Abstract:
A Tibiotalar Arthrodesis Guide (TAG) used for fusion of the talus to the tibia is comprised of several basic components. The main component is a straight guide post upon which other components can slide. A curved arm is featured at the end of the straight guide post, featuring points at the ends which serve as indicators of the pins' exit sites based upon the lines of action of the parallel pins. The parallel guide cylinders are positioned on a movable arm which translates superiorly and inferiorly on the guide post of the handle, allowing a surgeon to adjust the device for varying ankle sizes. A “home-run” pin guide cylinder for a home-run guide pin is oriented superiorly and at an angle to the parallel guide cylinders. Using a similar concept as the parallel guide cylinders, the “home-run” guide is also attached to a movable arm that can translate inferiorly and superiorly along the main guide post. A medial guide cylinder for a medial guide pin passes through one of a plurality of holes in a vertical guide arm. The surgeon has the flexibility to utilize either the “home-run” or medial pins, depending on the needs of the patient and preference of the surgeon and, in either case, the “home-run” and medial pin pass between the two parallel pins.
