Extended proximal femoral osteotomy: technical tip.

Extended proximal femoral osteotomy is a well-established technique in complex primary and revision hip surgery. It is commonly indicated for extraction of well-fixed femoral components either cemented or uncemented. Some of the problems encountered during this procedure are gaining an accurate reduction in the osteotomized fragment and a stable reduction and fixation. Here, we present a modification to the standard surgical technique which aids in anatomical reduction and enhances the stability of the reduced fragment. We make the distal transverse cut oblique rather than vertical. This modification allows for a more stable and anatomical reduction in the osteotomy. Our experience with this modified technique demonstrated 100 % union of the osteotomy.
