The Acromial Angle Of The Scapula From A Lateral View

Description

Angling in from a lateral shoulder perspective, the animation centers on the acromial angle, the posterolateral corner where the scapular spine expands into the acromion. As the scapula rotates in space, the acromion is seen projecting anteriorly over the glenoid cavity while the spine tracks posteriorly toward the medial border. The sequence keeps the acromial angle as the fixed landmark while the surrounding contours, including the supraspinous and infraspinous fossae, roll in and out of profile. Clinically, the acromial angle gives you a reliable bony reference when orienting the scapula during physical exam, open dissection, or when correlating radiographs and CT reconstructions of the shoulder girdle. Its relationship to the acromion matters in subacromial impingement and rotator cuff disease, where acromial morphology and the undersurface of the acromion can contribute to abrasion of the supraspinatus tendon. Animation earns its keep here by clarifying how a “lateral view” changes with scapulothoracic motion, so viewers stop confusing acromial angle, acromioclavicular region, and the lateral edge of the spine when the bone is reoriented. Use this clip to support osteology teaching in gross anatomy labs, to illustrate figure captions for orthopedic and sports medicine texts, or to orient readers before discussing lateral scapular (Y) views in trauma imaging and acromial fracture patterns.
