Periprosthetic fractures associated with osteolysis: a problem on the rise.

Periprosthetic fractures caused by osteolysis can occur in the pelvis, peritrochanteric area, or femoral diaphysis after hip arthroplasty. Most, but not all, hips are ultimately treated surgically to manage the osteolysis or to stabilize the fracture. Some stable, minimally displaced fractures of the pelvis and greater trochanter can be allowed to heal before revision is considered, which simplifies the operation. Unstable fractures, especially of the femoral diaphysis, are usually treated with early repeat surgery following the established principles of periprosthetic fracture management.
