Periprosthetic Osteolysis — Imaging & Management
Periprosthetic osteolysis = bone loss from wear particle-induced inflammation. Detected on radiographs as radiolucencies, cystic defects; CT useful for mapping, MRI (MARS) for soft tissue. Must exclude infection before labeling aseptic osteolysis. Management: debridement of granuloma, bone grafting, bearing exchange, revision arthroplasty if components loose. Prevention: use of HXLPE, ceramics, optimal component position.
