Distal Radius Reduction & Sugartong

Step-by-step reduction and splint that holds.

Aug 15, 2026 · 3 refs

At a glance

A distal radius reduction is only as good as the splint that holds it and the films that prove it. The goal is length, inclination, tilt, and articular congruence — then a sugartong that prevents redisplacement without creating a compartment crisis.

Technique pointers

1. Adequate analgesia / hematoma block as appropriate 2. Recreate the injury slightly, then traction and reduction maneuver for the pattern 3. Mold — not just wrap — while maintaining reduction 4. Sugartong: control forearm rotation; leave room for swelling; check capillary refill and sensation 5. Post-reduction AP and lateral; document parameters 6. Re-check NV status after splinting

Decision-making

If post-reduction films fail parameters for this patient, say so and plan the next step (re-reduction vs operative discussion). A “better than the injury film” reduction can still be unacceptable.

Median nerve symptoms that worsen after reduction need a clear escalation path — do not normalize progressive deficit inside a tight splint.

High-yield / exam

  • Post-reduction films are mandatory
  • Molding matters more than layers of plaster
  • Always re-check neurovascular status
  • Unstable patterns redisplace — follow closely
