[Experimental substantiation of a transosseous approach in arthroplasty of the hip joint].

The author analyses the results of 40 experimental operations on cadavers to work through and to improve the approach for the hip joint arthroplasty performed by means of intertrochanteric osteotomy of the femur. The main parameters of the approach at various stages of the procedure have been evaluated according to O. Y. Sozon--Yaroshevich, the traumatizing factors of the operation have been determined and the peculiarities of mobilization of the proximal part of the femur and the possibility of displacement of the femoral head in various directions have been studied. Variations of the approach have been proposed taking into consideration the degree of limitation of the movements and the character of pathologic changes in the joint for performing hip joint arthroplasty in clinical practice. An approach to the supraacetabular area from the part of the joint cavity has been worked out which preserves the gluteal muscles, at the same time allowing to perform the arthroplasty and to reconstruct the supraacetabular area.
