Abstract
The invention comprises a lateral ankle fusion plate, a jig for use with the fusion plate and a method for ankle fusion of the joints between the tibia, the talus, and the calcaneus. In addition, a separate fusion screw from posterior to anterior through the calcaneal tuberosity into the distal tibia is useful and can be placed using the targeting jig of the invention. The plate includes a C-shaped stirrup portion that wraps the bottom of the calcaneus and is provided with a screw hole for a T-T-C-fusion screw. A C-shaped targeting jig is provided that interfaces with the plate to allow for placement of the calcaneal screw and has an additional attachment for placement of the independent fusion screw so as to avoid impingement with the plate, and plate screws. The invention also relates to a method of surgery that incorporates the use of the plate, the jig and the tibial/talar/calcaneal fusion screw for an arthrodesis of the ankle joint.
