ABSTRACT:
A centralizer is installed on the end of the distal stem of a femoral prosthesis by virtue of splines cut into the sides of the tip of the distal end of the stem. Each spline has a relatively shallow distal portion and a deeper proximal portion. The centralizer has legs, each one of which has a radially inwardly directed surface designed to enter a respective spline. The proximal end of each leg of the centralizer is thicker in a radial direction including a radially inwardly directed projection entering the proximal portion of the spline to lock the centralizer in mounted position on the distal end of the stem. The centralizer acts to center the distal stem of the femoral prosthesis within the intramedullary canal of the proximal femur.
