Discontinue the Splint Now
At 3 weeks post-injury, this 11-year-old boy should discontinue the DonJoy splint immediately and return to normal activities without further follow-up or repeat radiographs. 1
Rationale for Immediate Discontinuation
Buckle (torus) fractures of the distal radius are inherently stable compression injuries that require only brief immobilization. The evidence overwhelmingly supports 3 weeks as the appropriate duration:
- Current best practice is 3 weeks of removable splinting - Multiple systematic reviews and prospective studies confirm this timeframe is sufficient for healing without complications 1, 2
- Your patient has already completed this recommended duration
- All buckle fractures heal without complications when managed with brief immobilization 3
No Further Medical Intervention Needed
Do not schedule fracture clinic follow-up and do not obtain repeat radiographs. 1, 4
The evidence is clear on this point:
- Serial radiographs do not change clinical outcomes for buckle fractures 3
- Follow-up visits represent unnecessary healthcare utilization - one audit showed 58% of patients received unnecessary fracture clinic appointments 4
- Once the diagnosis is confirmed initially, no further imaging is required 1
Patient/Family Instructions
Provide the following guidance at splint discontinuation:
- Resume normal activities immediately, including sports
- Expect full return of wrist function
- No activity restrictions are necessary
- Pain should be minimal to absent at this point
- Contact only if new concerning symptoms develop (which is exceedingly rare)
Common Pitfalls to Avoid
The main error in buckle fracture management is over-treatment:
- Continuing immobilization beyond 3 weeks provides no benefit
- Scheduling routine follow-up wastes resources and increases costs - one study calculated $55,890 annual savings by eliminating unnecessary visits 3
- Repeat radiographs expose children to unnecessary ionizing radiation without clinical benefit 3
Practice has shifted dramatically: A 2020 POSNA survey showed 69% of pediatric orthopedic surgeons now use removable splints for 3 weeks or less, compared to only 29% in 2012 5. However, many practitioners still over-treat these injuries due to medicolegal concerns or habit 5.
Why 3 Weeks Is Sufficient
Buckle fractures are compression injuries where the cortex buckles but does not completely break. They are:
- Inherently stable by definition
- Have essentially zero risk of displacement
- Heal reliably without intervention 1, 2
- Do not require the 4-6 weeks typically needed for complete fractures
Your patient at 3 weeks is healed and ready to resume full activities.
