Spiral glenohumeral ligament

The spiral glenohumeral ligament (fasciculus obliquus, ligamentum glenohumerale spirale and spiral GHL) has been described relatively recently and is not well known but seems constant in MRI and dissection.

As other glenohumeral ligaments, it is a band of the glenohumeral joint capsule that runs from the infraglenoid tubercle and the triceps tendon to insert on the lesser tubercle of the humerus together with the subscapularis tendon.

In MRI arthrogram, it appears as as a low signal intensity stripe within the superficial layer of the anterior joint capsule.
