Clinically, shoulder dislocation can be determined by symptoms and physical examination, imaging examination, etc., as follows: First, clinical symptoms and physical examination: patients with shoulder dislocation will have severe shoulder pain, limited shoulder movement, swelling of the shoulder joint, and the patient’s posture is usually to use the healthy side of the upper limb to support the affected side of the elbow joint, to avoid excessive shoulder joint movement. During the examination, it will be found that the glenoid is empty, and the dislocated humeral head can be touched in the anterior and inferior part of the rostral eminence, and the Dugas sign is positive. Second, imaging examination: through the shoulder joint orthopantomography, it can be found that the glenohumeral joint is dislocated, and the humeral head is usually dislocated below the rostral eminence, and sometimes combined with the humerus and the greater tuberosity avulsion fracture. Once the diagnosis of shoulder joint dislocation is confirmed, timely treatment should be carried out to restore the shoulder joint alignment.
