Coxa saltans externa treated with Z-plasty of the iliotibial tract in a military population

Coxa saltans, or snapping hip, can be attributable to a number of causes. Coxa saltans externa typically occurs when the thickened portion of the iliotibial band snaps over the greater trochanter as the hip is flexed. This condition generally resolves with a course of nonoperative treatment. We have treated three patients with Z-plasty of the iliotibial band, which has the highest published success rate in the English language literature. Only one of three patients was able to return to full activities postoperatively. In our small series, this method of surgical treatment in an active duty military population yielded less than optimal results.
