The acromioclavicular (AC) joint is located between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle. The glenohumeral joint, to which the term "shoulder joint" commonly refers, is a ball-and-socket joint that allows the arm to rotate in a circular fashion or to hinge out and up away from the body.
The acromioclavicular joint, or AC joint, is a joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle . [ 1 ]
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle. [1]
These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the glenohumeral 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 ...
Muscle groups such as serratus anterior, trapezius, and rhomboid major/minor need to be strengthened to allow for shoulder function. By stabilizing these muscles there is more alignment which causes a reduction in strain and protects the joints. Glenohumeral exercises are focused around strengthening the rotator cuff muscles.
The shoulder joint, also known as the glenohumeral joint, is the major joint of the shoulder, but can more broadly include the acromioclavicular joint. In human anatomy, the shoulder joint comprises the part of the body where the humerus attaches to the scapula, and the head sits in the glenoid cavity. [1]
The acromioclavicular joint, is the joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle. [1] It is a plane synovial joint. The acromioclavicular joint allows the arm to be raised above the head.
Shoulder arthritis can be one of three types of arthritis in the glenohumeral joint of the shoulder. The glenohumeral joint is a ball and socket joint, which relies on cartilage to move smoothly and to operate normally.
