ABSTRACT:
An apparatus comprising an internal bone fixation apparatus for supporting and securing together two sections of a fractured elongated bone within a patient's body. Generally, the apparatus includes first and second fixation portions which are disposed in holes formed in the internal cavity of the fractured bone on respective sides of the fracture, and a means for connecting these fixation portions together. In the preferred version of the present invention, the connecting means is adjustable such that the first and second fixations portions can be drawn together or spread apart in the longitudinal direction, thereby similarly moving the first and second sections of the fractured bone. In addition, the structural and securing portions of the invention are made from strong resilient metals, that are not necessarily compatible for long term contact with the body of the patient. However, the metals are completely isolated from any contact with the body of the patient by insulating materials which are compatible.
