Paragraph Number

51

Often this planning includes determining a desired orientation angle for the deployment of the pedicle screw. As used herein, "orientation" refers to a direction, angle, position, condition, state, or configuration of a first object, component, part, apparatus, system, or assembly relative to another object, component, part, apparatus, system, assembly, reference point, reference axis, or reference plane. "Orientation angle" refers to an angle indicating how an orientation of one apparatus, device, component, module, structure, assembly, or system relates to another apparatus, device, component, module, structure, assembly, or system. An orientation angle may be measured in degrees or radians. Those of skill in the art will appreciate that the orientation angle used during preoperative planning and during the surgery can be measured based on an accepted coordinate system of a medical imaging system calibrated or registered to the body of the patient. Often such calibration of the medical imaging system to the cardinal planes and cardinal axis of the patient includes the use of certain landmarks on the body parts of the image.
