A prosthesis (10) for a joint includes a stem (12) for engagement with a bone. The stem includes a surface (15) defining a bore (16). The prosthesis further includes a joint component (14). The joint component includes a bearing surface (19) for articulating engagement with at least one of a natural opposing joint component and a prosthetic opposing joint component. The prosthesis further includes a mounting element (30). The mounting element includes a proximal portion (33) for engagement with the joint component and further includes a substantially solid articulating portion (34) having a contiguous periphery. The substantially solid articulating portion is configured to facilitate articulating movement of the substantially solid articulating portion within the bore when the contiguous periphery is not forcefully engaged with the bore, and the substantially solid articulating portion and the bore are configured to fixedly couple the mounting element to the stem when the contiguous periphery is forcefully engaged with the bore. |
