Abstract
The invention provides a modular three-component assembly for replacing a portion of a patient's femur or humerus. A neck component attaches directly to a stem component that inserts into the bone, and a body component that also inserts into the bone is attached to the neck component and/or to the stem component. Methods for assembling the prosthesis are also provided, wherein the stem component is inserted within the body component, and the stem component is joined to the neck component. The prosthesis may be constructed from the components outside of the patient, or, components of the prosthesis may be inserted into the patient prior to final assembly of the prosthesis during surgery.
