Abstract: A multi-function hand splint for immobilizing a hand, wrist, and distal forearm of a user includes a sleeve made of a semi-rigid material. The sleeve includes an elongate shell of substantially C-shape with the opening of the C-shape located along the M-L plane of the forearm. This shell includes a dorsal shell portion and a volar shell portion. Extending from the dorsal shell portion is a dorsal hood having a metacarpal hood portion and a phalanx hood portion. The metacarpal hood portion forms a dorsiflexion angle of between 60.degree. to 80.degree. with the axis of the forearm so that a comfortable maximal dorsiflexion of the wrist is achieved. The metacarpal hood portion also forms a hood angle of between 75.degree. to 90.degree. with the phalanx hood portion. A palm arch supports extends from the volar shell portion in order to maintain the hand in the dorsal hood with the wrist in dorsiflexion and the metacarpal-phalangeal joints at an angle greater than about 90.degree. to 105.degree..
