Abstract: A harness for attachment about a knee femur and comprised of a rigid and non-flexible frame support two resiliently mounted clamping means and sensors is described for the non-invasive measurement of knee motion and its analysis in 3-D is described. The clamping means elements are urged under pressure outwardly for application against a skin outer surface at predetermined medial and lateral sites relative to a femur. A non-resilient adjustable stabilizing element is connected to the rigid frame and disposed at a predetermined location with respect to the medial clamping element in spaced relationship therewith and adjustable for clamping contact on a skin outer surface and in alignment with the center of a medial condyle of the femur whereby to stabilize the rigid frame about a knee. An attachment rod is secured to the harness and has straps for securing the rod above the knee.

Abstract: A computer-assisted knee replacement apparatus and method comprises a knee replacement application for assisting, guiding, and planning a unicondylar knee replacement procedure. The apparatus and method cooperates with a tracking system to determine implant sizing and location. The apparatus and method also cooperates with the tracking system to determine required tibial and femoral preparation corresponding to the implant size and location and provides real-time monitoring of the tibial and femoral surface preparation procedures.

Abstract: Hip replacement surgery involves replacing the head and neck of the femur with an artificial component having a ball-shaped head and neck similar to that of a replaced femoral head and neck and inserting a cup-shaped component into the acetabulum to act as a liner to receive the ball of the femoral component. During this procedure, a surgeon encounters or has to overcome several problems. These problems include establishing the correct inclination, version and medialization for the acetabular component of the artificial hip; the correct version or angle of the femoral component; and maintaining correct leg length.

Abstract: As a general overview, the system 10 is used to assist the surgeon in performing an operation by acquiring and displaying an image of the patent. Subsequent movement of the patient and instruments is tracked and displayed on the image. Images of a selection of implants are stored by the system and may be called to be superimposed on the image. The surgical procedures may be planned using the images of the patient and instruments and implants and stored as a series of sequential tasks referred to defined datums, such as inclination or position. Gestures of the surgeon may be used in the planning stage to call the image of the instruments and in the procedure to increment the planned tasks.

Abstract: A system for planning a surgical operation by using virtual representation of bones and/or a bone joint is disclosed. The system includes at least two reference frames each of which having first and second ends. The first end of each reference frame is configured to be affixed to the bones. The system also includes a plurality of first electromagnetic or acoustic wave emitting devices attached to the second end of each of the reference frames. In addition, the system includes a moveable pointer having first and second ends, wherein the first end is a pointing tip configured to be positioned at a plurality of desired locations of the bones or the bone joint and a plurality of second electromagnetic or acoustic wave emitting devices attached to the second end of the moveable pointer. Furthermore, the system includes a three-dimensional localizer device.

Abstract: A method and apparatus are disclosed for defining a three-dimensional coordinate system in relation to an anatomical structure (64) for use with computer-assisted surgical systems. At least three landmarks (66, 68, 70) associated with the anatomical structure (64) are identified. Landmarks are identified using a digitization device (96) and their location refined using at least one single calibrated X-ray image. Using the landmarks (66, 68, 70), first and second planes are defined, the second plane being orthogonal to the first plane. These planes define a coordinate system, which can be used to ascertain the position trajectory of any object (80) with respect to the anatomical structure. Exposure to imaging radiation and additional surgical procedure is minimized.
