摘要： An anterior cervical plate is disclosed, along with threaded fasteners for securing the plate to vertebrae or other osseous material. The cervical plate has several pockets or apertures, preferably at least four, to receive a corresponding number of the fasteners. The pockets have spherical surfaces, and the fasteners have heads with similarly sized spherical surfaces, which when engaged permit each of the fasteners to be oriented at a variety of projection angles with respect to the plate. In connection with each pocket, the cervical plate incorporates a fastener retaining feature. The feature can take the form of a cantilevered tab or a beam supported at its opposite ends, in each case plastically deformable between an open position for admitting the fastener and a closed position for preventing retraction.

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.
