Results of the Kalamchi modification of salter osteotomy in the treatment of developmental dysplasia of the hip.
The results of the Kalamchi osteotomy for acetabular dysplasia or subluxation secondary to developmental dysplasia of the hip are reported. In 16 hips, the modified innominate osteotomy was the sole procedure, whereas 10 hips had a concomitant shelf procedure and four hips had a concomitant femoral varus osteotomy. Using a modification of Severin's classification for radiographic evaluation, 97% of hips were classified as excellent (class I and II). Using McKay's criteria for clinical results, 93% of hips were classified as excellent or good. The advantages of this procedure are avoidance of limb lengthening, better stability of the osteotomy, no need for graft, and theoretically a decrease in pressure across the femoral head.
