Abstract
A wrist prosthesis has first, second, and third components that in one form are a radial component, a metacarpal component, and a bearing component. The bearing component is non-fixed or non-stationary relative to one of the radial component and the metacarpal component when the wrist prosthesis is assembled such as when implanted into a patient. As such, in one form a rotational joint or union is provided on the radial component and the bearing component. The bearing component is thus free to rotationally ride on the radial component, preferably 360.degree. thereabout. Distal the radial component, the bearing component includes an articulation surface. The metacarpal component includes an articulation surface that is complementary to the articulation surface of the bearing component. In this manner, the metacarpal component correspondingly moves relative to the bearing component. The bearing component is preferably made of a polymer such as polyethylene.
