Applying a Rigid Wrist Splint: Step-by-Step First Aid Guide

1. Assess

Check for deformity, swelling, bruising, open wound, neurovascular status (capillary refill, sensation, motor).

2. Position

Place wrist in neutral/functional position (slight extension ~20°, fingers loosely flexed). Put rolled gauze in palm for comfort.

3. Apply Splint

• Place rigid splint (SAM splint, padded board, folded magazine) on palmar/volar side from mid-forearm to base of fingers.
• Pad bony prominences (ulnar styloid, thenar eminence).
• Secure with elastic wrap/tape: distal to proximal, snug but not tight (check capillary refill <3 sec).

4. Thumb Spica (if thumb injured)

Add separate rigid piece along radial side from wrist to thumb tip; secure separately.

5. Elevate

Above heart level to reduce swelling.

6. Seek Medical Care

Urgent evaluation for X-ray, definitive casting/splinting, and follow-up.
