ABSTRACT:
A multi-piece trial femoral component kit for use in sizing a femoral cavity prior to implantation of a prosthetic femoral implant. The trial femoral component kit has at least two distal trial components of different size and two proximal trial components of different size and mating elements which allow the proximal and distal components to be releasably coupled to form a femoral trial prosthesis. The distal trial component combines with the proximal trial component to form the stem of the femoral trial prosthesis, the joint of the two components located in the circumferential area between the gluteal tuberosity and about 2" below the pectineal line of the femur when the femoral trial is inserted within the femur. The distal and proximal components may further include means for selectively combining the proximal and distal components to form a femoral trial prosthesis that corresponds to an available prosthetic femoral implant. The dimensions of the distal and proximal components may be undersized when compared to the corresponding regions of the prosthetic femoral implant.
