Modular trial hip replacement system

Abstract

Abstract A multi-piece trial femoral component kit is used for preparing and sizing a femoral cavity prior to implantation of a prosthetic femoral component. The trial component kit has at least three trial stem portions (12) of differing size and at least three trial body portions (14) of different size. The stem and body portions include mating male (28) and female (30) elements which allow the stem portions to be securely coupled to the body portions. In order to ensure that the so-coupled stem and body portions from a trial femoral component having a size equal to an available orthopedic femoral implant, the male and female elements include a key (32) and keyway (34) which are sized so that only trial stem and body portions resulting in an available femoral implant can be combined and used as a trial femoral component.
