摘要： A computer-implemented method of preoperatively planning a surgical procedure on a knee of a patient including determining femoral condyle vectors and tibial plateau vectors based on image data of the knee, the femoral condyle vectors and the tibial plateau vectors corresponding to motion vectors of the femoral condyles and the tibial plateau as they move relative to each other. The method may also include modifying a bone model representative of at least one of the femur and the tibia into a modified bone model based on the femoral condyle vectors and the tibial plateau vectors. And the method may further include determining coordinate locations for a resection of the modified bone model.

摘要： A smooth mating surface model defining a mating surface of a customized arthroplasty jig is generated. For example, sagittal slices of a volumetric image of a patient bone are segmented with segmentation splines. An anatomically accurate model of the patient bone is generated from the segmentation splines. The anatomically accurate model includes anatomically accurate segmentation splines. The anatomically accurate segmentation splines are transformed into mating surface contours. Any inadequate segments of the mating surface contours are modified to obtain modified mating surface contours. A mating surface model of the patient bone is generated based on the mating surface contours and the modified mating surface contours. Three-dimensional cross-sections of the mating surface model are smoothed to generate the smooth mating surface model.

摘要： Methods of manufacturing a custom arthroplasty resection guide or jig are disclosed herein. For example, one method may include: generating MRI knee coil two dimensional images, wherein the knee coil images include a knee region of a patient; generating MRI body coil two dimensional images, wherein the body coil images include a hip region of the patient, the knee region of the patient and an ankle region of the patient; in the knee coil images, identifying first locations of knee landmarks; in the body coil images, identifying second locations of the knee landmarks; run a transformation with the first and second locations, causing the knee coil images and body coil images to generally correspond with each other with respect to location and orientation.

摘要： A method for planning an arthroplasty procedure on a patient bone. The method may include accessing generic bone data stored in a memory of a computer, using the computer to generate modified bone data by modifying the generic bone data according to medical imaging data of the patient bone, using the computer to derive a location of non-bone tissue data relative to the modified bone data, and superimposing implant data and the modified bone data in defining a resection of an arthroplasty target region of the patient bone.
