Infraglenoid Tubercle Of The Scapula, Lateral View

Description

Infraglenoid tubercle anatomy anchors the lateral margin of the scapula just inferior to the glenoid cavity, appearing as a roughened bony prominence at the caudal edge of the shoulder joint socket. From this fixed lateral view, the glenoid fossa sits superiorly and slightly anterior, while the scapular neck narrows medially into the body of the blade, emphasizing how close the tubercle lies to the articular rim. The adjacent infraglenoid region blends into the lateral border, with the axillary aspect of the scapula forming the osseous buttress between the torso and the proximal humerus. Small but specific. Clinically, the infraglenoid tubercle is the origin of the long head of the triceps brachii, so its location matters when teaching posterior shoulder pain patterns and when planning posterior approaches that work near the glenoid rim and scapular neck. The lateral scapular perspective is also the one surgeons and radiologists mentally reference when discussing scapular neck fractures, glenoid rim injury, or bony landmarks used in shoulder arthroplasty and stabilization procedures, where millimeters at the socket margin affect anchor placement and fixation. Surface texture is highlighted to separate the tendon footprint from the smoother periarticular bone around the joint surface. Use this illustration for upper limb and shoulder girdle anatomy labs, sports medicine lectures on triceps and scapulohumeral mechanics, or orthopedic manuscripts describing glenoid-related pathology and posterior surgical corridors. It also fits patient-facing education on shoulder blade (scapula) landmarks when explaining where tendon attachments sit around the joint.
