Abstract
An orthopaedic prosthesis for implantation in a patient's intramedullary canal includes a prosthesis body and a removable prosthesis stem portion that is connectable to the prosthesis body at the lower end portion of the prosthesis body. The stem is formed of an elongated stem member that is preferably conically shaped, having an inner elongated conical core with proximal and distal end portions. A helical portion extends around the core beginning at a position adjacent to the proximal end and terminating at a position adjacent to the distal end. The stem and body can be connectable using a wedge lock or taper-like connection. The prosthesis stem can provide a socket with internal threads for attaching a removal tool thereto.
