SYSTEM AND METHOD TO CHECK CUT PLANE ACCURACY AFTER BONE REMOVAL

A device for checking post cut plane accuracy and alignment following bone removal in a bone of a patient during a computer-assisted surgical procedure to create a bone surface is provided. The device includes a body having an axis and adapted to contact the bone surface. One or more alignment features are associated with the body and are accessible when the body is in contact with the bone surface. Each of the one or more alignment features has a known orientation and position relative to the axis. A method for checking post cut plane accuracy and alignment following removal of bone from a patient to create a bone surface during a computer-assisted surgical procedure is also provided. A computer-assisted surgical system is provided that includes a tracking system, a tracked digitizer probe, the aforementioned device, a tracked surgical device, and one or more computers with software for determining the orientation.
