Fracture is one of the common injuries in children, mostly caused by trauma and disease. The exact time a child can recover from a fracture in the arm is related to the extent of the child’s injury and the fracture displacement. If a child has a forearm fracture, clinical recovery can be achieved in about three weeks. If a child has an ulnar radius fracture with a large fracture displacement, he or she can resume normal activities of the upper limb in about eight weeks by giving external fixation such as manual repositioning, plaster brace or brace. Avoid strenuous activities during the fracture recovery period to avoid fracture displacement and perform active functional exercises under the guidance of a physician. During the fracture healing period, eat more calcium-containing foods, such as milk and kelp soup, which are helpful in promoting fracture healing. Children do not need to take medication, and regular X-ray examinations at the hospital to check the location and healing of the fracture are sufficient.
