Spiral glenohumeral ligament

Last revised by Deleted User on 06 Sep 2015

The spiral glenohumeral ligament, also termed fasciculus obliquusligamentum glenohumerale spirale and spiral GHL, is a focal thickening of the glenohumeral joint capsule, like the other glenohumeral ligaments, which has been described only relatively recently and it is not so well-known 1

Gross anatomy

The spiral glenohumeral ligament arises from the infraglenoid tubercle and the triceps tendon and has a joint insertion on the lesser tubercle of the humerus together with the subscapularis tendon 1.

The spiral glenohumeral ligament has been consistently demonstrated by anatomic dissection and on MRI 1.

Radiographic features

MRI

When visualized it is best appreciated as a hypointense structure on sagittal oblique and axial T1 and PD weighted sequences of MR arthrography 1.
