Techniques des butées de hanche

Abstract

Among current indications for conservative surgery of hip arthrosis secondary to acetabular dysplasia, shelf procedure is an intervention of choice because of its relative simplicity and the relatively short period of post-operative rehabilitation. Since the first procedure performed by M. Lance, techniques have changed. These changes concern essentially incision and soft tissue exposure. Such as in any hip surgery, minimal invasive surgery appears the preferential choice as it limits the occurrence of complications and shortens the recovery period. Shelf procedure is indicated in case of a patient under 40 years, with a hip arthrosis secondary to acetabular dysplasia, without any abnormality of the upper femoral extremity and with a narrowing of the joint space less than 50%. In case of any morphologic deformation of the femoral upper part, correction must be undertaken during the same operative procedure. Good results can be expected for up to 10 years or more provided both the indication and the surgical technique have been correctly determined. Hip shelf procedure is usely propose about 40 years of age.
