[Implementation of McMurray displacement in adduction osteotomy with AO-instruments (author's transl)]

Pre- and postoperative radiographs of 60 patients with intertrochanteric varisation osteotomy by using AO instruments were reviewed and measured. Obviously a combination of the varisation osteotomy with McMurray's medial displacement is either very difficult or impossible especially in cases with long femoral neck and large displaced intertrochanteric wedge. Both construction of a fixation plate for more medial displacement of the femoral shaft as well as not doing major varisation when the femoral neck is very long are discussed as alternative methods of operation.
