Extract

Osteolytic lesions may develop after total hip arthroplasty from a biologic reaction to particulate debris. Loss of bone results from osteoclastic resorption and can be seen on radiographs as cystic lesions or radiolucent regions in proximity to the femoral and acetabular components. Osteolysis may be associated with pain, particularly if bone loss results in decreased mechanical support for the prosthetic components and implant loosening. However, osteolysis may also be asymptomatic and only detected with radiographic or other imaging modalities.
