Oblique proximal femoral osteotomy for hip containment and correction of femoral torsion

ABSTRACT

We present twenty-seven cases [thirty two hips] where proximal femoral osteotomy was needed either to contain the femoral head concentrically within the acetabulum or to correct femoral torsion. The different indications included ten cases with Perthes' disease; eight cases with developmental dysplasia of the hip [DDH]; and nine patients [fourteen hips] with intoeing due to medial femoral torsion. In this procedure the degree of obliquity of the osteotomy was determined from special graphic curves designed for this purpose. The obliquity of the osteotomy was found to fulfill certain advantages including simultaneous correction of deformities in different planes, having wide surface of bone contact at osteotomy site, avoiding excessive shortening, achieving better stability, and better control on the bony fragments. This was reflected on the results achieved where we did not have any case of nonunion, implant failure, under- or over-correction
