The shoulder that is injured is placed in a sling and shoulder flexion or abduction of the arm is avoided for 4 to 6 weeks after surgery (Brewster, 1993). Avoiding movement of the shoulder joint allows the torn tendon to fully heal. [24] Once the tendon is entirely recovered, passive exercises can be implemented.
The muscles of internal rotation include: of arm/humerus at shoulder. Anterior part of the deltoid muscle [1] Subscapularis [1] Teres major [1] Latissimus dorsi [1] Pectoralis major [1] of thigh/femur at hip [2] Tensor fasciae latae; Gluteus generalis; Anterior fibers of Gluteus meralis; Adductor longus and Adductor brevis; of leg at knee [3 ...
Horizontal abduction and horizontal adduction of the shoulder (transverse plane) Medial and lateral rotation of the shoulder (also known as internal and external rotation). Medial rotation is carried out by the anterior fibres of the deltoid, teres major, subscapularis, pectoralis major and the latissimus dorsi.
Shoulder anatomy, front view Shoulder anatomy, back view. The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [3] These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the shoulder joint, along with humeral abduction. The extrinsic muscles include the biceps, triceps, and deltoid muscles and attach to the coracoid process and supraglenoid tubercle of the scapula, infraglenoid tubercle of the ...
Lateral rotation (in abduction: 95°; in adduction: 70°) Infraspinatus: Infraspinous fossa of scapula Greater tubercle of humerus Teres minor Upper two thirds of lateral border of scapula Greater tubercle of humerus Posterior fibers of deltoid Spine of scapula Middle of lateral surface of shaft of humerus Medial rotation (in abduction: 40 ...
The supraspinatus muscle performs abduction of the arm, and pulls the head of the humerus medially towards the glenoid cavity. [5] It independently prevents the head of the humerus from slipping inferiorly. [5] The supraspinatus works in cooperation with the deltoid muscle to perform abduction, including when the arm is in an adducted position. [5]
External rotation (or extorsion or lateral rotation) is an anatomical term of motion referring to rotation away from the center of the body. The external rotator muscles include: Muscles
