Beschreibung
Zusammenfassung:	A kit for assembly of a modular joint prosthesis ( 10 ) includes at least two shank/body elements ( 22/20 ) sized for insertion into the shank of the bone and at least two head members ( 48 ) sized to replace one bearing surface of the joint. Each shank/body element ( 22/20 ) has a collar ( 58 ) that has a shallow width and a circular plan view and that is formed to overhang a resected level of the bone. The collar ( 58 ) has a male taper on its side wall ( 64 ). Each head member ( 48 ) has a first geometric axis ( 52 ) therethrough and defines a part spherical cavity ( 49 ) with a skirt ( 66 ) extending about the cavity ( 49 ). The skirt ( 66 ) provides a female taper for receiving and providing a mechanical connection with the male taper on the side wall ( 64 ) of each collar ( 58 ). A second axis extends ( 55 ) through the skirt ( 66 ). The first axis ( 52 ) and second axis ( 55 ) may be coincident or offset from one another.
