Abstract
A method for determining a resection volume of a pathologic femur having a femoral head and a femoral neck is provided. The method may determine a first point of a desired contour based on a pathologic alpha angle of the pathologic femur, determine a second point of the desired contour based on a desired alpha angle of the pathologic femur, determine a third point of the desired contour on the femoral neck of the pathologic femur, and generate a resection volume of the pathologic femur based on the first, second and third points of the desired contour.
Claims20
A method for determining a resection volume of a pathologic femur having a femoral head and a femoral neck, comprising the steps of:
- determining a first point of a desired contour based on a pathologic alpha angle of the pathologic femur;
- determining a second point of the desired contour based on a desired alpha angle of the pathologic femur;
- determining a third point of the desired contour on the femoral neck of the pathologic femur;
- and
- generating, at a processor, a resection volume of the pathologic femur based on a three-dimensional reconstruction of the first, second and third points of the desired contour obtained from each of a plurality of cross-sections of the pathologic femur.
A method for determining a resection volume of a pathologic femur having a femoral head and a femoral neck, comprising the steps of:
- receiving medical images of the pathologic femur from a medical imaging device;
- determining landmarks of the pathologic femur based on the medical images;
- determining at least a first contour point and a second contour point of the pathologic femur, the first contour point corresponding to a pathologic alpha angle, the second contour point corresponding to a desired alpha angle;
- determining a morphing region on the pathologic femur;
- and
- generating, at a processor, a resection volume based on a three-dimensional reconstruction of the first contour point, the second contour point and the morphing region obtained from each of a plurality of cross-sections of the pathologic femur.
A system for resectioning a pathologic femur having a femoral head and a femoral neck, comprising:
- at least one medical imaging device configured to output medical images of the pathologic femur;
- and
- a computing device in communication with the medical imaging device, the computing device including a memory and a processor configured to receive the medical images from the medical imaging device, determine a first point of a desired contour based on a pathologic alpha angle of the pathologic femur, determine a second point of the desired contour based on a desired alpha angle of the pathologic femur, determine a desired morphing region of the pathologic femur, and generate a resection volume of the pathologic femur based on a three-dimensional reconstruction of the first point, the second point and the desired morphing region obtained from each of a plurality of cross-sections of the pathologic femur.
