Children with distal humerus fracture can be treated without surgery if the symptoms are mild, but if there is obvious dislocation or vascular and nerve injury, surgery is needed. It is recommended to go to the hospital to improve the diagnosis of X-rays and other tests, and then according to the specific condition and the doctor’s advice for detailed treatment. Children with distal humerus fracture, if there is no obvious dislocation, no obvious vascular and nerve injury, stable fracture, can be treated conservatively with cast immobilization. However, if the distal humerus fracture has obvious dislocation, or is accompanied by vascular and nerve injuries, or is an unstable fracture such as a comminuted fracture, surgical exploration and internal fixation need to be considered. Adjunctive treatment such as suspension and splinting can be performed after surgery. Generally, humerus fracture can be active after 4-8 weeks, if the bone scab grows well, patients should follow the doctor’s instructions to carry on the activity of functional exercise. Avoid ossified myositis. Normally, it is recommended to take more rest, avoid spicy and stimulating food in diet, be light and nutritious, and develop good living habits.
