Abstract: A modular prosthesis is disclosed that includes a neck member having a tapered neck body. The modular prosthesis further includes a sleeve component having a first elongated tapered bore. The tapered neck body is received within the first elongated tapered bore so as to taper lock the sleeve component to the neck member. The modular prosthesis also includes a stem member configured to be implanted into a medullary canal of a bone. One of the neck member and the stem member includes a second elongated tapered bore. The other of the neck member and the stem member includes a tapered post that is received within the second tapered bore so as to taper lock the neck member to the stem member.

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.
