Abstract
The Ilizarov method is used to correct bone deformities by using an adjustable frame
to simultaneously perform alignment and distraction of an open-wedge osteotomy. We
have adapted the idea of fixation-based surgery, which requires computer-assisted plan-
ning and guidance, to the Ilizarov method with the Taylor frame.
This work incorporates the kinematics of the Taylor frame (a Stewart platform)
into the planning and application phases of surgery. The method has been validated in
laboratory studies. The study shows that the method requires almost no intraoperative
X-ray exposure and that complex corrections can easily be achieved.
1 Introduction
In previous work [2] we introduced the idea of fixation-based surgery, using a fixed
