Claim:
1. A tibial prosthesis removal system for removing a tibial prosthesis having an intramedullary stem comprised of a plurality of modular tibial stem component pieces having a longitudinal axis and surmounting a tibial tray component located in a tibial-talar space formed by a resected segment of a distal tibia portion and dome portion of a talus bone surmounting a calcaneus bone, said tibial prosthesis removal system comprising: a tibial tray alignment insert configured to occupy the tibial-talar space and comprising a superior face configured to operatively couple to the tibial tray component; an alignment guide member having a superior end and an inferior drill guide end, said alignment guide member configured to locate said inferior drill guide end at a location inferior to the calcaneus bone while having said superior end operatively coupled to said tibial tray alignment insert occupying the tibial-talar space for aligning a longitudinal axis of said inferior drill guide end with the longitudinal axis of the plurality of modular tibial stem pieces wherein a drill bit passed through said drill guide will be in alignment to bore a channel through the calcaneus and talus bones with a central channel axis coincident with the longitudinal axis of the plurality of modular tibial stem component pieces; and wherein said tibial tray alignment insert comprises a body having a pair of spaced apart attachment channels disposed through an anterior surface of said body and at least partially through said body.
