External fixators for elective rearfoot and ankle arthrodesis. Techniques and indications.

Since its introduction to the western hemisphere in the mid 1980's, Gavriel Ilizarov's ring fixator system has been studied extensively and shown to be a superior mechanical construct for stabilizing limb segments. This newfound form of external fixation has radically changed many elements of foot and ankle reconstruction, providing a modular device that can accommodate the complex limb deformities while performing multiple tasks. This article summarizes the authors' experience with compression arthrodesis of the rearfoot and ankle using external fixation.
