Radius and Ulna Shaft Fracture

This describes a fracture of both forearm bones (radius and ulna) together in an adult, typically stabilized with surgery given the load these two bones share with everyday arm rotation.

This page explains how a radius and ulna shaft fracture is commonly managed, in plain language, based on Dr. Kee's typical approach to this injury.

Body Region

Treatment

Expected Bone Healing
About 8–12 weeks or longer.

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 personal treatment plan — always follow the specific instructions given to you by Dr. Kee's office.

What Is This Injury?

This describes a fracture of both forearm bones (radius and ulna) together in an adult, typically stabilized with surgery given the load these two bones share with everyday arm rotation.

Bone Doc Tip

Restoring radial bow and forearm rotation is central to functional recovery.

How Is It Treated?

This fracture is generally treated with surgery to stabilize the bone while it heals. Your surgeon will explain the specific technique planned for your fracture pattern.

Brace, Cast, Splint, or Sling

A long-arm splint (LAS) for about 2 weeks, then a short-arm cast (SAC) for about 4 more weeks.

Walking or Using the Injured Limb

No weight bearing (NWB) through the arm for about 6 weeks.

For a full explanation of what these weight-bearing terms mean, see our Weight-Bearing Guide.

When Does Motion Begin?

No resistance or strengthening (NRM) through the arm for about 6 weeks.

Physical Therapy

Formal therapy for forearm rotation, wrist/elbow motion, and strength after healing permits.

Follow-Up and Imaging

A follow-up visit around 1–2 weeks to recheck alignment on X-ray, then a 6–8 week X-ray to confirm healing. An optional 6–9 month X-ray may be used to monitor final healing.

Recovery Timeline
Short AnswerRecovery generally moves through protection, motion, weight-bearing, strengthening, and return to activity — at a pace your surgeon sets for your specific fracture.

Every fracture moves through the same general phases, though the exact timing is different for every patient:

1
Injury or Surgery
The fracture occurs, or is surgically stabilized if your surgeon recommends fixation.
2
Early Protection
A long-arm splint (LAS) for about 2 weeks, then a short-arm cast (SAC) for about 4 more weeks.
3
Begin Motion
No resistance or strengthening (NRM) through the arm for about 6 weeks.
4
Progress Use / Weight Bearing
No weight bearing (NWB) through the arm for about 6 weeks.
5
Strengthening
Physical therapy often helps rebuild strength once your surgeon confirms it's safe to begin.
6
Return to Activity
Return to work, school, driving, and sports is guided by your surgeon as healing progresses.
Return to Activity

Work or School: Desk work with restrictions; heavy work after union and functional rotation return.

Sports or High-Risk Activity: Often 3–4 months or longer.

Watch For — Specific to This Injury

Compartment symptoms, neurovascular deficit, infection, loss of alignment, synostosis, or delayed union.

General Warning Signs — When to Call

  • Increasing pain that isn't controlled by your prescribed plan
  • New numbness or weakness
  • Fingers or toes that become pale, blue, cold, or very swollen
  • A cast or splint that becomes excessively tight, wet, damaged, or foul-smelling
  • New drainage, spreading redness, fever, or wound concerns

See our full When to Call page for the difference between routine office contact and emergency evaluation.

Chest pain, shortness of breath, or symptoms of a possible blood clot, or any life-threatening emergency — call 911 or go to the nearest emergency department.

Frequently Asked Questions

How long will I be in a cast, splint, or brace for a radius/ulna shaft fracture?

A long-arm splint (LAS) for about 2 weeks, then a short-arm cast (SAC) for about 4 more weeks.

When can I return to work, school, driving, or sports after a radius/ulna shaft fracture?

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.

Still Have Questions?

Every fracture heals differently. If you have questions about your treatment plan, reach out to Dr. Kee's office.
