Endoscopic Iliotibial Band Release is an Effective Treatment for External Snapping Hip Syndrome: A Case Series

Introduction External snapping hip syndrome (ESHS) is characterized by a snapping sensation and potential pain, particularly during hip flexion and extension. It affects the young and athletic population, and its principal cause is a tight iliotibial band (ITB) sliding over the greater trochanter (GT). Multiple surgical interventions have been proposed when conservative treatment fails. However, the open techniques are associated with slower mobilization, large scars, and relatively high complication rate compared to the endoscopic procedures. Material and methods This study retrospectively examines the clinical outcomes of endoscopic ITB release using a modified Ilizaliturri method in seven patients diagnosed with ESHS, following unsuccessful conservative management. The endoscopic technique involved a cross-shaped incision on the ITB, allowing for effective release. The modified Harris Hip Score (MHHS) and Hip Outcome Score (HOS) were utilized to measure improvement. Results Six patients experienced uneventful recoveries, with one minor complication that resolved spontaneously. In a mean follow-up of 25 months, there was no recurrence of symptoms. Statistical analysis revealed significant improvement of both MHHS and HOS. Conclusion The present study demonstrates that this endoscopic procedure is a safe and effective option for managing ESHS, presenting favorable outcomes with minimal complications. Further research with larger sample sizes is necessary to establish comprehensive comparisons between open and endoscopic techniques.
