Z-PLASTY LENGTHENING OF THE ILIOTIBIAL BAND FOR THE SNAPPING HIP

Abstract

Between 1993 and 1998, 16 consecutive hips in 12 patients (3M, 9F) with a mean age of 22 yrs (14–38 yrs), and mean time of symptom onset from surgery of 35 mths (9–60 mths) underwent Z-plasty of the iliotibial band for snapping hip. At mean follow-up of 36 mths (15–60 mths), all 16 hips (12 patients) were free of snapping whilst 14 hips (11 patients) experienced complete relief of symptoms. All patients considered the procedure successful and worthwhile, and there were no complications. We conclude that, in select patients who experience painful snapping of the hip because of a tense iliotibial band that has failed non-operative measures, iliotibial band lengthening by Z-plasty has been successful at improving or completely abolishing hip pain and snapping.
