Purpose:
External snapping hip is caused by the iliotibial band snapping from the greater trochanter during hip movement. The aim of this study was to compare a technique of ultrasound-guided iliotibial band release versus a similar endoscopic technique.
Methods:
An anatomical study was performed on 10 cadavers i.e. 20 hips. The same operator performed ultrasound-guided and endoscopic iliotibial band release on either side of each specimen. An independent operator performed an open control to verify the outcome measures. The primary outcome was iliotibial cutting percentage, defined as the ratio of the transversal cut distance and the width of the iliotibial at the most prominent portion of the great trochanter. Secondary outcomes included nerve injuries. The surgical time was assessed and disposable medical supplies costs were estimated.
Results:
The average cutting percentage was 95% ± 8 by ultrasound, compared with 91% ± 11 by endoscopy (n.s.). No iatrogenic lesions were found, particularly nerve damage. The average duration of the ultrasound procedure was 12.3 minutes ± 6 compared to 21 minutes ± 10.7 for endoscopy (p=0.04), with a 3-fold decrease between the first and last procedure, regardless of the technique. The ultrasound procedure was 3 times less expensive in terms of disposable medical supplies (120.5€ versus 353.5€).
Conclusion:
This technique of ultrasound-guided iliotibial band release appears to be as effective and safe as a similar endoscopic technique. The surgical time is reasonable for a surgeon trained in ultrasound, with lower disposable supplies costs. A comparative clinical study is further needed to assess the actual benefits of each technique.
