Supracondylar fractures of the humerus are more common in children, and due to the anatomical characteristics of the elbow joint, postoperative function is also affected to varying degrees, and recovery of joint function takes a relatively long time. Some physicians try to help the child recover joint function sooner by violent means, often resulting in tearing and bleeding of the soft tissues near the elbow joint, which eventually leads to the development of ossifying myositis and aggravates the stiffness of the elbow joint. Therefore, the treatment of supracondylar humerus fractures in children should be cautious, and the postoperative functional exercises should be even more gradual and should not be rushed.
