Arthroscopic Resection of Symptomatic Bennett Lesions

Bennett lesions, also known as “thrower's exostosis” of the shoulder, involve ossification of the posteroinferior glenoid and are not uncommon in overhead throwing athletes. The literature surrounding the optimal operative management of the symptomatic Bennett lesion is limited. The purpose of this article is to describe the arthroscopic surgical technique for the visualization and excision of the symptomatic extra-articular pathologic ossification involving the posteroinferior glenoid. Because many surgeons may not be familiar with this problem or procedure, we present a straightforward method that allows for identification and excision of the exostosis through an arthroscopic posterior arthrotomy.
