Abstract
Hip osteoarthritis in its final stage may require arthroplasty. Sometimes an extreme Z-deformity of the proximal femur is present, if a previous valgus trochanteric osteotomy has been performed. To correct a Z-deformity of the proximal femur during total hip arthroplasty, a subtrochanteric corrective osteotomy was performed in a 52 year-old woman. Intramedullary fixation of the osteotomy was secured using a standard long-stem isoelastic femoral component alone.
