Anatomical terminology

It is a thin and flat fascicle, narrower at the middle than at the extremities, attached by one end to the base of the coracoid process and by the other to the medial end of the scapular notch.

The suprascapular nerve runs through the foramen; the transverse scapular vessels cross over the ligament.

The ligament can become ossified and impinge the underlying suprascapular nerve. This may cause paralysis of both supraspinatus and infraspinatus muscles.
