This describes a fracture of both forearm bones (radius and ulna) together in an older child or pre-teen, who has less remaining growth to naturally correct any residual angulation compared with a younger child.
This page explains how a pediatric both-bone forearm fracture (age 10 and older) 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.
This describes a fracture of both forearm bones (radius and ulna) together in an older child or pre-teen, who has less remaining growth to naturally correct any residual angulation compared with a younger child.
Older children have less remodeling potential, so alignment and rotation deserve closer attention.
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 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.
Consider therapy if pronation/supination or elbow/wrist motion is slow to recover.
Weekly alignment X-rays for the first 3 weeks. Older children have less remaining growth to correct angulation, so your surgeon allows less angulation on X-ray than for a younger child with the same injury. A 6-week X-ray then confirms healing and clears the weight-bearing restriction.
Every fracture moves through the same general phases, though the exact timing is different for every patient:
School: School with restrictions; no lifting or fall-risk activity until union.
Sports or High-Risk Activity: Usually 10–14 weeks, with longer refracture precautions for high-risk activity.
Loss of reduction, rotational deformity, neurovascular symptoms, compartment concern, or delayed healing.
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.
