摘要： A tibial prosthesis includes a tibial tray and a post extending therefrom for receiving one or more modular stems of differing sizes. The stem provides a closed socket that registers with the post. A wedge lock fit tightens the stem to the post upon assembly. The stem has a cylindrical section and a tapering section. Fins extend longitudinally from the proximal end to the distal end of the stem, tracking both the cylindrical and tapering portion thereof so that each of the fins tracks a uniform diameter section of the stem for a majority of its length. The tapering section of the stem is equal to about one third of its over all length, and defines the distal end of the stem. The fins are longitudinally placed about the stem exterior surface, and are generally parallel. Between the fins are U-shaped channels that are similarly longitudinally extending and generally parallel. The stem provides a central longitudinal axis. The fins and channels are parallel to the central longitudinal axis of the stem.

摘要： A posterior stabilized femoral trial apparatus for preparing a patient's femur to receive a posterior stabilized femoral prosthesis includes a trial body with proximal and distal portions, the distal portion having an articulating surface for articulating with a patient's tibial component. A module fits the trial body at the proximal surface, the module being selected from a kit or group of modules of differing sizes and shapes. The module includes a rasping surface that extends longitudinally. The trial body includes cutting surfaces at the posterior condyles. The module is removably attachable to the trial body at the proximal surface. During use, the apparatus of the present invention enables the surgeon to resect the patient's femur in a revision surgical case using the trial itself and more particularly the rasping surface and cutting surface thereon.

摘要： A distal femoral cutting block apparatus for use in knee surgery includes an instrument body that has generally flat opposing parallel surfaces and a plurality flat peripheral surfaces to form a generally rectangular body. The body provides anterior and posterior surfaces and medial and lateral surfaces. The transverse slot carries a valgus module that is movably disposed in the slot. The valgus module includes a tubular sleeve member having a pair of opposed sides that abut the body at the slot. A portion of the tubular sleeve member is threaded and the threaded portion extends away from the body. An open ended bore extends through the tubular member. The open ended bore of the tubular sleeve member of the module accommodates an intramedullary rod that fits the patient s intramedullary canal. A lock nut engages the threaded section of the module for locking the module in a desired position on the cutting block body by engaging the threaded portion and the instrument body to rigidly affix them together.

摘要： An improved patella clamp apparatus includes a scissor-like instrument frame having a pair of handles at one end portion. A patella holder and drill collet have gripping surfaces for holding a patient's patella therebetween during preparation for implantation of a prosthesis. The collet has arcuate slots for accepting the vertical ridge of the patella. A reamer or cutting instrument cuts a circular recess into the posterior face of the patella. The collet is supported by the frame and positioned opposite the elevator. The collet accepts a depth stop for referencing the posterior aspect of the patella. The collet provides a bore that supports a reamer or drill for forming the circular recess in the patella posterior surface.

摘要： A modular tibial trial prosthesis for attachment to a patient's surgically cut proximal tibia includes a tibial tray having proximal and distal surfaces, the distal surface to be fitted against the patient's surgically prepared proximal tibia during knee joint replacement surgery. The proximal surface of the tray accepts any one of a plurality of plastic liner inserts that fits the tray at the proximal tray surface with an interlocking connection. The liner inserts each have a distal surface for attachment to the tray and a proximal articulating surface that is receptive of a distal femoral articulating surface. The proximal articulating surface has concavely-shaped portions. The concavely-shaped portions of the liner inserts provide different articular geometries for selection by the user. A plurality of spacers of different thicknesses can be positioned in between a selected one of the plastic liner inserts and the tibial tray. Each spacer has proximal and distal surfaces. The spacers have connecting portions on each of said proximal and distal surfaces for forming respective connections with a tibial tray and a selected plastic liner insert. The liner inserts each have connecting portion on the distal surface thereof for connecting to the proximal surface of the spacer and to the proximal surface of the tray. The liner inserts and spacers each have a periphery in the form of a sidewall that extends generally perpendicular to the proximal surface of the patient's transversely cut proximal tibia. The periphery of the insert and spacers are of corresponding shape.
