Abstract:
1. An adjustable tibial reaming guide positioning system for allowing a position for reaming of a distal tibia to be adjusted during total ankle arthroplasty for prostheses with an intramedullary stem, said system comprising: a tibial reaming guide having a reamer body sized to fit in a space formed by a resected segment of a distal portion of a tibia and a resected segment of a dome of a talus, said reamer body having an opened ended channel for removeably receiving a cannulated tibial reaming bit, said opened ended channel having a central longitudinal axis; and means, operatively coupled to said tibial reaming guide, for incrementally adjusting a position of said tibial reaming guide in the space formed by the resected segment of the distal portion of the tibia and the resected segment of the dome of the talus for locating said central longitudinal axis of said opened ended channel of said tibial reaming guide relative to a central longitudinal axis of the distal portion of the tibia during total ankle arthroplasty for prostheses with an intramedullary stem.
