A Humeral Avulsion of the Glenohumeral Ligament, or HAGL lesion, is an uncommon yet disabling shoulder injury, which leads to complaints of pain and overall inability to properly use the shoulder from patients. While a posterior HAGL lesion is repaired arthroscopically, an anterior HAGL lesion is treated through an open approach. Often, these can be missed due to chronicity of the injury, and potential imaging, and can lead to pain, instability and dysfunction of the shoulder.  The following presents my preferred technique to surgically treat an anterior HAGL lesion through an open approach to help restore shoulder instability and function of the shoulder joint.
