We may often hear rotator cuff damage in our daily lives, so what is rotator cuff ?
Rotary cuff is not a sleeve, but a general term for tissues, which includes tendon tissues covering the anterior, upper and posterior sides of the shoulder joint, such as the subscapularis, supraspinatus, infraspinatus , and teres minor.
rotator cuffs meet people's needs for shoulder flexibility and stability. The movement of these tissues together leads to the rotation and lifting of the shoulder joint, and also stabilizes the humeral head on the labrum of the scapula, playing an extremely important role in maintaining the stability of the shoulder joint and shoulder joint activity. When the rotator cuff is damaged, its function will be weakened.
structural complexity determines that it is one of the most common motor injuries in the upper arm. The causes of rotator cuff injury can be roughly divided into acute injuries and chronic degenerative lesions.
Acute injuries mostly occur in young people. When the shoulder joint is violent, damage to the soft tissue around the shoulder joint is prone to occur, such as trauma or after strenuous exercise.
Chronic injuries generally include insufficient blood supply and chronic shoulder impact injuries: ischemia can cause degenerative tendons; repetitive exercises of extremely abduction of the shoulder joint (such as baseball , backstroke and butterfly stroke , weightlifting, racket exercise) can also cause this disease.
