The Posterior Surface Of The Scapula In Posterior View

Description

Across the dorsal surface of the scapula, the animation traces the scapular spine as it courses obliquely from the medial border toward the lateral angle, expanding into the acromion and splitting the bone into the supraspinous fossa superiorly and the infraspinous fossa inferiorly. The medial (vertebral) border runs parallel to the thoracic wall, while the lateral (axillary) border descends toward the inferior angle. Lateral rotation brings the glenoid region into context at the superolateral corner, with the spine and acromion projecting posteriorly over the shoulder. Bony relief changes with the rotating posterior view. Teaching scapular anatomy often fails when learners cannot reconcile surface landmarks with functional muscle compartments, and that is exactly what this sequence clarifies. By showing the spine as a palpable ridge and the fossae as distinct basins, the animation supports accurate placement of supraspinatus and infraspinatus origins and the relationship of posterior scapular contours to rotator cuff pathology. It also frames the acromion as a posterior extension that becomes relevant in subacromial impingement and during posterior portal planning for shoulder arthroscopy, where orientation to the spine and acromion guides safe trajectories. Use it in gross anatomy lab prep, musculoskeletal radiology introductions that correlate posterior scapular landmarks with AP and scapular Y projections, or orthopedic education materials explaining posterior shoulder approaches and scapulothoracic mechanics. It also fits publisher graphics for rotator cuff chapters where readers need fast orientation to the supraspinous versus infraspinous regions.
