Sumario:Sciatic nerve impingement via a tumor of or trauma to the proximal subgluteal region creates a considerable surgical challenge that is debated in the literature. The neurosurgery literature favors the infragluteal approach, while in orthopaedics, the transgluteal approach is preferred. The goal of our study was to present an operative technique for the infragluteal approach to the subgluteal region with a step-by-step procedural guide to increase awareness among orthopaedic surgeons of alternative surgical approaches to the sciatic notch. We retrospectively reviewed the case of a 62-year-old female found to have a subgluteal myxoma who underwent the infragluteal approach for tumor excision. We then highlighted the anatomic considerations via cadaveric dissection photographs, artistic renditions, and intra-operative images. Our patient underwent tumor resection and sciatic nerve exploration via the infragluteal approach with a successful outcome. In comparison to other approaches in the literature, the infragluteal approach provides a safer dissection with more options for an extension of the exposure and potentially fewer functional deficits. We conclude that orthopaedic surgeons should strongly consider utilizing this approach to the sciatic notch rather than a transgluteal approach.
