Salvage total hip arthroplasty (THA) presents a viable solution for failed open reduction internal fixation. This study compares salvage THA in patients with prior femoral neck fractures vs patients with prior intertrochanteric fractures. One hundred fifty-four hips in 152 patients underwent conversion from open reduction internal fixation to THA. Eighty-three patients had previous femoral neck fractures, and 69 patients (71 hips) had prior intertrochanteric fractures. Salvage THA in patients with prior intertrochanteric fractures presented a more technically demanding procedure with longer operative times and larger amounts of blood loss. Although conversion THA presents a technically challenging procedure, it is safe and yields relatively few orthopedic complications.
