Abstract
Background: There is a notch called the suprascapular notch on the superior border of the scapula at its lateralmost end which is converted into a foramen by the Superior Transverse Scapular Ligament (STSL). This foramen allows the passage of the suprascapular nerve which innervates supraspinatus and infraspinatus muscle. Ossification of the superior transverse scapular ligament led to entrapment neuropathy of the suprascapular nerve leading to disuse atrophy of these two rotator cuff muscles-supraspinatus and infraspinatus muscles- making it more prone to shoulder dislocation.
