The protrusion of the shoulder bone in clinical practice may occur due to direct or indirect external force on the shoulder joint, injuring the rostral or acromioclavicular ligaments, resulting in subluxation or complete dislocation of the acromioclavicular joint, which may appear as a protrusion in appearance. The patient can take conservative treatment to correct the dislocation by repositioning the shoulder and elbow, and then fixing the shoulder and elbow band, and applying a golden ointment to the injured area to promote blood circulation and eliminate blood stasis, reduce swelling and pain, or instructing the patient to take blood-boosting medication orally to heal as soon as possible. If the patient has a complete dislocation of the acromioclavicular joint, most of the treatment requires surgery, with incision under anesthesia and fixation with a hook and plate. After surgery, the patient should be instructed to perform early shoulder joint activities to avoid shoulder joint stiffness.
