Abstract

Objectives: To describe the surgical technique for an endoscopic sciatic nerve release in deep gluteal syndrome and to evaluate its results. Study design and Methods. Retrospective observational study of a consecutive case series that underwent endoscopic surgery by the Arthroscopy Unit from our hospital. All of them were diagnosed clinically and radiologically (using magnetic resonance imaging) of sciatic nerve entrapment. Results. Eight patients underwent surgery with a mean age of 44 years old and a majority of women. The mean duration of surgery was 55 minutes with a mean hospital stay of one day. Anatomical muscular alterations were found in six cases and fibrovascular bands in two. Pain, assessed by Visual Analogue Scale (VAS), decreased from 8'00 to 2'25. The patients were on average quite satisfied. One complication was described and just one case required salvage surgery. Conclusions. Sciatic nerve release is an effective technique in patients with subgluteal space syndrome due to sciatic entrapment, since it improves the patient's symptoms. The use of endoscopy provides added value, as it allows visualization of the nerve using minimally invasive techniques.
