A Front View Of The Supraglenoid Tubercle Of The Scapula

Description

Framed from an anterior (costal) shoulder-girdle perspective, the animation centers on the supraglenoid tubercle at the superior margin of the glenoid cavity of the scapula. The bony prominence sits superior to the glenoid fossa and medial to the base of the coracoid process, with the scapular neck tapering inferiorly toward the infraglenoid region. As the sequence subtly reorients the scapula, the spatial relationship between the glenoid rim, scapular body, and lateral border becomes easier to read. Small landmark. Big consequences. Functionally, the supraglenoid tubercle anchors the long head of the biceps brachii via the proximal biceps tendon and the superior labrum, so tiny changes in this area can translate into anterior shoulder pain or mechanical symptoms. Labral lesions (including SLAP tears) and biceps anchor pathology are often discussed in the same breath as the supraglenoid region, but static diagrams rarely convey how close the tendon’s origin lies to the articular margin and how little bone separates the attachment from the joint surface. By moving through a controlled anterior orientation, the animation clarifies why arthroscopic portals and instrument trajectories must respect the superior glenoid rim and adjacent coracoid base. Use this clip in gross anatomy and kinesiology modules on the pectoral girdle, in orthopaedic and sports-medicine teaching on biceps tendinopathy and SLAP repair, or as a figure supplement for papers and slides that reference the biceps anchor on the scapula. It also suits patient-facing education when explaining why biceps-related pain can feel deep and intra-articular rather than muscular. Anatomical accuracy verified by SciePro's Medical Advisory Board.
