Abstract:
1. A universal targeting apparatus for targeting a transverse aperture in an intramedullary implant, being one of a rod and a bone nail, for introducing a lag screw into the aperture, in which the transverse aperture has an aperture axis that is oriented at one of at least two angles relative to a longitudinal axis of the intramedullary implant, comprising: a generally U-shaped body having one end configured to be coupled to a proximal end of the intramedullary implant and a mounting portion at an opposite end of the body, the mounting portion defining a slot extending parallel to a plane containing the aperture axis and the longitudinal axis when the body is coupled to the intramedullary implant; and an arm member defining an arm longitudinal axis, the arm member rotatably mounted to the mounting portion of the U-shaped body and having a first portion and a second portion offset from the first portion, the first portion defining a first portion longitudinal axis and at least one first bore with a longitudinal first axis, and the second portion defining a second portion longitudinal axis and at least one second bore with a longitudinal second axis, the arm member configured so that the longitudinal first axis is aligned with a first aperture axis oriented at one of the at least two angles when the arm member is rotated relative to the mounting portion to a first position in which the longitudinal first axis resides within the plane, and so that the longitudinal second axis is aligned with a second aperture axis oriented at a different one of the at least two angles when the arm member is rotated to a second position, different than the first position, in which the longitudinal second axis resides within the plane, each of the first portion and the second portion of the arm member includes an indicia indicative of a corresponding one of the aperture axis angles; wherein the mounting portion includes two arms spaced apart to define the slot, and the arm member is mounted to the mounting portion so as to be positioned in the slot between the two arms and to rotate about a pivot axis perpendicular to the plane.
