生长板损伤

The growth plate is the area of tissue near the ends of long bones in children and teens that determines the future length and shape of the mature bone. Each long bone has at least two growth plates, one at each end, and they are longer than they are wide. For example, the femur (thigh bone), radius and ulna (forearm), and the metacarpal bones (hands and fingers) are long bones. Once your child’s growth is complete – sometime during adolescence – the growth plates close and are replaced by solid bone. The growth plates are weak areas of your child’s growing skeleton. Because they are even weaker than the nearby ligaments and tendons that connect bones to other bones and muscles, growth plates are vulnerable to injury. Injuries to the growth plate (fractures) can result from a single traumatic event, such as a fall or automobile accident, or from chronic stress and overuse. Children and teens with growth plate injuries often need immediate treatment to prevent problems with bone growth. However, with proper treatment, most growth plate fractures heal without any lasting effect.
