Abstract
Multidirectional shoulder instability represents an ongoing challenge for orthopaedic surgeons, and multiple techniques have been described to treat this condition. We present a modified anterior shoulder ligamentoplasty, in which we perform an inferior glenohumeral ligament (IHGL) anteroinferior and posteroinferior plication and, subsequently, an anterior reinforcement ligamentoplasty with an allograft through the subscapularis tendon, with humeral and glenoid fixation. This arthroscopic technique allows shoulder stability in the throwing position, as the humeral head is not uncovered in abduction, and external rotation by ascending the subscapularis tendon.
