The beak lock tendon is located between the beak process of the shoulder joint dislocation and the neck. This tendon plays a very important role in maintaining the reliability of shoulder joint dislocation and ensuring the stability of the acromioclavicular joint. When 1/3 of the neck is fractured and the acromioclavicular joint is dislocated, it is necessary to repair the beak lock tendon to maintain the reliability of the acromioclavicular joint and the fracture, prevent the occurrence of complications, and coordinate with the movement of the neck during shoulder joint dislocation exercises. The probability of ligament rupture is not high, usually caused by injury during clavicle fracture.

The beak lock tendon originates from the beak, and is divided into the medial conoid tendon and the lateral trapezoid tendon on both sides of the neck. The beak lock tendon is of great significance for maintaining the stability of the neck and ensuring the normal function of the acromioclavicular joint. Acromioclavicular joint III-type dislocation and fractures on both sides of the neck often coexist with beak lock ligament injury and rupture. The rupture of the beak lock ligament should be treated surgically. 1. For fresh injuries, perform reduction and internal fixation of clavicle fracture (acromioclavicular joint dislocation) and at the same time, perform beak lock tendon suture. 2. For old injuries, perform reduction and internal fixation of clavicle fracture (acromioclavicular joint dislocation) and at the same time, perform beak lock tendon reconstruction. The treatment effect of recent injuries is relatively good, therefore, for such injuries of the shoulder, it is necessary to seek medical attention immediately.

For patients with beak lock ligament injury, the first thing to do is to limit repeated shoulder lifting activities. Because during the process of lifting the shoulders, it will cause the injured beak lock tendon to be stretched, resulting in increased swelling and pain, which is not conducive to the repair of the beak lock tendon. After the injury, it is best to bend the elbow of the affected side to 90 degrees, perform suspension training at the chest, and limit the movement of shoulder joint dislocation. Generally, after the injury, suspension training should be performed for 3-4 weeks to give full play to the characteristics of repairing the injured tendons.

And it can be used externally with the活血化瘀药膏, as well as the treatment of活血化瘀 both internally and externally, to promote the dispersion of blood stasis and swelling after the injury of the beak lock ligament, which is beneficial for the repair of tendons. Generally, after 3-4 weeks of suspension training, one can gradually perform exercises to dislocate the shoulder joint, thereby repairing the normal weight-bearing and flexion-extension activities of the affected limb.
