Greenstick or Metaphyseal Fracture of the Distal Radius
A greenstick fracture is a partial break where the bone bends and cracks on one side, similar to a green tree branch — common in growing bones because they are more flexible than adult bone.
This page explains how a greenstick or metaphyseal fracture of the distal radius 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.
Short AnswerA quick explanation of what a greenstick fracture is and why it's treated the way it is.

How Is It Treated?
Short AnswerThis fracture is generally managed without surgery.
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.
Brace, Cast, Splint, or Sling
Short AnswerSee the type of immobilization typically used for this fracture, and about how long it's worn.
A short-arm cast (SAC), typically worn for about 4 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 (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.
When Does Motion Begin?
Short AnswerSee roughly when motion is typically introduced for this fracture.
No resistance or strengthening (NRM) for about 6 weeks.
Follow-Up and Imaging
Short AnswerWhat follow-up visits and imaging typically look like for this fracture.
Weekly alignment X-rays for the first 2 weeks to confirm the bone is healing in good position, then a 6-week X-ray to confirm healing and clear the weight-bearing restriction.
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 short-arm cast (SAC), typically worn for about 4 weeks.
3
Begin Motion
No resistance or strengthening (NRM) for about 6 weeks.
4
Progress Use / Weight Bearing
No weight bearing (limb use) 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 activity as tolerated (PRN).
Return to Activity
Short AnswerGeneral guidance on when patients typically return to normal activities.
Return to activity as tolerated (PRN).
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.
