CAS SYSTEM FOR CONDYLE MEASUREMENT

摘要

A method of determining a reference point (23,25) on the condyles (13,15) of a femur (11) uses a computer assisted surgery system (10) having a digitizer (20) with perpendicular first and second planar surfaces (30, 32), the digitizer being locatable and trackable in three dimensional space by the computer assisted surgery system (10). A digitized plane (27,29) is created using the digitizer (20), the digitized plane being either a posterior plane (29) and/or a distal plane (27) of the condyles (13,15). The posterior plane (29) and the distal plane (27) are respectively defined by the first and second planar surfaces (30, 32) of the digitizer (20). A location of the reference point (23,25) in the digitized plane is then determined using the computer assisted surgical system (10). The reference point (23,25) is a most remote point of the femur within the digitized plane.
