Abstract
We describe a previously unreported technique of Z-lengthening for the treatment of refractory trochanteric bursitis and review the long-term outcomes for this procedure.
Fifteen patients (17 hips) were diagnosed with trochanteric bursitis based on clinical criteria. These patients were found to be unresponsive to conservative treatment including multiple corticosteroids injections. “Snapping Hips” were excluded. All went on to have bursectomy and Z- lengthening of the iliotibial band.
Harris Hip Scores were evaluated for before and after their operation as well as a standardised baseline questionnaire and examination.
At mean follow up of 47 months following Z-lengthening, eight patients reported excellent results with complete resolution of symptoms, eight had good results with symptoms improved and one had a poor result. One patient required secondary repair of a tear in the tendon of gluteus minimus with a subsequent excellent result. The mean Harris Hip Score improved from 46 to 82 (p< 0.05).
Bursectomy and Z-lengthening has been shown to be an effective and long-term operative solution for the treatment of refractory trochanteric bursitis when conservative measures have failed. Although the majority of patients had a successful outcome, not all respond well to this procedure and careful patient selection is recommended as well as a pre-operative MRI to rule out concomitant pathology such as a tear in the Gluteus medius or Gluteus minimus.
