Abstract
AbstractTotal hip arthroplasty (THA) has been referred to as the operation of the century given its success and predictable improvement in quality of life. With the increase in number of THAs performed every year, there is a concomitant rise in the incidence of revision and re-revision surgeries. Failure of THA and revision hip arthroplasty may occur due to a variety of reasons, often in older patients with multiple comorbidities. Revision procedures in this setting are associated with worse outcomes as they are often complicated by limited bone stock and poor soft tissue and bone quality, making reconstruction more challenging. The purpose of this review is to discuss modern techniques for limb salvage following failed THA in the setting of significant bone loss. These include proximal femur replacement, total femur replacement, hip resection arthroplasty, and hip disarticulation.
