Total hip arthroplasty (THA) predictably provides pain relief and improved function in patients with degenerative hip arthritis. Despite the overwhelming success of THA, several situations necessitate the revision of the femoral component. The extended trochanteric osteotomy (ETO) is an essential surgical tool for the revision arthroplasty surgeon. To obtain a successful surgical result during femoral revision, the femoral stem must be removed with minimal bone loss, the remaining host bone must be prepared without inadvertent perforation, and a femoral implant must be inserted concentrically with adequate axial and rotational stability.
