The radiographs provided indicate the biodegradable cement restrictor has degraded; literature suggests further deterioration of the hip prosthesis may occur, placing the joint at risk of fracture.Although it is associated with osteolysis, it is not clear if the phenomenon is caused by the device or if other physiologic processes/interactions are contributory.Field safety corrective action (fsca-o-hhe-701) was undertaken to provide safety alert to physicians regarding the possible risk.At or around that time (2014), market withdrawal and destruction of unused product occurred.The prosthesis remains implanted; no revision has occurred.This is consistent with the majority of similar reports.
