This describes a fracture of both forearm bones (radius and ulna) together. Because younger bones remodel and straighten as they grow, surgeons can accept slightly more angulation in younger children than in older children or adults — your surgeon will confirm whether your child's X-ray alignment is acceptable.
This page explains how a pediatric both-bone forearm fracture (age under 10) is commonly managed, in plain language, based on Dr. Kee's typical approach to this injury.
Every fracture is different. Treatment varies based on the exact fracture pattern, displacement, age, whether surgery is needed, bone quality, other injuries, and how an individual heals. This page is general education, not your child's personal treatment plan — always follow the specific instructions given to you by Dr. Kee's office.

Young children remodel well, but the forearm remains vulnerable to refracture after the cast comes off.
This fracture is generally treated without surgery. Instead, it is protected in a cast, splint, or brace so the bone can heal in a good position on its own.
A long-arm splint (LAS) for about 2 weeks, then a short-arm cast (SAC) for about 6 more weeks.
No weight bearing (limb use) through the arm for about 6–8 weeks.
For a full explanation of what these weight-bearing terms mean, see our Weight-Bearing Guide.
No resistance or strengthening (NRM) for about 8 weeks total.
Usually home motion after cast removal; therapy only if motion does not steadily return.
Weekly alignment X-rays for the first 3 weeks to confirm the bones are staying in a good position for your child's age, then a 6-week X-ray to confirm healing and clear the weight-bearing restriction.
Every fracture moves through the same general phases, though the exact timing is different for every patient:
School: School as tolerated in cast; avoid lifting, wheels, climbing, and playground falls.
Sports or High-Risk Activity: Usually 8–12 weeks; refracture precautions may extend longer.
Loss of alignment, increasing pain, numbness, swelling, compartment concern, or cast problems.
See our full When to Call page for the difference between routine office contact and emergency evaluation.
A long-arm splint (LAS) for about 2 weeks, then a short-arm cast (SAC) for about 6 more weeks.
Your surgeon will guide when it's safe to return to these activities based on how your specific fracture is healing. Follow the instructions given specifically to you.
Every fracture heals differently. If you have questions about your treatment plan, reach out to Dr. Kee's office.
