Modular stem and sleeve prosthesis

An orthopaedic prosthesis system for replacement of an articulating portion of a long bone comprising:

• a plurality of sleeves having different sizes, each sleeve having an outer bone engagement surface and defining an axial bore though the sleeve, the bore including opposed proximal and distal female taper regions;
• a plurality of stems having different sizes, each stem having a distal end for fixation within a long bone and a proximal end including a male taper region engaged with the distal female taper of the sleeve;
• and
• a plurality of necks having different sizes, each neck having an articulating portion connecting element and a distal taper post, each neck defining an axial bore through the neck and extending through the distal taper post, the distal taper post being engaged with the proximal taper of the sleeve;
• wherein an implantable prosthesis is prepared by assembling a sleeve selected from the plurality of sleeves having different sizes, a neck selected from the plurality of necks having different sizes, and a stem selected from the plurality of stems having different sizes;
• the system further comprising a connecting element for the implantable prosthesis engaged with the proximal end of the stem, extending through the axial bore in the sleeve, extending into the axial bore in the neck and engaging the neck, the connecting element being from the neck.
