Endoscopic Treatment of Greater Trochanteric Pain Syndrome - A Case Series of 11 Patients.J Orthop Case Rep. 2019 Jan-Feb; 9(1):6-10.JO
Greater trochanteric pain syndrome (GTPS) includes patients with symptoms of peritrochanteric pain, gluteus medius/minimus tendinopathy, and external snapping hip. Non-operative treatment includes iliotibial band (ITB) stretching, gluteal exercises and cortisone injections. When surgery is indicated due to the failure of non-operative strategies, open Z-plasty at the level of the greater trochanter has been the traditional procedure. Endoscopic release of the ITB and bursectomy at the level of the greater trochanter has over the last decades evolved and is established as an alternative method of surgery.
We here present a case series with 11 consecutive patients who have undergone endoscopic release of the ITB and bursectomy at the level of the greater trochanter due to GTPS. The patients were all Caucasians, 43-years of age, and six were female. The patients retrospectively scored their pre-operative function and pain during follow-up at 28 months (range 15-42). Post-operative pain and function were scored at follow-up. In this paper, we discuss investigation, differential diagnoses, surgical options, and outcomes in the treatment of GTPS. All patients reported significant reduction of pain, and 10 of 11 patients reported an improvement in function. We observed no complications.
Endoscopic release of the ITB and bursectomy at the level of the greater trochanter appears to be an effective and safe procedure when conservative treatment options for GTPS have failed.
