative of the safety concerns involved with all metal-on-metal hip replacement systems. The implants use all-metal components, which can release metal ions when they rub together. The devices have been linked to high failure rates, pseudotumors, metallosis, bone loss, soft tissue reactions and other complications.
