  • Publication number: 20160242919
    Abstract: The present invention provides a method and device for restoring individual patient joint kinematics using minimally invasive surgical procedures. The instrumentation of the invention sculpts the articular surface of a first bone that normally articulates in a predetermined manner with a second bone. The instrumentation includes a bone sculpting tool and a mount for attaching the tool to the second bone. The implant system is comprised of implants that provide intraoperative surgical options for articular constraint and facilitate proper alignment and orientation of the joint to restore kinematics as defined by the individual patient anatomy.

  • Patent number: 8425516
    Abstract: Methods and devices for sculpting bones, particularly in preparation for implanting prosthetic devices to replace articulating bone joint surfaces. Improved bone removal devices including burr mills driven by gears and loop drives are provided. Reciprocating cutters and belt cutters are also provided. Some devices have either integral or removable expandable portions to vary the force and bone resection depth. Devices can have irrigation ports and plenums to remove bone fragments. Some cutters are dual cutters, adapted to remove bone in two or more regions, such as the knee joint, simultaneously.

  • Patent number: 7604637
    Abstract: A method and apparatus for minimally invasive total joint replacement. The method involves sculpting the articular surface of a second bone that normally articulates with a first bone by attaching a bone sculpting tool directly or indirectly to the first bone with the tool in bone sculpting engagement with the articular surface of the second bone, and then sculpting the articular surface of the second bone with the joint reduced and moving one bone with respect to the other. An implant is placed to replace the articular surface of the second bone using an impaction device directly or indirectly attached to the first bone, wherein the force to place the implant is reacted by the second bone and the first bone.
