title: Outcomes of post-operative periprosthetic acetabular fracture around total hip arthroplasty.
abstract: Post-operative periprosthetic acetabular fractures are rare, but serious complication following total hip arthroplasty (THA). As the number of THA performed each year increases so will the expected number of periprosthetic fractures, thus making the treatment of these fractures an important topic for discussion. The purpose of this review is to analyze the recent evidence on risk factors, fracture classification schemes and treatment strategies that have been used for periprosthetic acetabular fractures around THA. The modified Paprosky classification is the most widely used and is a useful guide for management strategies. This classification system provides the guidelines for developing multiple treatment algorithms for decision making. Treatment options for surgical management include open reduction and internal fixation with plating, use of reconstruction cages, trabecular metal augments and bone grafting as needed. Treatment decisions are still an area of controversy and current research.
