Abstract

Scapular exostoses are rare, and ventral lesions are more common than dorsal lesions. Scapular exostoses can cause symptoms including pain and mechanical crepitus due to scapulothoracic bursitis, decreased active range of motion, "pseudowinging" of the scapula and snapping scapula. Surgery is indicated for symptomatic scapular exostosis. Although open surgical resection remains the standard approach, it is associated with significant tissue disruption and longer rehabilitation. The purpose of this technical note is to report the details of endoscopic resection of exostosis at the medial border of scapula. This technique is feasible for lesions at dorsal or ventral side of the scapula.
