A modular orthopedic prosthesis has a body with a generally triangular cross-section near one end, allowing its angular corners to bite or incise into the surrounding bone cavity for rotational stability. A stem, which may be either unitary or modular in structure, is received within a through-bore of the body, having a proximal neck and distal shaft. A connecting sleeve receives the stem and is, in turn, received within the bore of the body, then actuated to lock the stem and body together. |
