Splinting
Sugar tong, posterior slab, and what must be checked.

At a glance
A splint is temporary protection that must hold reduction, allow swelling, and leave a neurovascular exam you can trust. Bad molding and circumferential constriction create the complications the fracture did not.
Technique pointers
- Choose the construct for the injury (sugartong for many distal radius / forearm; posterior slab ± U-slab for ankle; coaptation for humeral shaft)
- Pad bony prominences; mold while maintaining reduction — do not just wrap
- Leave room for swelling; avoid circumferential casts acutely when swelling risk is high
- Document NV status before and after
- Give clear return precautions for pain out of proportion, color change, and progressive numbness
Decision-making
If the reduction depends on the splint, obtain post-splint films. If pain escalates after immobilization, loosen and re-examine for compartment syndrome rather than adding opioids and hope.
Unstable patterns need a follow-up plan measured in days, not “see someone eventually.”
High-yield / exam
- Mold > layers
- NV exam before and after
- Allow for swelling acutely
- Post-reduction / post-splint imaging when alignment matters
