The reciprocal ledge closing wedge osteotomy for post traumatic coxa vara.

To report a proximal femoral osteotomy with retention of bone ledges in a reciprocal position to increase bone contact and stability. The method was applied to 5 patients over a 3-year period. All patients had coxa vara. The average length gained was 1.5 cm, and the average neck shaft angle improvement was 30°. The Harris hip score improved from an average of 63 to 82. The reciprocal ledge osteotomy is technically less demanding and also allows conversion of normal shear forces around the upper femur to stabilizing forces. This method allows easier use of the DHS implant as potential rotation about the axis of the screw is negated by the ledges and the dynamic forces.
