These exercises are used to increase stability, strength and range of motion of the subscapularis, supraspinatus, infraspinatus, and teres minor muscles within the rotator cuff. [26] Passive exercises include internal and external rotation of the shoulder joint, as well as flexion and extension of the shoulder. [26]
Arthrography of shoulder joint (with or without computed tomography) is performed by injecting contrast below and lateral to the coracoid process to outline the shoulder joint. Axillary pouch of the shoulder can be seen on external rotation, while subscapular (subcoracoid) bursa can be seen on internal rotation of arm. The contrast should not ...
The most important ligament involved in shoulder joint stability is the Inferior Glenohumeral Ligament. During abduction of the arm, the middle and inferior ligaments become taut while the superior ligament relaxes. The radius of curvature of the head of the humerus is greater superiorly than inferiorly, which further stretches these ligaments ...
The shoulder joint is considered a ball-and-socket joint. However, in bony terms the 'socket' (the glenoid fossa of the scapula) is quite shallow and small, covering at most only a third of the 'ball' (the head of the humerus). The socket is deepened by the glenoid labrum, stabilizing the shoulder joint. [1] [2]
The deltoid muscle is the muscle [1] forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle', particularly in other animals such as the domestic cat. Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the anterior or clavicular part (pars clavicularis)
The coracoacromial ligament may impinge and compress rotator cuff muscle or tendon. [3] It may be damaged during a shoulder injury. [4]The attachment of the coracoacromial ligament may be moved from acromion to the end of the clavicle when reconstructing the acromioclavicular joint.
The Spencer technique (also known as the "7 stages of Spencer") is an articulatory technique used in Osteopathic medicine to help relieve restriction and pain at the shoulder. [1] Although variations exist, normally 7 steps are included. [2] Indications for the Spencer technique include adhesive capsulitis. [3] The following is a common ...
The face pull is a weight training exercise that primarily targets the musculature of the upper back and shoulders, namely the posterior deltoids, trapezius, rhomboids, Latissimus dorsi as well as the biceps. [1] The face pull is considered an important exercise for shoulder health and stability. [2]
