Broken bones (or fractures) have an amazing ability to heal, especially in young people. New bone forms within a few weeks of the injury. Depending on the exact bone and type of break, full healing can take just a few months.

How Do Casts & Splints Help Broken Bones Heal?

Casts and splints hold broken bones in place while they heal. New hard bone forms in about 3–6 weeks, and the cast or splint usually can come off.

After the cast or splint comes off, you may not be ready to return to gym and sports right away. Your muscles may be weak or stiff, and your bone may need more time to get stronger.

Your doctor may recommend physical therapy to help with healing. Often, just time, stretching, and regular activity is enough for healing.

How Can I Help My Bone Heal?

To help your broken bone heal:

• Eat a healthy diet that includes plenty of calcium and vitamin D.
• Take good care of the cast or splint.
• Rest and/or do any exercises that your doctor recommends.

Broken bones are common in teens. Most breaks heal well, and within a few months you'll be back to all the things you did before the injury.
