What splint is commonly used to rest the wrist in CTS?

• A. Neutral-position wrist cock-up splint
• B. Thumb spica splint
• C. Dorsal blocking splint
• D. Wrist extension splint

Answer: (A)

Resting the wrist in a neutral position reduces pressure within the carpal tunnel, which helps relieve median nerve irritation in carpal tunnel syndrome. A neutral-position wrist cock-up splint holds the wrist in a neutral (often with a touch of slight extension) while supporting the hand, effectively immobilizing the wrist to prevent movements that increase tunnel pressure. This targeted positioning minimizes the forces across the carpal tunnel during rest and activities that trigger symptoms, making it the most appropriate choice for CTS management.

Other splints either immobilize other joints or place the wrist in a posture that can worsen CTS symptoms: a thumb spica restricts thumb movement and isn’t aimed at reducing carpal tunnel pressure; a dorsal blocking splint is used after flexor tendon injuries to control finger motion; a wrist extension splint positions the wrist in extension, which can increase carpal tunnel pressure and exacerbate symptoms.
