Quick Answer
Paediatric wrist fractures are common, and the distal radius is one of the most frequently injured areas. Because children have substantial remodelling potential, most fractures can heal without surgery. Closer follow-up or fixation may be needed for fractures involving the growth plate, major displacement, an open injury or the joint surface.
Symptoms
- Wrist pain and tenderness after a fall or injury
- Swelling, bruising or reluctance to use the arm
- Visible deformity in more displaced fractures
- In a young child, reduced spontaneous use of the hand or arm
- Numbness, pallor or circulatory change requires urgent assessment
Diagnosis
Examination includes the skin, circulation and nerve function. AP and lateral wrist X-rays identify most fractures. Advanced imaging is rarely required in children, although CT can help define selected complex intra-articular injuries. Salter-Harris classification may be used for physeal injuries.
Treatment
Stable Fractures
POSNA notes that many stable torus/buckle fractures can be treated simply with a removable prefabricated splint. When the fracture pattern and age are appropriate, care can be simpler than prolonged casting and repeated imaging.
Displaced Fractures
Acceptable alignment depends on the child's age, remaining growth and fracture plane. Closed reduction and cast protection may be needed. Selected fractures that cannot maintain reduction, significantly involve the joint surface or growth plate, or have other concerning features may require percutaneous pins or another fixation method.
Why Does the Growth Plate Matter?
The distal radial physis contributes substantially to forearm growth. Growth arrest after physeal injury is uncommon but possible. Follow-up duration therefore depends on fracture type rather than one fixed schedule for every child; higher-risk physeal injuries may need longer radiographic surveillance.
Recovery and Return to Activity
Children generally heal faster than adults, but return to sport should not be based only on cast removal. Pain-free motion, resolution of tenderness, adequate strength and fracture healing are considered. Collision sports or activities with a high fall risk may need a more cautious progression.
When Is Urgent Assessment Needed?
Urgent assessment is needed for an open wound, marked deformity, pale or cold fingers, persistent numbness, very severe pain or rapidly increasing swelling.
Frequently Asked Questions
Does every child need a cast?
No. Some stable torus/buckle fractures can be safely managed with a removable splint once the fracture pattern is confirmed.
Will growth be affected?
Most fractures heal without growth problems. Certain growth-plate injuries carry a small risk of growth disturbance and need a tailored follow-up plan.
Is CT or MRI routinely needed?
No. Standard X-rays are enough for most paediatric wrist fractures. Advanced imaging is reserved for selected complex or intra-articular injuries.
