Abstract
Systems and methods for registering and tracking multiple anatomical structures, e.g., multiple vertebrae, as a single functional unit for surgical procedures are disclosed herein. In some embodiments, the system can include a bone bridge for attaching a navigation marker to multiple vertebrae and for limiting or preventing movement between the multiple vertebrae. Various ways of attaching the bone bridge are disclosed, including fasteners that extend through gaps or throughholes formed in the bridge, bridges having a jaw portion that clamps the underlying bone, and bridges formed of adhesive or cement and directly attached to the bone. Various adjustment features are also disclosed, including joints that allow the position and/or orientation of the bridge to be adjusted in one or more degrees of freedom, and bridges that include telescoping portions or other features for adjusting a length of the bridge.
