What is a typical positioning goal of a resting (cock-up) splint for the hand?

• A. Wrist in neutral or 12-20 degrees extension
• B. Wrist in full extension
• C. Wrist in full flexion
• D. Fingers fully extended

Answer: (A)

The essential idea is to hold the wrist in a posture that minimizes stiffness and tendon shortening while the hand is at rest. A resting (cock-up) splint achieves this by positioning the wrist in neutral or with a gentle amount of extension—about 12–20 degrees. This places the wrist in a functional alignment that keeps the flexor and extensor tendons at a favorable length, reduces the risk of developing flexion contractures, and helps relieve pressure on neural structures by avoiding full flexion. It also supports a comfortable, relaxed position for the fingers rather than forcing them into extension. Full extension would stress dorsal tissues and isn’t comfortable for long wear, while full flexion would promote shortening of the flexor tendons and more contractures.
