Scapular Body, Posterior View

Description

Scapular body anatomy dominates this posterior view, with the scapular spine running transversely across the dorsal surface and separating the smaller supraspinous fossa superiorly from the broader infraspinous fossa inferiorly. Laterally, the spine expands toward the acromion, while the medial (vertebral) border and inferior angle frame the broad, triangular plate. The lateral (axillary) border thickens as it approaches the glenoid region, and the smooth subcutaneous plane of the infraspinous fossa contrasts with the ridge-like contour of the spine. Bony landmarks read at a glance. Understanding the posterior scapula matters whenever scapulothoracic mechanics or rotator cuff function is on the table, because the supraspinatus and infraspinatus arise from their respective fossae and converge toward the greater tubercle of the humerus, and the scapular spine serves as a palpable reference for localizing pain, guiding examination, and orienting surgical approaches. Acromial morphology and the lateral continuation of the spine also anchor discussion of subacromial impingement and acromioplasty planning, even when the primary focus is the scapular body. The fixed posterior perspective helps distinguish true bony relief from muscle bulk, making the borders and angles easier to teach than in photographs where soft tissue obscures contour. Orthopedic and sports medicine lectures on scapular dyskinesis, rotator cuff tears, and acromioclavicular joint injury can pair this illustration with shoulder girdle kinematics and surface anatomy palpation labs. Anatomy and physical therapy courses can use it to reinforce Terminologia Anatomica for the spina scapulae, fossa supraspinata, fossa infraspinata, angulus inferior, and margo medialis, and publishers can drop it into chapters on the pectoral girdle without extra annotation.
