Elbow Fractures in Children

Elbow fractures in children

Elbow fractures are common childhood injuries, accounting for about 10% of all childhood fractures. In many cases, a simple fracture will heal well with conservative cast treatment. Some types of elbow fractures, however, including those in which the pieces of bone are significantly out of place, may require surgery. Other structures in the elbow—such as nerves, blood vessels, and ligaments—may also be injured when a fracture occurs and may require treatment, as well.


The elbow is a joint made up of three bones—the humerus, radius, and ulna.

  • The humerus is the upper arm bone between the shoulder and the elbow.
  • The radius is one of the forearm bones between the elbow and wrist. The radius is on the “thumb side” of the forearm.
  • The ulna is the other forearm bone between the elbow and wrist, running next to the radius. The ulna is on the “pinky finger side” of the forearm.

Ligaments on the inner and outer sides of the elbow hold the joint together and muscles surround the joint on the front and back sides. The elbow joint is crossed by three major nerves.

There are several types of elbow fractures, including:

Above the elbow (supracondylar). In this type of fracture, the upper arm bone (humerus) breaks slightly above the elbow. These fractures usually occur in children younger than eight years old. This is the most common type of elbow fracture, and one of the more serious because it can result in nerve injury and impaired circulation.

At the elbow knob (condylar). This type of fracture occurs through one of the bony knobs (condyles) at the end of the upper arm bone. Most occur through the outer, or lateral, knob. These fractures require careful treatment, because they can disrupt both the growth plate (physis) and the joint surface.

At the inside of the elbow tip (epicondylar). At the top of each bony knob is a projection called the epicondyle. Fractures at this point usually occur on the inside, or medial, epicondyle in children from 9 to 14 years of age.

Growth plate (physis). The upper arm bone and both forearm bones have areas of cartilage called growth plates located near the end of the bone. Because growth plates help determine the length and shape of the mature bone, a fracture that disrupts the growth plate can result in arrested growth and/or deformity if not treated promptly.

Forearm. A fracture can occur at the top (head) of the radius bone, causing it to move out of place. Fractures of the tip (olecranon) of the ulna are rare.

Fracture dislocation. A fracture of the ulna associated with a dislocation of the top of the radius at the elbow is called a Monteggia fracture. If the dislocation is not recognized, and only the fracture is treated, it can lead to permanent impairment of elbow joint function.

Open fracture. When a broken bone breaks through the skin, it is called an open fracture. An open fracture may involve damage to the muscles, tendons, and ligaments and take a longer time to heal.


In most cases, elbow fractures in children are caused by:

  • A fall on an outstretched arm
  • A fall directly on the elbow
  • A direct blow to the elbow

Children regularly engage in many activities that put them at risk for injuries to the elbow. Many elbow injuries occur on the playground when children lose their grip on the monkey bars or other equipment. For toddlers, a fall from a lower height can cause an elbow fracture. Elbow fractures may also occur in sports, such as gymnastics or football, or recreational activities such as skateboarding or bicycling.

Wearing protective elbow guards and pads can help reduce the risk of a fracture about the elbow.


No matter where the break occurs, most elbow fractures result in sudden, intense pain in the elbow and forearm. Other common symptoms include:

  • Swelling around the elbow
  • Numbness in the hand, a sign of potential nerve injury
  • Inability to straighten the arm

If your child complains of elbow pain after a fall and refuses or is unable to move his or her arm, it is important to see a doctor immediately.

Doctor Examination

Physical Examination

After discussing your child’s symptoms and medical history, your doctor will perform a careful examination of your child’s arm to determine the extent of the injury. He or she will look for:

  • Tenderness
  • Swelling
  • Bruising
  • Limited movement
  • Change in color in the hand, an indication that circulation has been affected

During the physical examination, your doctor will also check to see whether any injury to the nerves or blood vessels has occurred.

X-rays provide clear images of dense structures such as bone. An x-ray will indicate what kind of fracture has occurred, and whether the bones have angulated or moved out of alignment (displaced). Because a child’s bones are still forming, your doctor may request x-rays of both arms for comparison.
