Scapular Notch Of The Scapula, Anatomy

Description

Suprascapular notch anatomy is centered on a semicircular concavity along the superior border of the scapula, just medial to the base of the coracoid process and lateral to the scapular spine’s root. From a superior aspect of the shoulder blade, the notch sits at the transition between the supraspinous fossa posteriorly and the costal (subscapular) surface anteriorly, with the superior border forming a thin osseous bridge between these regions. The adjacent superior angle lies medial and posterior, while the glenoid cavity remains lateral and slightly inferior in the same frame. Bone detail is the focus. Clinically, the notch is the gateway to the supraspinous fossa because the suprascapular nerve typically passes beneath the superior transverse scapular ligament, while the suprascapular artery more often courses superior to the ligament, a relationship that explains common exam phrases like “Army over Navy.” Variation matters: a narrow V-shaped notch, ligament ossification, or a complete bony foramen can predispose to suprascapular nerve entrapment, producing deep posterolateral shoulder pain and weakness of supraspinatus and infraspinatus. A single fixed perspective that emphasizes the superior border and the coracoid base helps you localize where surgeons decompress the nerve and where radiologists scrutinize CT or MRI for notch morphology. Orthopedic and sports-medicine texts can pair this illustration with discussions of rotator cuff weakness patterns, paralabral ganglion cysts at the spinoglenoid notch, and differential diagnosis of shoulder blade pain. Gross anatomy courses and cadaver-lab guides often need a clean scapula reference for orienting superior, medial, and lateral landmarks on the thoracic skeleton, and this image supports those labeling tasks without distraction from surrounding soft tissues.
