Cock-Up Splint is used for which condition?

• A. Wrist drop
• B. Radial nerve injury
• C. Post polio residual paralysis
• D. Clubfoot

Answer: (A)

A cock-up splint is designed to hold the wrist in slight extension, stabilizing the wrist so the fingers can flex and grip more effectively. This position counteracts wrist drop, which occurs when the extensors (often from radial nerve palsy) are weak or paralyzed. By keeping the wrist extended, the splint prevents excessive flexion, reduces functional difficulty with grasp, and supports hand use during recovery. It isn’t used for clubfoot (a foot deformity treated with foot braces and casts) and, while wrist involvement can occur in post-polio residual paralysis, the splint’s primary purpose is to stabilize the wrist when extension is compromised.
