CARPOMETACARPAL PROSTHESIS SYSTEM AND METHOD OF USING SAME

摘要

A carpometacarpal prosthesis system generally includes a trapezial implant for replacing an excised trapezium within a human hand and a component stem implant for replacing a partially excised first metacarpal. The component stem implant is adapted to be press fit within the medullary cavity of the partially excised first metacarpal bone of the human hand; the component stem when so implanted is adapted to effect universal movement of the first metacarpal bone relative to the trapezial implant thereby providing a restructured thumb metacarpal joint that restores substantially normal thumb function in terms of strength and flexibility.
