How the Normal Shoulder Works The rotator cuff tendons (supraspinatus, infraspinatus, teres minor and subscapularis) are just outside the shoulder joint and its capsule. The muscles of the rotator cuff help stabilize the shoulder and enable you to lift your arm, reach overhead, and take part in activities such as throwing, swimming and tennis.

Anatomy Your arm is kept in your shoulder socket by your rotator cuff. These muscles and tendons form a covering around the head of your upper arm bone and attach it to your shoulder blade. There is a lubricating sac called a bursa between the rotator cuff and the bone on top of your shoulder (acromion).

ROTATOR CUFF INJURY AND TREATMENT OPTIONS The rotator cuff can tear as an acute injury such as when lifting a heavy weight or falling on the shoulder or elbow. The shoulder is immediately weak and there is pain when trying to lift the arm. A torn rotator cuff due to an injury is usually best treated by immediate surgical repair. The rotator cuff can also wear out as a result of degenerative changes. This type of rotator cuff tear can usually be repaired but sometimes the tear

Rotator cuff The rotator cuff muscles are important in shoulder movements and in maintaining glenohumeral joint (shoulder joint) stability. These muscles arise from the scapula and connect to the head of the humerus, forming a cuff at the shoulder joint.he tendons at the ends of the rotator cuff muscles can become torn, leading to pain and restricted movement of the arm. A torn rotator cuff can occur following a trauma to the shoulder or it can occur through the wear and tear on tendons, most commonly the supraspinatus tendon found under the acromion.

Rotator cuff problems The shoulder joint is a ball and socket type joint. The top part of the arm bone (humerus) forms a joint with the shoulder blade (scapula). The rotator cuff holds the head of the humerus into the scapula. It also controls movement of the shoulder joint.

- The rotator cuff is a group of four tendons and muscles that converge around the shoulder joint at the top of the humerus, the upper arm bone above the elbow. Together, they form a ''cuff'' that both holds your arm in place and allows it to move in different directions.

- There are four muscle groups in the shoulder: The rotator cuff muscles are the subscapularis, the supraspinatus, the infraspinatus, and the teres minor. They are the primary stabilizers that hold the ball of the humerus to the glenoid socket. The socket is too shallow to offer much security for the humerus.

- The rotator cable extends from the biceps anteriorly to the inferior margin of the infraspinatus tendon posteriorly. This thickening, as described by Burkhart et al. [2], is thought to mechanically protect the weaker avascular crescent region where partial thickness rotator cuff tears most commonly occur.

Shoulder Rotator Cuff Tear. Rotator cuff is the group of tendons in the shoulder joint providing support and enabling wider range of motion. Major injury to these tendons may result in tear of these tendons and the condition is called as rotator cuff tear.houlder arthroscopy is a surgical procedure in which an arthroscope is inserted into the shoulder joint. The benefits of arthroscopy are smaller incisions, faster healing, a more rapid recovery, and less scarring.

Anatomy Your shoulder is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle). Your arm is kept in your shoulder socket by your rotator cuff. These muscles and tendons form a covering around the head of your upper arm bone and attach it to your shoulder blade. There is a lubricating sac called a bursa between the rotator cuff and the bone on top of your shoulder (acromion). The bursa allows the rotator cuff tendons to glide freely when you move your arm.

Subacromial Impingement The rotator cuff lies under the roof of the shoulder (an extension of the shoulder blade known as the acromion ). The space between the acromion and the rotator cuff tendons is filled by the subacromial bursa . This bursa is a fluid filled sac that allows for smooth gliding of the rotator cuff under the acromion with overhead movements of the shoulder.

Together, they form a ''cuff'' that both holds your arm in place and allows it to move in different directions.ost rotator cuff tears develop gradually. But they also can happen suddenly -- you might feel a pop, intense pain, and weakness in the arm. To diagnose a rotator cuff tear, your doctor will give you a thorough physical exam.

Anatomy When one or more of the rotator cuff tendons is torn, the tendon no longer fully attaches to the head of the humerus. Most tears occur in the supraspinatus muscle and tendon, but other parts of the rotator cuff may also be involved. In many cases, torn tendons begin by fraying.

Orthopedics Rotator cuff problems. The rotator cuff is a group of muscles and tendons that attach to the bones of the shoulder joint, allowing the shoulder to move and keeping it stable. Rotator cuff tendinitis refers to irritation of these tendons and inflammation of the bursa (a normally smooth layer) lining these tendons.

Rotator cuff Muscles composing rotator cuff. The supraspinatus muscle fans out in a horizontal band to insert on the superior and middle facets of the greater tubercle. The greater tubercle projects as the most lateral structure of the humeral head. Medial to this, in turn, is the lesser tuberosity of the humeral head. The subscapularis muscle origin is divided from the remainder of the rotator cuff origins as it is deep to the scapula. The four tendons of these muscles converge to form the rotator cuff tendon.

What's it like: To have your rotator cuff repaired Your arm is kept in your shoulder socket by your rotator cuff, a group of muscles and tendons that help the shoulder rotate and move. These muscles come together as tendons to form a covering around the head of the humerus, the upper arm bone.

Muscles of the Shoulder The rotator cuff consists of four muscles: supraspinatus, infraspinatus, subscapularis, and teres minor. Each of these muscles has its origin on the scapula and inserts around the head of the humerus. The tendons of these muscles surround and support the humerus while the contraction of the muscles rotates, adducts, or abducts the humerus. Surrounding the rotator cuff muscles are many groups of muscles that work together to produce the various movements of the shoulder.

Rotator Cuff Tendonitis The rotator cuff is a group of muscles which originate from the shoulder blade and attach to the upper arm bone (humerus) via the rotator cuff tendons (figure 1). Collectively, the rotator cuff act to provide stability to the shoulder joint and assist with elevation and rotation movements of the shoulder.

Rotator Cuff Disorders - Topic Overview The bones are held together by muscles, tendons, and ligaments. The rotator cuff keeps the upper arm bone in the shoulder socket and lets you raise and twist your arm. The shoulder is a ball-and-socket joint. The ball at the top of the upper arm bone fits into the socket of the shoulder blade.This socket is shallow, which lets you move your arm in a wide range of motion. But it also means that the muscles and tendons of the rotator cuff have to work hard to hold the bones in place.he rotator cuff keeps the upper arm bone in the shoulder socket and lets you raise and twist your arm.

The Rotator Cuff - S.I.T.S Muscles View All. Your rotator cuff in your shoulder is made up of four muscles. These individual muscles combine at the shoulder to form a thick cuff over this joint. The rotator cuff has the important job of stabilizing the shoulder as well as elevating and rotating the arm. Each muscle originates on the shoulder blade, or scapula, and inserts on the arm bone, or humerus.

Rotator Cuff Tears, Injuries and Treatments Rotator Cuff Tears, Injuries and Treatments. The rotator cuff is made up of four muscles whose tendons come together to form a covering around the head of the humerus (upper arm bone) and top of the shoulder. Together with the joint capsule, ligaments and labrum, the rotator cuff muscles are important dynamic stabilizers and movers of the shoulder joint. As the name implies, the rotator cuff functions to internally and externally rotate the shoulder and lift the arm.
