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.
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.
Short AnswerA quick explanation of what a radius/ulna shaft fracture is and why it's treated the way it is.
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.
How Is It Treated?
Short AnswerSurgery is generally recommended to stabilize this fracture.
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
Short AnswerSee the type of immobilization typically used for this fracture, and about how long it's worn.
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
Short AnswerFind the general weight-bearing or limb-use status that typically applies to this fracture.
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?
Short AnswerSee roughly when motion is typically introduced for this fracture.
No resistance or strengthening (NRM) through the arm for about 6 weeks.
Follow-Up and Imaging
Short AnswerWhat follow-up visits and imaging typically look like for this fracture.
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
Short AnswerGeneral guidance on when patients typically return to normal activities.
Your surgeon will guide when it's safe to return to work, school, driving, sports, or other activities based on your healing and this specific fracture. Follow the instructions given specifically to you.
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?
Short AnswerIt depends on the specific immobilization used for this fracture — see the typical duration below.
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?
Short AnswerThis is set individually based on your healing, not a fixed calendar date.
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.
