Modified technique for varus derotation osteotomy of the proximal femur in children

Abstract

Background: The results of a study in which the Richards' intermediate hip screw and the AO (Association for the Study of Internal Fixation (ASIF)) 90° fixed-angle blade plate were compared for use in proximal femoral osteotomy in children have previously been reported. In that study loss of position at the osteotomy site was reported as a specific complication associated with the use of the Richards' intermediate hip screw. Methods: The authors devised a simple modification of surgical technique using the Richards' intermediate hip screw to enhance the stability of the fixation. In the present article the results of a prospective study of that modified technique are reported and compared wi..
