Rotator cuff (with 11. Supraspinatus, 12. Subscapularis, 13. 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 ...
Rotator cuff tendinopathy is a process of senescence. ... The method currently in favor is to place an anchor in the bone at the natural attachment site, with ...
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 .
The greater tubercle of the humerus is the outward part the upper end of that bone, adjacent to the large rounded prominence of the humerus head. It provides attachment points for the supraspinatus, infraspinatus, and teres minor muscles, three of the four muscles of the rotator cuff, a muscle group that stabilizes the shoulder joint.
The teres minor (Latin teres meaning 'rounded') is a narrow, elongated muscle of the rotator cuff.The muscle originates from the lateral border and adjacent posterior surface of the corresponding right or left scapula and inserts at both the greater tubercle of the humerus and the posterior surface of the joint capsule.
The supraspinatus forms part of the rotator cuff and is one of its most frequently damaged components, whether from acute injury or gradual degeneration. [7] Bad posture and age are leading risk factors, with a high prevalence of asymptomatic partial and full tears, as well as symptomatic syndromes with chronic pain.
In human anatomy, the infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa. [1] As one of the four muscles of the rotator cuff, the main function of the infraspinatus is to externally rotate the humerus and stabilize the shoulder joint.
Thus the words (enthesis and insertion [of muscle]) are proximal in the semantic field, but insertion in reference to muscle can refer to any relevant aspect of the site (i.e., the attachment per se, the bone, the tendon, or the entire area), whereas enthesis refers to the attachment per se and to ligamentous attachments as well as tendinous ones.
