the labrum is best retained for stability reasons. When total joint replacement is planned, the entire labrum can be re-sected, which facilitates the release and enlarges the expo - sure of the glenoid. In spite of capsular resection, posterior instability does not occur provided that the dynamic stabilizers are free to work,

Glenohumeral Joint: Ball and socket synovial joint. Large range of mobility however, this range reduces the joint stability mechanisms. Passive stability due to glenoid labrum, joint capsule and associated ligaments. Dynamic stability due to muscles of the rotator cuff as well as the long head of the biceps brachii muscle.

deltoid is a significant contributor to anterior stability in the position of apprehension, with all three heads contributing equally to stabilization (Kido et al 2003). The lateral deltoid is a key muscle restraint to inferior gle-nohumeral instability (Halder et al 2001b). PATHOLOGY Avulsion of the glenoid labrum in the antero-inferior

The force produced through BY deltoid muscle (D)acts at a distance of 3 cm from the center of rotation The force produced by the weight of the arm is estimated to be 0.05 times body weight (BW) and acts at a distance of 30 cm from the center of rotation. The reaction force on the glenohumeral joint (D) may be calculated with

tendon, rotator cuff, long head of biceps, and three deltoid heads. Passive muscle loaded ROM and shoulder stability with an anterior applied external load were evaluated with a repeated measures design with three conditions: intact, 30% anterior glenoid defect, and Latarjet with and without conjoint tendon loading.

hip and knee (Fig. 3). The labrum adds limited stability, but multiple capsular folds and synovial pouches with twice the humeral head volume lead to laxity. Stability is thereby sacrificed for mobility so that the shoulder has the greatest resultant range of motion of any joint in the body. Dynamic function relies on the rotator cuff. It

The stability of the glenohumeral joint is imparted by both static and dynamic mech-anisms. Static stabilisers are the medial and lateral glenohumeral ligaments, and the joint capsule. Dynamic stabilisers consist of five periarticular (cuff) muscles that span the joint. They include the infraspintus, su-praspinatus, subscapularis, and teres minor

the three portions 4). The force lines of the middle deltoid and supraspinatus are similar during shoulder abduction. During abduction, the two muscles can help stabilize the humerus head in a functional concavity formed by the inferior joint capsule5). The posterior deltoid is important for maintaining the dynamic stability of the shoulder

[10‑14]Additionally, the dynamic sling effect of the conjoint tendon is thought to enhance the stability provided by the bone block alone.[10] The Latarjet, as classically described,[9] involves transfer of the coracoid body with its inferior surface fixed to the anterior glenoid vault.
