Whether you’re worried your child has a fracture, just got a diagnosis, or need help caring for a cast or splint, get clear next steps for child broken bone first aid, home care, and when to seek urgent medical help.
Tell us whether you’re concerned about a possible break, caring for a newly confirmed fracture, managing a cast or splint, or helping after cast removal. We’ll guide you through what to do for a child’s broken bone based on your situation.
If you notice pain, swelling, bruising, trouble moving a limb, or your child does not want to put weight on an arm or leg, keep the injured area still and supported. Do not try to straighten the limb. Apply a cold pack wrapped in cloth for short periods, and seek medical evaluation. If there is severe pain, obvious deformity, numbness, pale or blue skin, heavy bleeding, or the bone may be sticking through the skin, go to the ER right away.
A limb that looks bent out of shape, shortened, or has an open wound over the injury needs immediate medical attention.
If fingers or toes are cold, pale, blue, numb, or hard to move, the injury may be affecting blood flow or nerves and should be checked urgently.
If your child cannot bear weight, cannot move the arm or leg, or pain is intense even with support and rest, prompt evaluation is important.
Limit movement as much as possible. Support the injured arm against the body or keep the leg in a comfortable position until your child is seen.
If you must move your child, a padded splint can help reduce motion. Place support alongside the limb without forcing it straight, and secure it gently.
Use a cold pack wrapped in cloth for 15 to 20 minutes at a time. Avoid placing ice directly on the skin.
Once a broken bone is confirmed, follow the care plan from your child’s clinician. Keep the cast or splint dry unless you were told it is waterproof, encourage rest, and help your child avoid activities that could cause another injury. Elevation can help with swelling, especially in the first couple of days. Call your child’s care team if pain is getting worse, the cast feels too tight, there is a bad smell, skin irritation, fever, or your child’s fingers or toes look swollen, pale, or blue.
It is common for the arm or leg to feel stiff or weak after the cast comes off. Gentle return to normal movement is often part of recovery.
Your child may need to avoid sports, climbing, or rough play for a period of time even after cast removal. Follow the timeline given by the clinician.
Mild soreness can happen, but persistent pain, swelling, or trouble using the limb should be discussed with your child’s medical team.
Go to the ER if the bone may be sticking through the skin, the limb looks badly deformed, your child has severe pain, cannot feel fingers or toes, the skin is pale or blue, there is heavy bleeding, or you suspect a neck, back, or head injury along with the fracture.
Both can cause pain and swelling, so it is not always possible to tell at home. Signs that raise concern for a fracture include visible deformity, point tenderness over a bone, refusal to use the limb, inability to bear weight, or pain that is significant after a fall or direct hit.
Only splint if needed to keep the area still while getting medical care. Use a firm support padded with cloth, place it alongside the injured limb, and secure it gently above and below the injury without tightening too much. Do not try to straighten the limb.
If fingers or toes become more swollen, numb, cold, pale, blue, or hard to move, seek urgent medical advice right away. A cast that feels too tight should not be ignored.
Some stiffness, weakness, and mild soreness can be normal after a cast is removed. If pain is worsening, your child is not using the limb, or swelling returns, contact your child’s clinician for guidance.
