Management of Intraoperative Acetabular Fractures During Total Hip Arthroplasty

Intraoperative fractures of the acetabulum are a rare but serious complication during total hip arthroplasty. Acute fractures generally require attention with plating, whereas chronic acetabular fractures may be approached with distraction, a Burch-Schneider cage, or a custom implant. It is imperative for arthroplasty surgeons to possess a thorough understanding of how to identify and manage these injuries. Collaborating with an orthopedic traumatologist for assistance with plating the anterior or posterior column, if necessary, can be invaluable. Management options encompass conservative management, revision style acetabular component, screw/plating of anterior/posterior column, and the use of a larger cup with multiple screw augmentation options.
