For a child with a confirmed distal radius buckle (torus) fracture, should a removable short‑arm splint be used for three weeks?

Removable Short-Arm Splint for Pediatric Distal Radius Buckle Fractures

Yes, a removable short-arm splint worn for 3 weeks is the appropriate treatment for a child with a confirmed distal radius buckle (torus) fracture, without the need for routine follow-up or repeat imaging.

Evidence-Based Recommendation

The current evidence strongly supports using removable splinting over traditional casting for these inherently stable fractures 1. A 2022 systematic review confirms that torus fractures should be managed with a removable splint supplied at initial presentation and worn for 3 weeks, with no need for fracture clinic follow-up or repeat radiological imaging once adequate information is provided 1.

Key Supporting Evidence

Functional Outcomes:

• Children treated with removable splints demonstrate better physical functioning at 14 days post-injury compared to those in casts 2
• Splinted children experience less difficulty with activities of daily living, particularly bathing 2
• Return to activities occurs faster with splints: 1.77 times more likely at 3 weeks and 1.44 times more likely at 4 weeks 3

Clinical Healing:

• All torus fractures heal clinically within 3-4 weeks regardless of immobilization method 3
• No refractures have been reported with splint treatment 2
• These are inherently stable fractures with extremely low complication risk 4

Pain Considerations (Important Caveat)

Splints may result in slightly higher pain scores in the first week:

• At 3 days: mean difference of 1.00 points higher 3
• At 1 week: mean difference of 1.46 points higher 3

However, this minor early discomfort is offset by superior functional outcomes and faster return to normal activities. Pain differences resolve after the first week.

Practice Trends

A dramatic shift in practice has occurred: in 2020,69% of pediatric orthopedic surgeons preferred removable wrist splints compared to only 29% in 2012 5. Younger practitioners (in practice <20 years) show even higher adoption rates at 76% 5.

Clinical Algorithm

1. Confirm diagnosis of isolated distal radius buckle/torus fracture on radiograph
2. Apply removable wrist splint in the emergency department
3. Instruct for 3 weeks of splint wear
4. Provide clear written information to patient/family about the stable nature of the injury
5. No routine follow-up required
6. No repeat imaging needed
7. Safety-net advice: return only if severe pain develops or concerns arise

Cost and Resource Benefits

This approach represents significant resource savings for patients, families, and healthcare systems 1. Material costs for splints are approximately 10 times lower than traditional casting 4, and elimination of unnecessary follow-up visits reduces healthcare burden substantially 6.

Common Pitfall to Avoid

The main concern preventing broader adoption is fear of misdiagnosis 5. Ensure accurate radiographic confirmation that the fracture is truly a buckle/torus pattern before implementing this streamlined approach. If any doubt exists about fracture stability or pattern, consider standard immobilization with follow-up.
