Intrinsic plus position describes a posture that keeps the intrinsic muscles of the hand in a functional length to protect joints and tendons during immobilization or healing. In this position the MCP joints are flexed while the PIP and DIP joints are extended, and the thumb is abducted. This arrangement tensions the intrinsic muscles (lumbricals and interossei) in a way that supports the extensor mechanism, keeps the MCP collateral ligaments taut, and helps prevent flexion contractures at the metacarpophalangeal joints. It also preserves the web space by abducting the thumb, aiding later pinch and grip.

This posture is especially important in hand rehabilitation after injuries or burns because it reduces the risk of scar contractures and maintains tendon glide and finger alignment, providing a stable, functional resting position.
