Which device is used for radial nerve injury?

• A. Cock-Up Splint
• B. Banjo Splint
• C. Oppen Heimer
• D. Dennis Browne Shoe

Answer: (C)

Radial nerve injury causes wrist drop, so the device chosen should help extend the wrist and fingers to restore function and tendon glide. The Oppenheimer splint is a dynamic extension splint specifically used for radial nerve palsy. It provides a dorsal extension mechanism that assists finger and thumb extension while the wrist is held in a functional position, helping to retrain and preserve extension movements as strength returns. This dynamic support is more suited to rebuilding active extension and functional grasp than a static option.

A cock-up splint, while useful for keeping the wrist in extension to prevent contracture, is static and doesn’t actively assist finger extension, so it’s less ideal for actively addressing radial nerve palsy. The Dennis Browne shoe is for clubfoot, not upper-extremity nerve injuries. The Banjo splint has other indications and doesn’t specifically address the needs of radial nerve palsy.
