摘要： A method of resecting distal and anterior portions of a distal portion of a femur for a bicompartmental prosthesis is provided. The method includes generating a geometric representation of the distal portion of the femur. A virtual anterior resection plane is calculated at a predetermined depth and is oriented at a predetermined angle relative to the femur. The method identifies a distal-most point of a lateral portion of the virtual anterior resection plane and an AP line. A varus/valgus angle and an anterior-posterior distance are calculated. Anterior and distal resection guides are navigated according to the parameters calculated from the method.

摘要： Artificial implants having reduced area to provide reduced wear are provided. The reduced area is particularly located at areas where greatest wear is exhibited. In a particular embodiment of a mobile bearing knee implant, the area is reduced on the mobile bearing insert underside, where it contacts a tibial component. The reduced area may be any shape of indentations, for example, grooves, dimples, straight patterns, curved patterns, crossing patterns, holes, channels or slots. The indentations may be various sizes, and have been found to be particularly effective if covering about 10% to about 20% of the insert at depths between about 1-2 mm.

摘要： A method for performing shoulder arthroplasty or hemiarthroplasty is provided. The method includes generating navigational reference information relating to position and orientation of a body part forming at least a portion of the shoulder joint. The reference information may be stored in a computer. Navigational references are attached to the body part and an object. Information is received regarding the position and orientation of the object with respect to the body part and the object is navigated according to this information. The body part may be modified using the object and the modification may be displayed on a monitor associated with the computer. The navigational references may be used to track a shoulder arthroplasty trial component. Information is received regarding the position and orientation of the trial component with respect to the body part. This information is used to navigate the trial component to the body part.

摘要： A mobile bearing knee prosthesis enables a surgeon to convert a mobile bearing insert having articular surfaces, supported by a tibial base plate or tray from a rotating and translating prosthesis to one that rotates only. This conversion is accomplished with a fastener or locking member that connects through an opening in the insert to the tibial base plate. This prosthesis can be used as part of a total knee surgery when the surgeon chooses to use a prosthesis that incorporates a movable articular surface. In one embodiment, a projecting portion extends proximally from the insert and cooperates with a cam on the femoral component. The projecting portion can be a post extending up from the proximal surface of the insert and the femoral component includes an intercondylar surface that may contact the post to constrain the relative motion between the femoral component and the insert. In another embodiment, the insert is a two part assembly that includes a larger member with a central opening and a smaller member that fits the opening.

摘要： A stem extension for surgical implants such as tibial or femoral knee implants. The stem extension is interposed between the stem and its load bearing component (i.e., tibial tray or condylar component) and angularly orients the attached stem relative to the load bearing component to facilitate positioning of the stem in the bone canal and alignment of the load bearing component with the mechanical axis of the leg. The extension includes a female taper that engages the load bearing component. The extension also includes a male taper having a longitudinal axis oriented at an angle relative to the longitudinal axis of the female taper. Engagement of the male taper with the stem thereby orients the stem at an angle relative to the longitudinal axis of the load bearing component. Because the bone canal into which the stem is inserted is oftentimes angled relative to the mechanical axis of the leg, such orientation of the stem adjusts for the contour and/or angulation of the canal and facilitates positioning of the stem in the canal in a manner that promotes the desired alignment between the load bearing component and the mechanical axis of the leg, thereby allowing the implant to more closely replicate the geometry of the knee and leg. In addition to being oriented angularly, the female and male taper of the extension may also be offset parallel to facilitate insertion of the stem into canals that are not only angled relative to, but also offset from, the mechanical axis of the leg.
摘要翻译：手术植入物如胫骨或股骨膝关节植入物的延伸部分。杆延伸部插入在杆和其承载部件（即，胫骨托盘或髁部件）之间，并且相对于承载部件成角度地定向附接的杆，以便于将杆定位在骨槽中并且承载轴承具有机械轴的部件。该延伸部包括与承载部件接合的阴锥形。延伸部还包括具有相对于阴锥度的纵向轴线成一定角度定向的纵向轴线的阳锥形。阳锥与杆的接合使得杆相对于承载部件的纵向轴线成角度。因为杆插入其中的骨管通常相对于腿的机械轴线成一定角度，所以杆的这种取向对于管道的轮廓和/或角度进行调节，并且有助于以一种方式将杆定位在管道中这促进了承载部件和腿的机械轴线之间的期望的对准，从而允许植入物更紧密地复制膝部和腿部的几何形状。除了被成角度地定向之外，延伸部的阴和阳锥形也可以平行地偏移，以便于将杆插入到运河中，其不仅相对于腿的机械轴线成角度，而且偏离腿的机械轴线。
