ABSTRACT:
A modular prosthesis includes a component having a superior surface and an inferior surface. An elongate aperture having a major axis and a minor axis is defined in the component and a bolt shank is insertable through the elongate aperture in the component to extend beyond the inferior surface thereof. Means are provided for selectably positioning the bolt at one of a number of selected points along the major axis of the elongate aperture. In an illustrated embodiment, the means for positioning the bolt includes more than one seat for a bolt head about the aperture. In another embodiment, the prosthesis includes an adapter having a first end defining a cavity for receiving the shank of the bolt extending from the inferior surface. The adapter includes teeth on the first end that are engagable with at least one or more teeth near the aperture in the component on its inferior surface to fix the cavity, and thus the bolt, at a selected point along the major axis of the aperture. Exemplary prostheses include femoral and tibial components.
