There is no particularly effective treatment for rotator cuff injuries in Chinese medicine. The choice of Western medical treatment depends on the type of rotator cuff injury and the duration of the injury. The acute phase of rotator cuff contusion, partial rupture or complete rupture is generally treated with non-surgical therapy. Treatment of rotator cuff contusion: rest, suspension with a triangular scarf, braking for 2-3 weeks, and local physical therapy to eliminate swelling and relieve pain. 1% lidocaine plus corticosteroids can be used for intracapsular injection into the subacromial bursa or glenohumeral joint for those with severe pain. Acute phase of rotator cuff rupture: supine position, zero-position traction of the upper limb, i.e., skin traction of the upper limb at 155° each in the abduction and front supination position for 3 weeks, traction with bedside physical therapy, after 2 weeks, intermittent release of traction 2 to 3 times a day, functional exercises of the shoulder and elbow to prevent joint stiffness, also can be changed to zero-position shoulder herringbone cast or zero-position brace fixation after 1 week of bedside traction to facilitate downward movement. Zero-position traction helps the rotator cuff tendons to repair and heal under low tension, and also helps to use the gravity of the limb to promote the rehabilitation of the glenohumeral joint after the removal of traction. Indications for surgical treatment: large rotator cuff tears, rotator cuff tears for which non-surgical treatment is ineffective, and cases with a combination of subacromial impingement factors. Reconstruction. In subacromial impingement syndrome, subacromial plication is feasible.
