Abstract

Periprosthetic acetabular fracture (PAF) is an uncommon complication following hip arthroplasty. However, as the number of people needing hip prostheses continues to rise, the absolute number of PAF is expected to increase as well. These fractures may occur either intraoperatively or postoperatively. Postoperative fractures can be caused by traumatic events or by pathologic conditions related to periacetabular osteolysis. The management of PAF usually depends on the degree of displacement and the stability of the acetabular component. While most of non-displaced fractures can be managed nonoperatively by protected weight bearing, displaced fractures with unstable implants require surgical intervention, which is often technically challenging. This review summarized the latest findings on the epidemiology, the diagnosis, the classification, and the treatment of PAF.
