Growth Plate Fracture or Injury
What is a growth plate in a bone?
Growth plates control how bones grow in children. They are located near joints and are active in children and adolescents. Growth plates disappear once maturity is reached.
What is a growth plate fracture?
A growth plate can be fractured in the same way that a bone can be fractured. Growth plate fractures are common due to the soft and delicate nature of the growth plates. Growth plates do not appear on X-rays since they are not calcified like other bones. Because of this, it may be impossible to detect a growth plate fracture through an X-ray. In adults, traumatic force applied near a joint typically causes a “sprain” to the ligaments. In children is more commonly caused by a disruption (or fracture) through the growth plate. Boys are at a greater risk of fracturing a growth plate than girls, because girls finish growing sooner than boys. Typically the growth plates in the arms and legs close (disappear) at age 14 in girls and age 16 in boys.
What causes a growth plate fracture?
Like fractures in other bones, growth plate fractures most often occur after a traumatic blow to the area. Sports such as football, soccer, gymnastics, or dancing are typical activities during which growth plate fractures occur. Recreational activities such as skateboarding, biking, trampolining, skiing or running can also put children at risk of a growth plate fracture.
What are the symptoms of a growth plate fracture?
Growth plate fractures often occur in the lower legs or forearms. A growth plate fracture can cause nearby joints to feel warm or swell. The fracture can cause pain, especially when pressure is applied to the area. Being unable to put weight on or move the arm or leg can be another symptom of a growth plate fracture. Your doctor will examine X-rays to determine if the bone is fractured and if this fracture goes through a growth plate.
What effect does a growth plate fracture have on children?
Without treatment, even after a fractured growth plate heals, a growth arrest can still occur. A growth arrest can cause the bone to grow unevenly and become crooked. The bone may also stop growing altogether, resulting in a shorter arm or leg. Most growth plate injuries heal after 4-6 weeks of immobilization in a cast. However, there is always a risk that a growth plate fracture could result in premature stoppage of growth of that particular growth plate.
How is a growth plate fracture treated?
The treatment depends on the severity of the injury. Usually the fracture will require a cast or splint until the bone heals properly. As mentioned above, most growth plate injuries heal after 4-6 weeks of immobilization. If the injury is more severe, surgery may be required to make sure that the bone is able to heal. Please see the growth arrest condition page for information on how a growth arrest is treated.
After a growth plate fracture heals, should the child continue to see the doctor to make sure that the bone is growing normally?
In most cases it is impossible to tell at the time of injury if there will be a permanent cessation of growth, either partial or complete. Therefore, it is important for you to bring children back for follow-up visits for 6-12 months after the injury.
