Abstract
Total 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.
