Humeral avulsion of the posterior band of glenohumeral ligament
Updates to Case Attributes
The inferior glenohumeral ligament (IGHL) complex is comprised of three components. It consists of an anterior band, a posterior band, and an interposed axillary pouch. The anterior band usually is thicker than the posterior band. HAGL lesion is an important cause of anterior instability at the glenohumeral joint. An MRI arthrogram or joint effusion distends the joint and allows for better visualisation of IGHL defects. Specifically, the "U-shaped" axillary pouch stretched out of fluid becomes a "J-shaped" structure with extravasation of the contrast medium through the torn humeral attachment. HAGL lesions can be classified using the West Point Classification system,classification of humeral avulsion of the glenohumeral ligament (HAGL) which includes six types: anterior HAGL, anterior bony HAGL, floating anterior IGHL, posterior HAGL, posterior bony HAGL, and floating posterior IGHL.
