Salvage total hip arthroplasty (THA) for failed internal fixations of proximal hip fractures

The failure of internal fixation methods may be due to various reasons like non-union, loss of fixation, femoral head osteonecrosis, post-traumatic arthritis, malunion, infection or symptomatic hardware. Simultaneous evolution of advanced methods of internal fixation of femoral neck and intertrochanteric fractures have reduced failure rates (2-3%) but in elderly and osteoporotic patients it still carries high risk of failure. Conversion arthroplasty in such failed fixations also known as salvage THA appears to be the promising treatment as it allows immediate ambulation and prevention of age related complications.
