In a resting hand splint, the PIP and DIP joints should be in which position?

Resting in a relaxed, functional posture for the fingers means keeping the PIP and DIP joints in slight flexion. This small amount of bend places the finger joints in a safe length for immobilization: it helps maintain the length of the flexor tendons and the surrounding soft tissues, reduces the risk of contractures developing in the dorsal structures, and supports a balanced tension between the finger flexors and extensors. If the joints were in full extension, the dorsal tissues and extensor mechanisms could tighten over time; neutral could still allow gradual tightening of soft tissues, while hyperextension would place undue stress on the volar plate and ligaments and foster deformities. So, slight flexion at the PIP and DIP is the position that best preserves tendon length and joint health during a resting hand splint.
