Acromial Angle Of The Scapula, Lateral View

Description

Acromial angle anatomy anchors this lateral shoulder-girdle illustration, centering on the junction where the scapular spine meets the acromion. From a true lateral perspective, the acromion projects anteriorly over the glenoid cavity, while the spine runs posteriorly and medially into the scapular body, defining the transition between the supraspinous and infraspinous regions. The glenoid fossa sits inferior and slightly anterior to the acromial angle, and the lateral border and scapular neck form the osseous strut between the articular surface and the blade. A sharp bony corner. That corner matters in daily clinical work because it defines palpable surface anatomy and sets the roof over the subacromial space, where the supraspinatus tendon and subacromial bursa are vulnerable in external impingement syndromes and rotator cuff tendinopathy. The acromial angle also frames the posterior aspect of the acromioclavicular region, a common site of sprain and post-traumatic osteolysis, and it lies adjacent to attachment footprints for deltoid (acromial part) and trapezius that surgeons respect during superior shoulder approaches. Strong raking light across the acromion and spine makes their ridge lines and margins legible, helping the viewer judge orientation without relying on surrounding soft tissues. Use this illustration in gross anatomy and kinesiology modules when teaching scapular landmarks, in orthopedic and sports-medicine texts discussing subacromial impingement and AC joint injury, or in patient-facing educational materials that explain why pain localizes at the top and lateral aspect of the shoulder. It also fits preoperative planning references that need consistent bony geometry for portal placement and incision planning around the acromion and scapular spine.
