Abstract

Abstract An autoclavable device for mechanically holding a limb, particularly the leg, in the optimum position for performing surgery thereon. The device includes a central support member having an outwardly projecting rod for detachably securing the support member to an operating table. The device also includes an upwardly extending arm that is pivotally connected to the central support member and is adapted to engage the leg on one side or the other of the knee. An extension member in the form of an elongated rod is connected to the central support by means of a ball joint to permit angular adjustment of the rod with respect to the support. Adjustably mounted on the extension member rod is a U-shaped member adapted to engage the lower extremity of the leg in the area of the ankle. A handle is provided at the outer end of the extension member rod to facilitate adjusting the angular position of the rod and thus of the lower extremity of the leg.
