After refixation of the upper extremity, the upper extremity is usually fixed in the neutral position of the elbow joint or in the external booth of the shoulder joint. The neutral position of the elbow joint means that the elbow joint is flexed 90 degrees, the forearm is placed on the chest, and the patient’s upper extremity is maintained in this position using a shoulder sling or a triangular scarf or the like. This type of fixation is mainly used for fractures below the shoulder joint, i.e., below the humeral stem. The shoulder abduction brace is used to keep the shoulder joint abducted by about 60 degrees, with a certain amount of internal retraction, internal rotation, and 90 degrees of elbow flexion, with the tip of the thumb on the patient’s side facing the tip of his or her nose. The upper extremity is then fixed in this position using a shoulder abduction brace. This type of immobilization is generally indicated for patients with shoulder-related fractures, such as fractures of the humeral neck, greater tuberosity, humeral head, scaphoid, and so on.
