Arthroscopic Posterior HAGL Repair Using a Direct Transaxillary Portal

Abstract

Humeral avulsion of the glenohumeral ligament (HAGL lesion) is a challenging problem in surgery for shoulder instability. Open and arthroscopic approaches and techniques have been described to address this issue. Especially posterior HAGL lesions increase the surgical complexity, as open anterior approaches provide limited visibility and access for successful repair. This article describes an alternative technique using an arthroscopic transaxillary approach to deploy the suture anchor with a perpendicular angle to the humeral bone, thus, improving the ability to perfectly position the anchor at the anatomic insertion of the inferior humeral ligament.
