Many of problems seen in Stryker hip recall patients are the result of microscopic metal ions that are shed from the hip stems when they fret or corrode. These minute particles can accumulate in the tissue surrounding the hip, as well as the blood stream, leading to any number of serious Stryker hip replacement problems, including:
- Metallosis: A rare condition that is caused by the buildup of metallic debris in the soft tissue of the body
- Osteolysis: The loss of bone around the hip. Osteolysis is the most common hip replacement complication, and has been named as the cause of nearly 75 percent of all hip implant failures
- Necrosis or tissue death
- Loosening and dislocation of the implant
- Fracture of the implant
- Device failure requiring revision surgery
Stryker has advised all Rejuvenate and ABG II hip recipients to undergo blood tests for metal ion levels and imaging screening, even if they are not experiencing any apparent Stryker hip recall problems. According to the company, some patients implanted with these components have tested positive for elevated metal ions and adverse local tissue reactions, even in the absence of symptoms.
