摘要： According to the invention, there is provided a trial implant comprising a modular bracket defining a structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an external surface with a shape resembling the normal distal condyle of the femur. The bracket has an elongated central opening appointed to expose the resected bone of the femur, including a pair of tracks for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening. A replaceable insert covers the opening and articulates with a proximal aspect of the tibia during interoperative trial reduction of the knee joint, whereby prior removal of the bracket from the resected bone is unnecessary following shaping of the patellar groove. Preferably, the insert and guide tracks cooperate together to securely position the insert within the opening during trial reduction. A surgical method is also provided using the described trial implant guide.

摘要： Implant with multi-directional pivoting has a first component including a first articular surface and a fore-to-aft and side-to-side rotation device; and a second component including a second articular surface for mating with the first articular surface and a rotation device receptacle. The first component can be mated to the second component through cooperation of the rotation device and the rotation device receptacle, and the first component can cooperate with the second component in contact of the first and second articular surfaces and in articulation of the joint when the first component is mated to the second component. The implant can be an artificial joint which generally has natural load transfer capability. In a particular embodiment, the joint is a knee prosthesis; therein, the first and second components are femoral and tibial components, with the first articular surface a femoral condylar surface and the second articular surface a tibial condylar mating surface. In such a knee, the fore-to-aft component can be considered flexion, with the side-to-side component considered version. As well, a knee prosthesis can be provided with a device to support the patella on a smooth counter surface from full extension to flexion well past 100° and/or with a mechanism to prevent excessive downward travel of the tibial component.

摘要： An orthopedic component for total joint replacement that comprises a metal tray (3) and polymer liner (27), the metal tray having screw holes (7a, 7b) for fixation with screws (9) to bone and a circumferential rim or wall (15) with a smooth inner surface (21). The liner (27) is provided with a flexible sealing ridge (39) around its entire periphery, the sealing ridge being positioned so that it sealingly engages the tray rim so as to form a fluid-tight seal between the liner and the tray. The liner is provided with a locking mechanism comprised of tabs at the longitudinal ends of the liner which engage grooves in the front and rear of the tray. In this manner, the surgeon can readily install the liner within the tray after the tray has been surgically affixed to the resected skeletal structure by angling the liner and inserting a first tab into its respective groove and then by pressing the liner downwardly into the tray so that another tab at the opposite end of the liner engages its respective groove thus positively locking the liner with respect to the tray. Simultaneously with snap locking the liner within the tray, the flexible sealing ridge on the tray seals the liner with respect to the tray.

摘要： The present invention relates to a distal femoral surface shaping guide for mounting on an intramedullary alignment guide which references the central long axis of the femur in shaping the distal femoral surface and a method for shaping the distal femur using that shaping guide. The alignment guide of the present invention is adjustable relative to the surface of the anterior femoral cortex to insure that the anterior aspect of the distal femoral condyles is resected relative to that surface and, preferably, at the same level as that surface. The alignment guide of the present invention provides a main body which remains attached to the intramedullary alignment guide throughout the entire shaping of the distal femur. It thus requires fewer cutting guides and alignment steps than other shaping guides while allowing greater accuracy in shaping the distal femur relative to the central long axis of the femur.
