Typically, patients with failed internal fixation of a hip fracture have marked pain and disability. These patients may present treatment challenges. Salvage is tailored to the anatomic site of the nonunion, the quality of the remaining bone and articular surface, and patient factors such as age and activity level. ⋯ For conversion to arthroplasty, the major challenges are assessing the need for acetabular resurfacing, selecting the femoral implant, and managing the greater trochanter. Technical challenges include broken hardware, deformity, and femoral bone defects. Attention to technical details can minimize potential complications.
