In a resting hand splint, the MCP joints are positioned at what range of flexion?

Positioning the MCP joints in a resting hand splint at about 35–45 degrees of flexion places the hand in a comfortable, functional posture that helps prevent contractures while preserving balance of the finger extensor and intrinsic muscle systems. At this range, the intrinsic muscles are length-tuned enough to support the hand without causing clawing, and the collateral ligaments around the MCP joints are kept from tightening into hyperextension. This angle also supports good palm arches and tendon gliding when the hand is at rest. If the MCPs were near full extension (0–5 degrees), the hand would sit more in a extended posture, which over time can promote extensor tightness and less favorable intrinsic muscle length. If the MCPs were flexed much more (60–70 degrees or 90 degrees), the hand would resemble an intrinsic-plus or clenched position, which is not ideal for a comfortable resting posture and can limit function and promote stiffness in the IP joints.
