Signs of a broken arm in a child: what to do?

A broken arm (fracture) is a common childhood injury, often from a fall or direct blow. Recognizing the signs and knowing what to do can help prevent further damage and reduce pain.

What is happening?

A fracture is a crack or break in one of the bones of the arm: the humerus (upper arm), radius or ulna (forearm). In children, bones are softer and may break in patterns different from adults. The goal is to keep the arm still and get medical help.

Emergency warning

Call your local emergency number immediately if:

• The arm is visibly deformed or bent at an odd angle.
• Bone is sticking out through the skin (open fracture).
• There is severe bleeding that does not stop with pressure.
• The child is unresponsive, confused, or has trouble breathing.
• The hand or fingers are pale, blue, cold, or numb (signs of poor circulation).

Signs of a broken arm

• Severe pain that worsens with movement.
• Swelling, bruising, or tenderness over the bone.
• Inability to move the arm normally or reluctance to use it.
• Visible deformity or shortening of the arm.
• A snapping or grinding sensation at the time of injury.
• In young children, crying when the arm is touched or refusal to use the arm.

What to do first

1. Keep the child calm and still. Do not move the arm unnecessarily.
2. Support the arm. Use a sling made from a triangular bandage or a piece of cloth, or gently place padding around the arm. Do not try to straighten or realign the bone.
3. Apply a cold pack. Wrap ice or a cold pack in a cloth and apply for 15-20 minutes to reduce swelling. Do not put ice directly on the skin.
4. Control bleeding if present. For an open fracture, cover the wound with a clean cloth and apply gentle pressure around the wound, not directly on the bone.
5. Do not give food or drink. Surgery may be needed, and an empty stomach is safer for anesthesia.
6. Seek medical care. Take the child to an emergency department or urgent care for evaluation. If you are unsure, call your doctor or emergency services for advice.

What NOT to do

• Do not try to push the bone back into place.
• Do not give the child anything to eat or drink.
• Do not apply heat to the injury.
• Do not ignore the injury even if the child seems to calm down; fractures can still be present.
• Do not remove any object that is stuck in the wound.

When to seek professional care

Any suspected broken arm should be evaluated by a healthcare professional. Seek emergency care immediately for the warning signs above. Otherwise, contact your pediatrician or go to an urgent care center promptly.

What to monitor

Watch for increased swelling, changes in skin color (pale, blue, or mottled), numbness or tingling in the fingers, and increased pain. These may indicate problems with circulation or nerves and require immediate medical attention.

How to prevent broken arms

• Ensure children wear appropriate protective gear for sports and activities.
• Supervise play on playgrounds and use safety equipment.
• Childproof homes to reduce fall hazards.
