    摘要： A femur cutting jig mechanism (FCJM) is provided having a number N1 of spaced apart FCJM contact points that correspond to a number N1 of spaced apart femur contact points on at least one of a medial condyle, a lateral condyle, and a trochlear groove on the patient's knee. The FCJM contact points are positioned in contact with the knee contact points, and a cut bar mechanism is positioned in contact with the FCJM to provide a location and an angular orientation of a cut bar plane that is to be used to resection and remove a selected portion of the patient's, knee. The FCJM is removed from the patient's knee, and a selected portion of the patent's knee is resectioned and removed. The number N1 is at most 12 in some embodiments.

    摘要： Aspects of present disclosures involve systems, methods, and apparatus for a bone mounted robotic-assisted orthopedic surgery system for precise implant position, soft tissue balancing, and guidance of tools during a surgical procedure, particularly partial or total knee replacement procedure. The system features a bone-mounted robotic arm with an end-effector for precise positioning of a surgical tool, positioning of implants, and balancing of soft tissues. The reconfigurable robotic system requires minimal training by surgeons, is intuitive to use similar to conventional instrumented surgery, and has a small footprint. The system works with existing, conventional instruments, patient-specific instruments, sensor-assisted systems, and computer-assisted systems and does not require increased surgical time and safely provides the enhanced precision achievable by robotic-assisted systems and computer-assisted technologies.

    摘要： Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a series of images of a patient's anatomy to determine a cut plane for use during a hip replacement procedure. To determine a cut plane for use during the procedure, the computer program determines a best fit line through the center of the neck of the femur, as well as a best fit line through the femoral shaft. In one particular embodiment, a cut plane through the femur may then be determined as perpendicular to the center line through the neck of the femur. Further, the location of these features in the images may be determined by analyzing the gray scale value of one or more pixels around a selected point on the image. The pixel with the lowest gray scale value may then be assumed to be the edge of the cortical bone in the 2D image.
