The invention provides methods and apparatus for accurately cutting bones with a surgical cutting device, such as a sagittal saw, using a surgical navigation system without use of a complex cutting jig. A surgical navigation system is used to navigate a guide tube to be used to drill a k-wire into the bone. The k-wire will act as a guide to control at least one degree of freedom of a saw blade for making a cut in the bone. In an exemplary high tibial osteotomy procedure, in which two intersecting planar cuts must be made in the tibia in order to remove a wedge of bone, a surgical navigation marker is mounted on the guide tube. The surgeon uses the surgical navigation system to navigate the guide tube to the desired varus-valgus angle and height of the first cut and then drills a k-wire into the tibia at that varus-valgus angle using the guide tube. The process is repeated for the second cut. The surgeon then uses the two k-wires as guides for controlling the varus-valgus angle of a sagittal saw for the two planar cuts. The surgeon rests the saw blade flat on the respective k-wire to define the varus-valgus angle of the cut. The saw itself also is navigated, with the surgical navigation system providing a display showing the surgeon at least (1) the varus-valgus angle, (2) the cut depth, and (3) the anterior-posterior slope. The anterior-posterior slope and the depth of the cut is controlled freehand by the surgeon.

Systems and processes for use in computer aided or computer navigated surgery include probes with indicia which define axes relative to which images are desired. Computer functionality generates and stores the position and location of these indicia. After the indicia have been registered into the system, imaging apparatus may be moved, manually or automatically, into the correct position to capture the desired image. In various embodiments, probes may be left in place during, or removed prior, to imaging. In addition, several axes may be defined, and their location and position data generated and stored, so that the imaging device may move into each position in turn to capture a series of desired images.
