TRIAL FEMORAL PROSTHESIS FOR USE IN KNEE JOINT REPLACEMENT SURGERY

摘要

A posterior stabilized femoral trial apparatus (10) for preparing a patient's femur to receive a posterior stabilized femoral prosthesis includes a trial body (11) with proximal and distal portions, the distal portion having an articulating surface (13) for articulating with apatient's tibial component. A module (50) fits the trial body (11) at the proximal surface, the module (50) being selected from a kit or group of modules of differing sizes and shapes. The module (50) includes a rasping surface (71) that extends longitudinally. The trial body (11) includes cutting surfaces at the posterior condyles. The module (50) is removably attachable to the trial body (11) 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.
