These deposits are common in rotator cuff tendinopathy and are most frequently found in the supraspinatus tendon (63% of the time), and less frequently in the infraspinatus tendon (7%), subacromial bursa (7%), subscapularis tendon (3%), or in both the supraspinatus and subscapularis tendons at the same time (20%).

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 ...
Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. [2] The pain is typically worse with movement. [2] It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis).
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]
Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus muscle. [1] This can result in pain, weakness, and loss of movement at the ...
Rotator cuff tendinopathy is a process of senescence. The pathophysiology is mucoid degeneration. [4] Most people develop rotator cuff tendinopathy within their lifetime. [5] As part of rotator cuff tendinopathy, the tendon can thin and develop a defect. This defect is often referred to as a rotator cuff tear.
Mucoid degeneration is when fibrous tissue, such as tendon, has less organized collagen, more abundant extracellular matrix, and changes in the cells to act and look more like cartilage cells (chondroid metaplasia). Diagnosis is typically based on symptoms and signs after excluding other possible causes. [2]
An enthesopathy refers to a disorder involving the attachment of a tendon or ligament to a bone. [1] This site of attachment is known as the enthesis (pl. entheses) . If the condition is known to be inflammatory , it can more precisely be called an enthesitis .
