ABSTRACT:
A bone cutting guide block has a cutting tool guide surface and a navigation mount for a navigation tracker component for computer aided positioning of the guide for a resection procedure. In various embodiments, the guide includes a rotation means. Preferably, a swivel with a pivot apparatus is provided to limit rotation to permit controlled flexion-extension angle about the pivot with respect to the cutting guide surface. A fixing member through the swivel permits for varus-valgus adjustment of the guide surface. Optionally, a positioning actuator and/or biased resistance actuator implements more regulated flexion-extension angle adjustment with the swivel. Various traversing mechanisms, such as a threaded wheel or pivoted cam tool permit controlled proximal-distal adjustment of the cutting guide surface.
