The intramedullary fixation device for use in fixing the relative position between a tubular bone and an adjoining bone has, according to the present invention, an intramedullary nail intramedullary nail that is inserted into the medullary canal of the tubular bone whose position is to be fixed, an elongated blade for insertion into the adjoining bone whose position is to be fixed relative to that of the tubular bone, a washer for use when the nail's design is such that its end section is not perpendicular to its longitudinal axis, and a screw that passes through openings in the blade and washer and into a threaded bore in the nail so as to, when tightened, lock the screw, washer, blade and nail together so as to prevent relative movement between these elements. The related method of the present invention comprises the steps of providing the listed elements for the fixation device and then seating the intramedullary nail and blade in the respective tubular and adjoining bones, and inserting the fixation means through a blade passageway and into a nail threaded bore so as to lock the elements together and to prevent relative movement between the treated bones. |
