  • Patent number: 4323059
    Abstract: An articulated splint for knee joint, of the type having two symmetrical portions each of which is made up of two uprights, an upper femoral one and a lower tibial one, are connected to one another by a rod. These uprights are to be fastened with their opposite number of the other portion, against one of the side faces of the corresponding part of a leg of a patient by a single cast covering the two portions of the splint and whose central part covering the knee is then cut out or eliminated. A first pin connects one of the uprights to the rod, this pin extending through the rod via an aperture whose longitudinal axis is oriented in the direction of a second connecting pin of the other upright on the rod. Pin-like members may be provided on the rod to limit the angular extent of possible movement of one or both of the uprights in one or both directions. The pin like members are threaded into respective threaded bores in the rod.
