    摘要: A joint prosthetic component that includes first (12) and second (14) arms, and a joint member (16) interposed therebetween. The joint member (16) is configured to permit flexion motion between the first (12) and second (14) arms, and includes a first concave surface (18) and a second concave surface (20). The first concave surface (18) has a plurality of arcuate portions (26,28) defined therein. The first (12) and second (14) concave surfaces are located on opposing sides of the joint member (16).

    摘要: 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° 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.
