摘要： A trapezium prosthesis is provided which includes a body having a frustocylindrical shape, the frustocylindrical shape including a frustum and an oppositely disposed planar base, the frustum being canted relative to a planar base. The prosthesis may be made of a swellable fluid absorbing polymer which imparts flexibility and/or resiliency to the prosthesis. The swellable fluid absorbing polymer may also provide the surface of the prosthesis with lubricity. In embodiments, the prosthesis has a first configuration and a second configuration, the first configuration being of reduced size relative to the second configuration. The prosthesis may also include a reinforcement member. In embodiments, the prosthesis includes a stem projecting outwardly from the frustum.
