<p>The present invention provides a method and apparatus for achieving the fixation of a bone having medullary canal, and permits the secure and highly repeatable location of the distal locking screws used in intramedullary nailing of long bone fractures. The distal end of an intramedullary nail (31) is locked to the distal portion of a bone by inserting a guide wire (11) into the medullary canal of the bone, drilling a pilot hole through the near cortex of the bone, and using a suitable locator tool (21) that has an arrangement for grabbing the guide wire. The intramedullary nail is then inserted until it engages with the locator. A distal alignment fixture (41) engaged with the locator can then be used to determine the location of the first distal locking hole. After insertion of the first distal locking screw, the second distal locking screw can be located.</p> |
