1. An anatomical structure composed of the tendons of four muscles that control rotation of the shoulder and of parts of the capsule of the shoulder joint.
2. The set of four muscles that control rotation of the shoulder.
a musculotendinous structure about the capsule of the shoulder joint, formed by the inserting fibers of the supraspinatus, infraspinatus, teres minor, and subscapularis muscles, which blend with the capsule and provide mobility and strength to the shoulder joint.
rotator cuffThe tendinous structure around the shoulder joint consisting of the tendons of four adjacent muscles blended with the capsule of the joint. Tearing or degeneration of any of these fibres may cause the common, painful and disabling rotator cuff syndrome in which there may be inability to raise the arm in a particular direction. Surgical repair may be necessary.
rotator cufffour muscles (supraspinatus, subscapularis, infraspinatus and teres minor), which act in synergy at the shoulder joint to facilitate movement and provide stability by maintaining the head of the humerus in the glenoid cavity. In sport, most commonly injured in throwing, swimming and racquet sports with tears, tendonitis or (in young athletes) impingement.
Patient discussion about rotator cuff
Q. what does c4-5 mild central disk bulging impinging upon cervical cord without spinal stenosis or distortion of the cord . mild righ neural foraminal narrowing from uncovertebral joint hypertropy mean
A. Well this basically means there is a very small narrowing of the cervical (your neck area) spinal canal (where the spinal cord is), however the narrowing does not cause any damage to the spinal cord, therefore probably does not cause any major symptoms involving the nerves. The c4-5 bulging part refers to the part in between the two cervical vertebras c4 and c5, in which the disc (a part in the spinal cord) is sliding a bit side-ways, but again, it does not seem to be causing any trouble.More discussions about rotator cuff
