Abstract:
1. A method of installing an ankle prosthesis system comprising: providing an artificial talar joint surface, providing a family of talar stem components having different physical characteristics, each talar stem component being sized and configured to be attached to the artificial talar joint surface, selecting an ankle region to be treated, the ankle region including a talus, a calcaneus, and a joint between the talus and the calcaneus, analyzing the morphology of the ankle region, selecting among the family one of the talar stem components having a desired physical characteristic based upon the analysis, forming a prosthesis-receiving cavity that traverses the joint between the talus and the calcaneus, installing the selected one of the talar stem components in the prosthesis-receiving cavity to prevent movement of the joint, and attaching the artificial talar joint surface to the selected one of the talar stem components.
