Abstract
A modular femoral prosthesis includes a stem member adapted to be implanted into a medullary canal of a femur. The stem member has a continuously tapered elongated bore and a threaded aperture defined therein. A first end of the elongated bore defines a post-receiving opening. The post-receiving opening is defined in a proximal end surface of the stem member. The elongated bore extends between the post-receiving opening and a threaded aperture. The femoral prosthesis also includes a neck member having a neck body, a head-receiving support member secured to the neck body so as to extend outwardly therefrom, and a tapered post secured to the neck body so as to extend outwardly therefrom. The tapered post is adapted to be received into the elongated bore of the stem member. A method of performing a joint replacement procedure by use of a modular prosthesis is also disclosed.
