Lateral Angle Of The Scapula, Posterior View

Description

Lateral angle of the scapula anchors the glenoid cavity at the superolateral corner of the shoulder blade, and this posterior perspective keeps the scapular spine as a dominant landmark running transversely toward the acromion. The glenoid fossa sits lateral to the scapular neck, with the infraglenoid tubercle positioned inferiorly as a bony prominence for the long head of triceps brachii, while the supraglenoid region lies superior to the articular surface. Medial to the lateral angle, the infraspinous fossa expands below the spine and the supraspinous fossa occupies the smaller depression above it. Orientation is unambiguous. The lateral border descends inferiorly from the glenoid toward the inferior angle, defining the posterior contour against the thoracic cage. Clinical relevance concentrates around the glenoid rim and scapular neck, where fractures, labral detachment, and osseous bone loss complicate recurrent anterior shoulder instability after dislocation. Orthopaedic readers will recognize why a posteriorly biased view helps, it clarifies the relationship between the spine, the neck, and the lateral angle without anterior structures obscuring the articular margin, which matters when planning screw trajectories for scapular neck fixation or when describing the bony landmarks used in posterior approaches to the shoulder. The infraglenoid tubercle is an easy teaching target here, and its position relative to the glenoid helps explain triceps-related pain patterns and traction injuries around the quadrilateral space. Use this illustration in gross anatomy labs and upper limb courses when students must identify scapular landmarks from the back, and in exam questions that distinguish the glenoid, acromion, and scapular spine in a single frame. It also fits orthopaedic and sports medicine publications discussing glenoid fractures, Bankart-type lesions with associated bony defects, and surgical planning for glenoid augmentation or shoulder arthroplasty templating.
