Abstract

A jig is detachably secured to the proximal end of an installed intramedullary nail having a transverse bolt hole near the distal end of the nail. The jig comprises an offsetting arm which so mounts an elongate template as to be movable in a geometric plane substantially parallel to the nail. A guide bore near the distal end of the template is on an axis perpendicular to the geometric plane. When the jig is chucked to the nail, the axis of the guide bore of the template is parallel to the axis of the bolt hole of the nail, and both the guide-bore axis and the bolt-hole axis are at identical distance from the offsetting arm. The distal end of the template is adapted to removably mount a metal-detector establishing a magnetic-field about a directional axis, such that the metal-detector can be selectively moved or positioned on one and then the other side of a central position in which the template is strictly parallel to the nail. Template positions noted for equal detector signals on opposite sides of the central position enable determination of the central position and therefore the location at which the template guide bore is in axial alignment with the bolt hole of the nail.
