[Apposition acetabular roof surgery with screw osteosynthesis and use of wedge osteotomy in intertrochanteric femur osteotomy].

After introductory presentation of the different methods of roofplasty of the hipsocket (including the osteotomies of the pelvis) relative to indication, advantages and disadvantages we describe a new technique of roofplasty for older children, adolescents and grownups, in which the wedge of the intertrochanteric femur osteotomy--up to now a by-product is used for a roofplasty similar to the combined operation with children. We give a presentation of the vertical and transverse apposition technique and especially of the advantage of the compression screw osteosynthesis. In particular we make a comparative evaluation to the concurrent pelvic osteotomy after Chiari. Above all we give a report of the experiences with 62 patients with 67 operations within a period of 7 years (1976-1982): We report the subjective and objective results. In general we achieved very satisfying results with a very low rate of complications.
