Which of the following conditions is least likely to require a wrist cock-up orthosis?

• A. Carpal tunnel syndrome
• B. Shoulder dislocation
• C. Wrist fracture
• D. Post-surgical wrist condition

Answer: (B)

Wrist cock-up orthosis immobilizes the wrist in a neutral position to protect healing tissues and reduce strain around the carpal tunnel. This makes it a common choice for conditions that involve the wrist itself and benefit from stabilized positioning without restricting elbow or shoulder movement.

For carpal tunnel syndrome, keeping the wrist neutral lowers median nerve pressure and can relieve symptoms, so the splint is often used. For a wrist fracture, immobilizing the wrist helps the bones heal in proper alignment. After wrist surgery, the orthosis protects the repair and supports healing.

A shoulder dislocation, on the other hand, is a problem at the shoulder joint. Treating it typically requires immobilization of the arm at the shoulder (such as a sling or shoulder immobilizer), not the wrist. The wrist cock-up would not address the instability or healing needs of a dislocated shoulder, making it least likely to be required in this scenario.
