The Glenoid Fossa Of The Scapula From A Lateral View

Description

Seen from the lateral aspect, the scapula rotates to center the glenoid fossa (cavitas glenoidalis), the shallow, pear-shaped articular surface that faces laterally, slightly anteriorly, and superiorly to receive the humeral head. The animation brings the superior and inferior glenoid tubercles into view at the poles of the cavity, with the supraglenoid region continuous with the base of the coracoid process and the infraglenoid region blending into the thickened lateral border of the scapular blade. As the camera tracks around the lateral angle, the neck of the scapula is distinguished from the broader infraspinous and supraspinous fossae posteriorly, clarifying how the articular segment sits on a comparatively thin bony strut. Orientation is explicit. Glenoid morphology drives shoulder stability and is a constant reference point in trauma and reconstruction. Bankart lesions and anteroinferior glenoid bone loss after recurrent anterior dislocation are understood best when you can appreciate where the inferior glenoid rim sits relative to the scapular neck and lateral border, and the sequence of rotation makes that rim easy to localize. The smooth concavity is also where glenoid version and inclination are assessed for total shoulder arthroplasty planning, and the lateral view helps explain why posterior wear patterns change humeral head centering. Use this animation in gross anatomy and kinesiology teaching to anchor glenohumeral joint orientation, or in orthopedic presentations and textbooks to illustrate glenoid rim landmarks relevant to instability repair, Latarjet positioning, and arthroplasty component alignment. It also fits radiology education when paired with axial CT or en face 3D reconstructions to relate imaging measurements back to surface anatomy.
