Growth-Plate Fracture

A child's bones are subject to a unique injury called a growth plate fracture. Growth plate fractures can result from a single traumatic event, such as a fall or automobile accident, or from chronic stress and overuse.

Growth plates are areas of developing cartilage tissue near the ends of long bones. They regulate and help determine the length and shape of the mature bone. Because growth plates are the last portion of bones to harden (ossify), they are vulnerable to fracture.

Approximately 15% to 30% of all childhood fractures are growth plate fractures. These often require immediate attention because the long-term consequences may include limbs that are crooked or of unequal length. It is important to seek evaluation and treatment by an orthopedic surgeon experienced in orthopedic trauma.

Growth plate fractures must be watched carefully for long-term results. In some cases, a bony bridge will form across the fracture line that prevents the bone from growing longer or causes the bone to curve. Regular follow-up visits to the doctor should continue for at least a year after the fracture.
