Signs and symptoms of a growth plate injury of the elbow are:

  • Sudden intense pain
  • Swelling
  • Inability to move or straighten the arm normally
  • Numbness in hand or arm
  • Changes in the way the arm bends

When to See a Doctor

See your child’s healthcare provider if your child:

  • Continues to complain of pain after a fall
  • Can’t or won’t move the arm because of pain
  • Limits play time because of a new or old injury
  • Shows changes in the way their arm bends


The most common causes of growth plate injury are:

  • Falls
  • Sports and recreational or playground activities
  • Overuse (repetitive motion)

Other causes include:

  • Child abuse
  • Radiation treatment
  • Extreme cold (frostbite)
  • Certain medicines
  • Genetic (inherited) disorders
  • Infections
  • Other diseases

Diagnosis and Tests

To figure out if your child has a growth plate injury of the elbow, your child’s healthcare provider will ask questions about the injury and look for signs and symptoms of a growth plate injury, including:

  • Swelling
  • Pain
  • Bruising
  • Color changes in the hand
  • Unnatural bends in the bone
  • Reduced movement

To confirm the diagnosis, your child’s healthcare provider may recommend imaging tests such as:

  • X-rays
  • CT scan
  • MRI
  • Ultrasound


The treatment will depend on the type and severity of the injury. It takes three to six weeks for most injuries to heal. In most cases, the elbow’s range of motion will return to normal although the elbow joint may be stiff for a bit. Treatment usually includes:

Splints or casts to hold the bone in place, even if surgery is not needed

Surgery to pin, screw, or wire pieces of bone into place

Exercises or physical therapy (after the injury heals)
