Growth Plate Fractures

Diagnosis

Growth plate fractures can be challenging to identify because the growth plates have not yet hardened into solid bone. Doctors may use the following methods:

• X-rays of both the injured limb and the opposite limb for comparison

• Repeat X-rays in three to four weeks if the fracture is not initially visible, as new bone healing will become apparent

• Advanced imaging for more serious injuries, including:

  • Magnetic resonance imaging (MRI)

  • Computed tomography (CT)

  • Ultrasound

Tenderness over the growth plate area may prompt protective measures even if a fracture is not immediately visible.

Treatment

Treatment depends on the severity and location of the fracture:

• Mild fractures:

  • Cast or splint to immobilize the limb

• More serious fractures:

  • Surgery may be needed if the fracture crosses the growth plate, enters a joint, or is not properly aligned

  • Surgical realignment can improve the chances of the growth plate recovering and continuing normal growth

Follow-up care:

• X-rays may be checked for several years to monitor growth plate healing

• Children may require follow-up visits until their bones have fully matured to ensure proper growth and alignment
