Patent ID: 7392076

Claim:
A system for registering two dimensional image data to intxa-operatively digitized landmarks obtained during a joint arthroplasty procedure on a patient having a joint in need of such a procedure comprising: a surgical navigation system capable of determining a position and an orientation of an object within a working volume, including a central processing unit, a display, a memory unit and a storage unit; means for importing the two dimensional image data for the joint into die memory unit; means for performing an intra-operative anatomical survey of the joint and an associated limb to digitize selected landmarks and determining a mechanical axis for the limb; means for registering the two dimensional image data to the mechanical axis and displaying a registered image of the mechanical axis and the two dimensional image data on the display; and means for assisting in guiding a cutting jig into position within the joint based on the landmarks while showing the registered two dimensional image data in relation to the landmarks, wherein the position and the orientation of the cutting jig can be tracked by the surgical navigation system.
