Patent ID: 8303600

Claim:
A universal targeting apparatus for targeting a transverse aperture in an intramedullary implant, being one of a rod or 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 the proximal end of the intramedullary implant and a mounting portion at an opposite end of said body, said mounting portion defining a mounting portion longitudinal axis and a plane with the intramedullary implant when the body is coupled thereto, said plane containing the aperture axis; and an arm rotatably mounted to said mounting portion of said U-shaped body and having a first portion and a second portion offset from said first portion, said first portion defining a first portion longitudinal axis and at least one first bore with a longitudinal first axis, and said second portion defining a second portion longitudinal axis and at least one second bore with a longitudinal second axis, said arm configured so that said longitudinal first axis is aligned with an aperture axis oriented at one of the at least two angles when said arm is rotated relative to said mounting portion to a first position in which said longitudinal first axis resides within said plane, and so that said longitudinal second axis is aligned with an aperture axis oriented at a different one of the at least two angles when said arm is rotated to a second position, different than said first position, in which said longitudinal second axis resides within said plane, wherein one of said first portion and said second portion longitudinal axes is substantially aligned with said mounting portion longitudinal axis when said arm is in one of said first position and said second position and said first portion and second portion longitudinal axes are misaligned with said mounting portion longitudinal axis when said arm is not in either of said first position or said second position, wherein said arm is mounted to said mounting portion to rotate about an axis in said plane.
