Abstract

A targeting system and method is disclosed for the distal locking of intramedullary nails. The targeting system comprises a first fixation system, a second fixation system, and an aiming guide. After implantation within the intramedullary canal of a bone, the distal screw holes of an intramedullary nail are first aligned using conventional radioscopy equipment. The targeting system is then introduced between the radioscopy equipment and the patient such that the aiming guide of the targeting system is roughly aligned with the distal screw holes. The first fixation system is adapted to be fixedly coupled to an operating surface upon which an intramedullary nail fixation procedure may be performed. The second fixation system is adpated to be fixedly coupled to the handle of the implanted intramedullary nail. Rough adjustments to the first and second fixation systems enable an initial positioning of a drill with a first distal screw hole. The aiming guide, which is disposed between and fixedly coupled to the first fixation system and the second fixation system, is used to perfect alignment of the drill with the first distal screw hole. Once a precise alignment with the first distal screw hole has been realized, a mechanical adjustment to the aiming guide may allow for a rapid alignment of the drill with the second distal screw hole of the implanted intramedullary nail.
