Humeral Avulsion of the Glenohumeral Ligament (HAGL) is an injury to the inferior glenohumeral ligament causing instability and/or pain and a missed cause of recurrent shoulder instability. Diagnosis requires suspicions of injury and can be noted as an inferior pouch irregularity on MRI.

2023年7月27日 · Humeral avulsion of the glenohumeral ligament most often results from anterior shoulder dislocation due to forced hyperabduction and external rotation of the arm 6. MRI is the modality of choice for the assessment of HAGL, especially as the finding may be difficult to diagnose on arthroscopy.

HAGL tears occur most often when the person has the arm in a position of abduction (away from the body) and external rotation (outward rotation). Think of a pitcher’s arm after the wind-up and just before releasing the ball or how you would hold your hand under your head when lying on the ground looking up at the stars.

Some HAGL tears can be repaired by arthroscopy, but often an open surgical repair is better to access it properly. HAGL tear. The image on the right shows the HAGL as seen at arthroscopic surgery: The patient is placed onto their side or in a beach chair position, with the operative arm in traction and slightly abducted from the side their body.

Humeral avulsion of the glenohumeral ligament (HAGL) is defined as an avulsion (tearing away) of the inferior glenohumeral ligament from the anatomic neck of the humerus. [1] In other words, it occurs when we have disruption of the ligaments that join the humerus to the glenoid.

The inferior glenohumeral ligament, the most important static anterior stabilizer of the shoulder, becomes disrupted in humeral avulsion of the glenohumeral ligament (HAGL) lesions. Unfortunately, HAGL lesions commonly go unrecognized. A missed HAGL during an index operation to treat anterior shoulder instability may lead to persistent instability.

2017年3月14日 · Humeral avulsion of the glenohumeral ligament (HAGL) is a lesion associated with anterior shoulder instability. Although uncommon, HAGL lesions are a significant contributor to shoulder pain and dysfunction and, if missed, can even be a cause of failed Bankart repair.

Treatment of a Combined Pectoralis Major Tear, Anterior Labral Tear, and Humeral Avulsion of the Glenohumeral Ligament (HAGL) in an Active Duty Soldier. Military Medicine. 2022;187 (3-4):e530-e534. doi:10.1093/milmed/usaa422 [DOI] [PubMed]

2025年4月4日 · Summary HAGL lesions are an important yet often under-recognized cause of shoulder instability. Surgery is indicated in most cases due to its positive results, though comparative data between arthroscopic and open approaches are limited. Future research should refine imaging accuracy, directly compare arthroscopic versus open approaches, and enhance rehabilitation to improve pre-injury RTS ...

Humeral avulsion of the glenohumeral ligament (HAGL) is a traumatic lesion of the inferior glenohumeral ligament (IGHL), which occurs at its humeral insertion or in mid-portion (in opposition to GAGL, which is found at the glenoid insertion of IGHL).
