Repair can be performed through an open incision, again requiring detachment of a portion of the deltoid, while a mini-open technique approaches the tear through a deltoid-splitting approach. The latter may cause less injury to muscle and produce better results. [72] Contemporary techniques now use an all arthroscopic approach.
Infraspinatus, 14. Teres minor), 15. Biceps muscle. The rotator cuff (SITS muscles) is a group of muscles and their tendons that act to stabilize the human shoulder and allow for its extensive range of motion. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are: supraspinatus muscle; infraspinatus muscle ...
The infraspinatus is the main external rotator of the shoulder. When the arm is fixed, it adducts the inferior angle of the scapula. Its synergists are teres minor and the deltoid. [4] The infraspinatus and teres minor rotate the head of the humerus outward (external, or lateral, rotation); they also assist in carrying the arm backward. [1]
Empty beer can test: a positive test indicates rotator cuff tear, specifically, supraspinatus muscle tear; Drop arm test: a positive test indicates a supraspinatus tear; External Rotation test: a positive test indicates an infraspinatus or teres minor tear; Lift-off test: a positive test indicates subscapularis pathology

SLAP Tear Repair of SLAP Tear. Repair of SLAP tear. Associated findings within the shoulder joint are varied, may not be predictable and include: SLAP lesion – labrum/glenoid separation at the tendon of the biceps muscle; Bankart lesion – labrum/glenoid separation at the inferior glenohumeral ligament; Biceps Tendon - exclusion of pulley ...
Injury can be described as a ‘mechanical disruption of tissues resulting in pain.' [13] Despite the fact tissues can self-repair, muscle degradation occurs after repeated and prolonged use. [13] Overuse and strain injuries can occur at work, physical activity and daily life. [11]
Animation of the shoulder joint. The muscles shown are subscapularis muscle (at right), infraspinatus muscle (at top left), teres minor muscle (at bottom left) The movement of the scapula across the rib cage in relation to the humerus is known as the scapulohumeral rhythm, and this helps to achieve a further range of movement. This range can be ...
