Early results of endoscopic trochanter bursectomy.

Between 1995 and 2000, we performed 45 endoscopic bursectomies in 42 patients (average age 51, range 17-61 years). All patients had at least 6 months of failed conservative treatment, and all responded positively to a sonographic-guided injection with Mepivacaine 0.5%. The bursa was removed using a synovial resector. An additional tractopexie was performed in four cases. We followed 37 patients for 12-48 months. Pre-operatively, the mean modified Japanese Orthopaedic Association (JOA) disability hip score was 40.5 points. It improved to 72.6 points after a mean of 25 months. Severe complications did not occur. The minimally invasive technique requires only stab incisions, and immobilisation and hospitalisation are minimal.
