What is the recommended splinting position for mallet finger?

• A. Flexion
• B. Neutral
• C. Hyperextension
• D. Ulnar deviation

Answer: (C)

Mallet finger happens when the terminal extensor tendon at the DIP joint is disrupted. For healing, the tendon ends need to be kept in a position that lengthens and aligns them, so the splint holds the DIP in extension. This extension, often described as slight hyperextension, maintains the tendon in a lengthened state and prevents the finger from bending, allowing the tendon to reattach and heal properly. If you splint in flexion, the tendon remains shortened and healing is hindered, risking a persistent flexed posture. Neutral does not provide the continuous extension needed to promote tendon healing, and ulnar deviation has no bearing on positioning of the DIP joint for this injury. A dorsal extension (stack) splint is the typical method, worn for several weeks to ensure proper recovery.
