    摘要: A positioning block (10) for use in total knee replacement surgery, permitting five degrees-of-freedom movement relative to a bone element (39) to which it is fixed. The positioning block (10) comprises a rotational mounting element (14) that is removably engaged to the bone element such that the mounting element (14) is selectively rotatable relative to the bone element, about three substantially perpendicular axes of rotation. A guide body portion (12) is engaged with the mounting element (14) such that it is translatable relative thereto along a proximal-distal axis (43) and an anterior-posterior axis (47), while being rotationally fixed relative to the mounting element (14) such that the guide body portion (12) and the mounting element (14) rotate together relative to the bone element (39).

    摘要: A positioning block for use in knee surgery includes a rotational mounting removably engageable to the bone element by a multi-axial fastener such that the mounting element is selectively rotatable relative to the bone element about at least two substantially perpendicular axes of rotation. A guide body portion is engaged with the rotational mounting element such that it is translatable relative thereto along while being rotationally fixed relative to the mounting element. The guide body portion is moveable relative to the bone element in at least three degrees of freedom, the three degrees of freedom including at least two rotational degrees of freedom and at least one translational degree of freedom. A trackable member on the guide body portion is identified and tracked by a computer assisted surgery system.

    摘要: A tool for digitizing a mechanical axis of a tibia using a computer-assisted surgery system is described. The tool includes upper and lower mounting ends interconnected by an alignment rod extending therebetween. The upper mounting end is releasably fastenable to an upper reference point on a tibial plateau and the lower mounting end includes a self-centering malleoli engaging mechanism having opposed caliper arms displaceable in a common plane relative to each other for clamping engagement with the medial and lateral malleoli of the ankle. At least one trackable member is mounted to the alignment rod of the tool and is in communication with the computer assisted surgery system for providing at least orientation information of the alignment rod. The mechanical axis of the tibia is parallel to the alignment rod and extends between the upper and lower reference points when the tool is mounted on the tibia.

    摘要: A method of determining a reference point on condyles of a femur uses a computer assisted surgery system having a digitizer with perpendicular first and second planar surfaces, the digitizer being locatable and trackable in three dimensional space by the computer assisted surgery system. A digitized plane is created using the digitizer, the digitized plane being a posterior plane and/or a distal plane of the condyles. The posterior plane and the distal plane are respectively defined by the first and second planar surfaces of the digitizer. A location of the reference point in the digitized plane is then determined using the computer assisted surgical system. The reference point is a most remote point of the femur within the digitized plane.

    摘要: A computer assisted surgery system for conducting orthopedic surgery on a knee joint includes a condyle digitizer having a posterior condyle abutment surface defining a first plane and a distal condyle abutment surface defining a second plane perpendicular to the first plane, and a trackable member which is locatable and trackable in three dimensional space by the computer assisted surgery system to define at least orientation of the condyle digitizer in real time. A computer determines a most remote reference point of the femur of the knee joint lying within at least one of the first and second planes when the condyle digitizer is abutted against condyles of the femur such that the posterior condyle abutment surface abuts a posterior side of the condyles and the distal condyle abutment surface abuts a distal side of the condyles.
