Broken Lower Leg in Children: Care Instructions

Lower leg fracture

Overview

Treatment for your child's broken leg will depend on how bad the break is. Your doctor may have put the lower leg in a splint or a cast to allow it to heal or keep it stable until your child sees another doctor. It may take weeks or months for your child's leg to heal. You can help it heal with some care at home.

Healthy habits can help your child heal. Give your child a variety of healthy foods. And don't smoke around your child.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

  • Put ice or a cold pack on your child's lower leg for 10 to 20 minutes at a time. Try to do this every 1 to 2 hours for the next 3 days (when your child is awake). Put a thin cloth between the ice and your child's cast or splint. Keep the cast or splint dry.
  • Follow the cast care instructions the doctor gives you. If your child has a splint, do not take it off unless the doctor tells you to.
  • Be safe with medicines. Give pain medicines exactly as directed.
    • If the doctor gave your child a prescription medicine for pain, give it as prescribed.
    • If your child is not taking a prescription pain medicine, ask the doctor if your child can take an over-the-counter medicine.
  • Help your child keep all weight off of the leg unless the doctor tells you not to. Your child will use crutches to walk.
  • Prop up your child's leg on pillows when your child sits or lies down in the first few days after the injury. Keep the leg higher than the level of your child's heart. This will help reduce swelling.
  • Help your child follow instructions for exercises to keep the leg strong.
  • Have your child wiggle their toes often to reduce swelling and stiffness.

When should you call for help?

Call 911 anytime you think your child may need emergency care. For example, call if:

  • Your child has chest pain, is short of breath, or coughs up blood.
  • Your child is very sleepy and is hard to wake up.

Call your doctor or nurse advice line now or seek immediate medical care if:

  • Your child has new or worse nausea or vomiting.
  • Your child has new or worse pain.
  • Your child's foot is cool or pale or changes colour.
  • Your child has tingling, weakness, or numbness in the toes.
  • Your child's cast or splint feels too tight.
  • Your child has signs of a blood clot in the leg (called a deep vein thrombosis), such as:
    • Pain in the calf, back of the knee, thigh, or groin.
    • Redness or swelling in the leg.

Watch closely for changes in your child's health, and be sure to contact your doctor or nurse advice line if:

  • Your child has a problem with their splint or cast.
  • Your child does not get better as expected.
