TOTAL ANKLE REPLACEMENT WITH ANATOMICALLY FITTED TALAR COMPONENT

摘要

An anatomically fitted talar component for use in an ankle replacement system having a body including a talar surface having a portion contoured to approximately or exactly fit with a surface portion of a three dimensional rendering of bone of a talar dome; and a tibial surface configured for forming a joint with a second component of the ankle replacement system. A method of forming the talar component by: (i) obtaining image data of the talar dome, (ii) using the data to create a three-dimensional model of the talar dome, and (iii) forming a body having a talar surface that approximately or exactly fits with a portion of the surface of the three-dimensional model.
