Acromioclavicular joint dislocations generally do not heal on their own and require aggressive treatment to promote healing. Acromioclavicular joint dislocation is a subluxation of the joint where the outer end of the clavicle is attached to the acromion, and is most commonly seen in young people as a result of sports trauma. Direct or indirect violence to the shoulder can cause the acromion and scapula to misalign forward, downward, or backward, resulting in dislocation. In patients with mild injuries, an articular head tear may occur, usually without deformity of displacement. In severe patients, ruptures of the acromioclavicular ligament and rostral clavicular ligament may occur. Therefore, acromioclavicular joint dislocations generally do not heal on their own. In addition, it is recommended that patients with acromioclavicular joint dislocation go to the hospital in time, clarify the cause of the disease and then follow the doctor’s instructions for treatment to avoid delaying the condition.
