The Original Mini-Open Technique for Repair of Humeral Avulsion of the Glenohumeral Ligament.

ABSTRACT: Anterior shoulder dislocations commonly occur in the young, athletic population. The mechanism of dislocation occurs when the shoulder is placed in an abducted, externally rotated position while a forceful anterior moment is applied to the humerus. This position, combined with the force applied, results in an anterior and inferiorly directed dislocation of the humeral head away from the glenoid. Due to the limited stretching capacity of the glenohumeral capsule and associated glenohumeral ligaments, the force of the traumatic dislocation overcomes the tensile strength of these ligaments, resulting in a tear. Although the injury more commonly results in an avulsion of the anteroinferior capsulolabral complex from the glenoid, called a Bankart lesion, other injuries have been described. The anterior inferior glenohumeral ligaments (aIGHLs), may be torn from their humeral attachment, which is referred to as a humeral avulsion of the glenohumeral ligament (HAGL). Although other structures may be injured, the topic of this surgical technique focuses on a mini-open approach for repair of the HAGL lesion.
