Abstract: An improved body element for use in a modular prosthetic stem component of the sort comprising a body element and at least one other element, wherein the body element and the at least one other element are joined together by at least one modular connection, wherein the improved body element comprises an anterior wall and a posterior wall, at least one of the anterior wall and the posterior wall converging toward the other on the medial side of the body element and diverging away from the other on the lateral side of the body element, whereby the body element approximates a general wedge shape.

Abstract: A prosthetic femoral stem component comprising a body element, a neck element and a stem element, with the body element, neck element and stem element being secured to one another with a modular connection, wherein the modular connection comprises a taper junction and an engaged-fit junction.

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.

Abstract: A nonconstrained, total great toe joint implant for the metatarsophalangeal joint made of a first component with a convex, partially spherical surface ending in a rear surface from which a longitudinally asymmetric implantation stem projects and having a flange on the dorsal side of the implant which extends the convex surface past the rear surface. The rear surface is inclined 10.degree. relative to a normal plane which intersects this surface. The metatarsal bone is resected accordingly. The phalangeal implant component is made of a base with a stem for placement in a bone cavity, projecting from a rear side thereof and having a low-friction, concavely curved insert affixed to the base which slidably engages and cooperates with the convex surface of the metatarsal implant component.
