Various Shoulder Ligaments from the Posterior

Description

Posteriorly, the scapula frames the glenohumeral joint, with the spine of the scapula running transversely toward the acromion and the clavicle coursing anterolaterally from the acromioclavicular region. Across the posterior aspect of the joint capsule, the fibrous capsule blends with the labral margin of the glenoid and surrounds the humeral head at the anatomical neck, while capsular thickenings corresponding to the superior, middle, and inferior glenohumeral ligaments are oriented from the glenoid rim toward the proximal humerus. Inferior to the acromion, the humeral head sits lateral to the glenoid fossa, and the relationship to the adjacent ribs and thoracic wall is apparent. Clear bony landmarks. A posterior ligament-focused view matters because capsulolabral pathology often declares itself on this side, and the clinician has to think in terms of restraint patterns rather than isolated bands of connective tissue. Posterior capsular tightness and posterior-inferior capsule contracture can drive a glenohumeral internal rotation deficit, a setup for internal impingement in overhead athletes and for abnormal translation that contributes to posterior shoulder pain. The same anatomic corridor underlies common surgical decision-making in posterior labral repair, where portal placement and anchor trajectory depend on appreciating the glenoid rim, humeral head version, and the capsular attachment zone. Orthopaedic and sports medicine teaching sessions use this plate to explain static stabilizers alongside rotator cuff tendon anatomy, even when the cuff is not the primary emphasis. It also fits anatomy lab practicals on the shoulder girdle, preoperative planning graphics for posterior instability, and textbook figures contrasting anterior versus posterior capsular reinforcements around the humeral joint.
