Neck Of The Scapula, Posterior View

Description

Scapular neck (collum scapulae) occupies the narrowed bony segment immediately medial to the glenoid cavity and head of the scapula in this posterior view, where the lateral border thickens as it approaches the articular margin. Posteriorly, the scapular spine runs transversely toward the acromion, separating the supraspinous fossa superiorly from the broader infraspinous fossa inferiorly, while the glenoid rim sits lateral to these fossae as the socket for the humeral head. An indentation adjacent to the glenoid, at the junction of spine and lateral border, outlines the region of the spinoglenoid notch. Focus stays on the lateral angle. Scapular neck anatomy matters in shoulder girdle trauma because fractures through the collum scapulae can alter glenoid version and medialize the glenoid fragment, a pattern often seen after high-energy injury and frequently discussed alongside “floating shoulder” when accompanied by clavicular disruption. The posterior perspective places the glenoid neck in relation to the scapular spine and infraspinous fossa, which helps when correlating physical bony landmarks with CT reconstructions or with a posterior surgical approach for glenoid-neck fixation. The spinoglenoid region also carries clinical weight, since ganglion cysts or traction can compress the suprascapular nerve near the spinoglenoid notch and selectively weaken the infraspinatus. Orthopedic educators can pair this illustration with lessons on scapular fracture classification, glenoid neck alignment, and posterior approaches to the lateral scapula in trauma courses and shoulder fellowships. Medical publishers and radiology teaching files can use it to annotate the neck of the scapula relative to the glenoid cavity, scapular spine, and infraspinous fossa for cross-sectional imaging correlation.
