ABSTRACT:
Apparatus for supporting a patient's hand for surgery, the apparatus including a base plate for placement on an operating table, and an upper plate above the base plate and pivotally coupled thereto by an adjustable ball and socket assembly. The upper plate can be pivoted into any one of a number of operative positions, and the ball and socket assembly can be adjusted to releasably hold the upper plate in a fixed position. A pair of surface defining devices are located near one end edge of the upper plate, one of the devices having a flat upper surface coextensive with the upper surface of the plate, the other device being hingedly mounted to the first device to provide a flat surface coextensive with the upper surface of the plate when the second device is in an outwardly extending position with respect to the first device. The second device can move into a position overlying the first device to present a convex upper surface on the second device for supporting the fingers of the hand when the dorsal surfaces of the hand and wrist are to be exposed. The parts of the apparatus are made of metal to permit them to be steam autoclaved for sterility.
