Swan Neck Splint is typically used for which scenario?

• A. Arthritis with actively correctable deformity
• B. Arthritis when actively correctable
• C. Arthritis when passively correctable
• D. For mallet finger injuries

Answer: (C)

The main idea is managing a flexible swan neck deformity by controlling the joint that tends to hyperextend. A swan neck splint is used when the arthritis-related deformity is passively correctable, meaning the finger can be realigned with external help but it tends to revert to hyperextension in use. The splint holds the PIP joint in slight flexion, which prevents PIP hyperextension and allows the rest of the finger (MCP and DIP) to move normally. This approach reduces strain on the dorsal structures and helps restore balance in the finger’s extensor mechanism while the deformity remains reducible. If the deformity were actively correctable by the patient, the splint is less necessary, and for mallet finger you’d use a DIP extension device instead.
