    摘要： A computer assisted method creates accurate CAD/CAM models of custom orthopedic implants is provided. Information about bone geometry is acquired through medical imaging such as CT image scans. The desired bone surface region is extracted as a polygonal mesh after processing the 3D images. A smooth and accurate B-Spline surface is fitted to the polygonal mesh that is thickened to a solid CAD model. A patient-specific customized implant is manufactured from the obtained CAD model. The patient-specific customized implant is implanted in a patient by a surgeon in an operating room. A processor based system to generate a CAD/CAM file of the patient-specific customized implant and a manufacturing system enabled to manufacture the implant from the CAD/CAM file are also disclosed.

    摘要： A method on a processor customizes a fixation plate for repairing a bone fracture. A digital CAD model of an implant contains smooth analytic geometry representations including NURBS. The CAD geometry is directly manipulated to generate a customized implant CAD model that conforms to the desired region of the bone surface of a patient. Direct manipulation of NURBS geometry is computationally fast and suitable for interactive planning. The patient specific customized implant is produced directly from the generated customized CAD model with a standard CNC machine before surgery. The patient customized implant is implanted in the patient.
