LARGE TAPER MODULAR SHOULDER PROSTHESIS

摘要

PROBLEM TO BE SOLVED: To provide a light structure for joint prosthesis. SOLUTION: A kit for assembly of a modular joint prosthesis includes at least two shank/body elements sized for insertion into the shank of the bone and at least two head members sized to replace one bearing surface of the joint. Each shank/body element has a collar that has a shallow width and a circular plan view and that is formed to overhang a resected level of the bone. The collar has a male taper on its side wall. Each head member has a first geometric axis therethrough and defines a part spherical cavity with a skirt extending about the cavity. The skirt provides a female taper for receiving and providing a mechanical connection with the male taper on the side wall of each collar. A second axis extends through the skirt. The first axis and second axis may be coincident or offset from one another. COPYRIGHT: (C)2006,JPO&NCIPI
