Abstract
An orthopaedic aiming device system is provided that includes a targeting device. The targeting device has a curved portion with an end and at least one guide opening formed therethrough. The curved portion also defines an arced axis. Connected to the end of the curved portion is a mounting portion that has at least one mounting opening formed therethrough. The mounting opening defines a mounting axis that is approximately orthogonal to at least one point on the arced axis of the curved portion. The orthopaedic aiming device system can also include mounting pins, a positioning device, and an orthopaedic implant. The mounting pins can include distancing features that interact with distance locking features of the mounting opening(s) to properly distance the targeting device from the orthopaedic implant. Also included is a method to target implant openings that have compound angled screw trajectories using an orthopaedic aiming device system.
