In the functional position used for splinting or immobilization, which combination best describes wrist and thumb positions?

• A. Flexion, and abduction of the thumb
• B. Extension, and abduction of the thumb
• C. Flexion, and adduction of the thumb
• D. Flexion, and adduction of the thumb

Answer: (D)

In immobilization, the goal is to hold the hand in a resting, stable posture that minimizes tissue tension and preserves grip when you return to function. Positioning the wrist in a slight flexion helps reduce strain on the dorsal structures and keeps the hand from tight extensor tendon pulling during splint wear. Having the thumb adducted toward the palm keeps the first web space compact and the thumb tucked into a natural resting place, which supports a stable, comfortable hand position during immobilization. If the wrist were extended or the thumb were abducted, the hand would be more open and the position could place unnecessary strain on tissues or make the splint less comfortable or effective. So the combination of wrist flexion with the thumb adducted aligns with a functional, stable resting posture for splinting.
