Abstract: A system and method for providing computer assistance for performing a medical procedure provides a graphical user interface to guide and/or assist a user, for example a surgeon, performing the medical procedure, whether surgical or non-surgical. The computer-assisted system comprises a software application that may be used for a medical procedure.

Abstract: A method of clavicle fracture fixation includes using a K-wire to create a pilot hole extending longitudinally through the medullary canal of the lateral and medial fragments of the fractured clavicle while the fragments are reduced, enlarging a medial portion of the pilot hole in the lateral fragment and a lateral portion of the pilot hole in the medial fragment, wherein such enlarged portions are together sized for receiving the clavicle nail, attaching the lateral end of the clavicle nail to the K-wire, manipulating the K-wire such that substantially the entire length of the clavicle nail is positioned inside of the lateral fragment, aligning the lateral and medial fragments longitudinally, and manipulating the K-wire such that approximately half of the length of the clavicle nail is positioned within the medial fragment and approximately half of the nail is positioned within the lateral fragment.

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: A specially-programmed, computer-assisted surgery system is used to reduce the number of fluoroscopic images required to be taken during the course of a intramedullary nail procedure, eliminates the need for a Steinman pin, and assists the surgeon in properly aligning and securing the nail during insertion.

Abstract: A method and apparatus for performing a calibration and navigation of a member. The member may be calibrated relative to a selected portion, such as a sensor on an instrument. The calibrated member may then be navigated with a selected system. The calibration technique can be infinitely flexible and not rigid or designed for specific components. Moreover, the calibration may occur when the member is interconnected to an end of the instrument that is non-co-axial with another end of the instrument.

Abstract: A system and method for providing computer assistance for performing a medical procedure provides a graphical user interface to guide and/or assist a user, for example a surgeon, performing the medical procedure, whether surgical or non-surgical. The computer-assisted system comprises a software application that may be used for a medical procedure.

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: A system and method for providing computer assistance for performing a medical procedure, for example spinal fixation, provides a graphical user interface to guide and/or assist a user, for example a surgeon, performing the medical procedure, whether surgical or non-surgical. The computer-assisted system comprises a software application, for example a spinal fixation application, that may be used for a medical procedure, for example spine linking, etc.

Abstract: A computer-assisted knee replacement apparatus and method comprises a total knee replacement application for assisting, guiding, and planning a total 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: A computer-assisted external fixation apparatus and method comprises an external fixation application for assisting, guiding, and planning an external fixation procedure. The external fixation application cooperates with a tracking system to acquire kinematic data corresponding to a selected joint during manipulation of the selected joint and/or acquire image data of patient anatomy and determine a kinematic parameter for the selected joint using the kinematic and/or image data, such as an axis of rotation or plane of movement. The external fixation application may then be used with the tracking system to provide real-time alignment information for alignment of an external fixator based on the information associated with the determined kinematic parameter.
