Omar Faiz Simon Blackburn and David Moffat. 2011 Blackwell Publishing Ltd. Published 2011 by Blackwell Publishing Ltd. See Figs. 38.3 39.1 and 39.2. Type the shoulder is a synovial ball and socket joint which permits multiaxial movement. It is formed by the articulation of the humeral head with the shallow glenoid fossa of the scapula see p. 77 . The glenoid is slightly deepened by a fibrocartilaginous rim - the glenoid labrum. Both articular surfaces are covered with hyaline cartilage. The capsule of the shoulder joint is lax permitting a wide range of movement. It is attached medially to the margins of the glenoid and laterally to the anatomical neck of the humerus except inferiorly where it extends to the surgical neck. The capsule is significantly strengthened by slips from the surrounding rotator cuff muscle tendons. Stability is afforded by the rotator cuff and the ligaments around the shoulder joint. The latter comprise three gleno-humeral ligaments which are weak reinforcements of the capsule anteriorly a coraco-humeral ligament which reinforces the capsule superiorly and a cora-coacromial ligament which protects the joint superiorly. The main stability of the shoulder is afforded by the rotator cuff. The cuff comprises subscapularis supraspinatus and together .
