Abstract: A guide device for the placement of a bone screws or pin in the orthopedic treatment of bone fractures is disclosed. The guide device is constructed of a body having one or more tunnels for guiding therethrough an orthopedic pin for placement in the orthopedic treatment of a bone fracture. The body includes at least one frangible portion for separating the body from about the pin such that the body is removable while the pin remains in secured place within the bone.

Abstract: A surgical appliance for the fixation of fractured bones includes two anchoring members each adapted to be imbedded into a respective segment of a fractured bone. Each anchoring member has a head portion which extends from the bone, the head portion including a channel therethrough to receive a bolt. In one embodiment, one of the channels is threaded. The bolt, which is formed of a shaft and a head, has at least a portion of the shaft provided with screw threads which mate with the threads of the one channel. The shaft of the bolt is adapted to pass through the channel of the first anchoring member and to be threadedly received in the channel of the second anchoring member so as to exert a compressional force on the segment of the fractured bone when the bolt is tightened. In another embodiment, the channels of both heads of the anchoring members are provided with screw threads.

Abstract: A prosthetic nail for stabilizing fractures in the supracondylar area of the femur has an elongated flat shape and tapers substantially over its entire length from a relatively thick head (about 0.4 .times. 0.5 inch) to a relatively thin tip (about 0.2 .times. 0.05 inch). The elevational configuration of the nail has a thin elongated midportion (about 0.1 inch thick) with two curved ends. The larger head end is about 0.5 inch thick formed by inside and outside radii about 2 and 3 inches long. The curved head end extends longitudinally about 2.5 inches from the midportion. The thinner tip end has a radius of about 1.75 inches extending longitudinally about 1 inch. The plan configuration of the nail is about 11 inches long tapering from a 0.4 inch wide head to about a 0.2 inch blunt rounded tip. A hole for a lag screw is provided through the head end either at right angles to the elevational length of the nail or at a slight inward inclination thereto.
