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 having a dorsal shell portion and a volar shell portion. Extending adjustably 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 adjustably 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.. A thumb opening is provided between the dorsal hood and palm arch support so that the thumb of the user extends therethrough and all joints of the thumb are free to move. Suitable straps are preferably used to hold the sleeve in radial abutment with the hand, wrist, and distal forearm of the user.
