Abstract:
1. A Tibiotalar Arthrodesis Guide (TAG) device used for fusion of the talus to the tibia comprising: a straight guide post upon which other components can slide; a curved arm having a pair of points which serve as indicators of pin exit sites; first and second pin guide cylinders parallel to one another and held by an arm which is perpendicular to the straight guide post, the arm, in turn, being fixed to a movable slide which translates along the straight guide post, allowing a surgeon to adjust the device for varying ankle sizes; a third pin guide cylinder oriented at an angle with respect to the first and second pin guide cylinders such that first and second pins inserted into each of the first and second pin guide cylinders and a third pin inserted into the third pin guide cylinder do not touch one another when inserted into the ankle, whereby the TAG device ensures that a screw successfully inserted with the aid of the third pin passes in between two parallel screws previously inserted with the aid of the first and second pins without touching the two parallel screws, enabling the orientation of three screws across the joint for superior stability without interfering with each other.
