A 3-year-old boy is brought to the pediatrician by his parents because of swelling and tenderness of his left upper arm. According to the father, the boy was running in the garden when he fell and injured his arm 2 days ago. His mother had been on a business trip the past week. The boy's father and 18-year-old brother had been taking care of the patient during that time. The mother reports that she noticed her son refusing to use his left arm when she returned from her business trip. Both parents claim there is no history of previous trauma. The boy is at the 60th percentile for height and 40th percentile for weight. The patient clings to his mother when approached by the physician. Physical examination shows swelling and bruising of the medial left upper arm and tenderness along the 8th rib on the left side. An x-ray of the arm and chest shows a nondisplaced spiral fracture of the left proximal humeral shaft and a fracture with callus formation of the left 8th rib. Which of the following is the most appropriate next step in management?
