Mild pain and swelling may interfere with normal daily activities, such as putting on a coat. The Shoulder Joint By : Gan Quan Fu, PT, MSc. When the arm is raised, the subacromial space narrows, which can result in impingement of the supraspinatus muscle tendon leading to an inflammatory response. • The joint is sensitive to pain, pressure, excessive traction, and distension. (Netter, 2010) References:Dutton,M. Classes. The coracoacromial ligament is clinically important as it prevents superior dislocation of the humeral head of the shoulder joint. Here we will look closer at shoulder anatomy, focusing on the ligaments and joint capsule. The scapula, humerus, and the clavicle are the three bones that form the shoulder joint. Tears in the AC ligament and the nearby coracoclavicular ligaments, which connect the shoulder blade to the clavicle, cause the collarbone to dislocate. Several ligaments make up parts of the joint capsule, and these ligaments are important in keeping the shoulder joint in proper position. Follow.

Users Options. Log in Sign up. This condition is commonly known as a shoulder separation. Test. Stability is provided mainly by ligaments, tendons and muscles; the bones and capsule are of secondary importance. The shoulder joint is formed by the articulation of a large round head of the humerus with the relatively shallow glenoid cavity of the scapula.

Shoulder reconstruction is a surgical procedure performed in patients with shoulder instability to improve stability, restore the function and prevent recurrent dislocations of the shoulder joint. The fibers of the coracohumeral ligament are arranged in a helical fashion so that they unwind and lengthen during external rotation of the humerus. Gravity. Patients with impingement syndrome often complain of pain when their arms are raised (this is particularly common in mechanics and manual labourers who work with their arms overhead). A ligament is a band of fibrous connective tissue that joins two bones forming a joint. Acromioclavicular Joint Sprain The acromioclavicular joint is supported by the acromioclavicular ligament and the coracoclavicular ligament at the outside end of the collarbone near the shoulder.
