Surgery

As the number of primary total hip arthroplasty (THA) procedures performed continues to rise, the burden of revision THA procedures is also expected to increase. With patients undergoing THA at younger ages and living longer, revision patients are presenting with greater bone loss at the time of revision surgery. The proper evaluation and treatment of acetabular bone loss at the time of revision surgery is complex and is further complicated in the face of a chronic pelvic discontinuity. Identifying proper pre-operative patient assessment in conjunction with detailed pre-operative planning is essential for obtaining favorable clinical results. Appropriate radiographs are critical in assessing acetabular bone loss, and specific classification schemes can identify bone loss patterns and guide available treatment options. The presentation reviews the surgical decision making and clinical results of different surgical options for the treatment of acetabular bone loss, and introduces a novel technique for the treatment of a chronic pelvic discontinuity.
