Abstract:
A surgical implant kit designed for ankle arthrodesis, comprising:a. at least one tibio-calcaneal rod having a tip, a shaft, and a base, said rod being properly sized and suited for surgical insertion through a calcaneal bone so that the tip enters a tibial bone to establish tibio-calcaneal arthrodesis, and having an oblique hole passing through the shaft to accommodate a screw; and, b. at least one screw having a base, a shaft, and a threaded tip region, said threaded tip region being small enough to pass through the oblique hole in the shaft of the tibio-calcaneal rod, and said screw being properly sized and suited for surgical insertion at an angle through a calcaneal bone in a manner which causes at least a portion of the threaded tip region to enter a lower end of a tibial bone, wherein the oblique hole passes through the shaft of the rod at an angle with respect to the shaft, and wherein the rod and screw are designed to fit together inside an ankle joint, thereby establishing an ankle arthrodesis assembly, and wherein the threaded tip region of the screw allows the screw to establish compression of the tibial bone against the calcaneal bone when the screw is rotated during a surgical emplacement procedure.
