Spiral glenohumeral ligament

Last revised by Arlene Campos on 6 May 2024

The spiral glenohumeral ligament, also termed fasciculus obliquusligamentum glenohumerale spirale and spiral GHL, is a focal thickening of the glenohumeral joint capsule, akin to the other glenohumeral ligaments, yet it is not widely recognized 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.
