Preoperative planning is important to reduce operating time and obtain a good end result. A 95 degrees blade-plate is used, and if necessary, a small wedge is excised to ensure coaptation of the osteotomy segments. The results of the procedure in 17 patients show that eight patients have a satisfactory result at a mean of three years, while three patients continue to have problems. Five patients have been converted to total hip arthroplasties, and one has a girdlestone arthroplasty. The unsuccessful results occurred in patients who were on corticosteroids or had continued metabolic bone abnormalities.
Present experience confirms reports of other series.
The operation should be offered only to the small group of patients with idiopathic, posttraumatic, or alcohol-induced osteonecrosis of the femoral head.
