Abstract:
A system for long bone arthroplasty includes humeral head prosthesis components, and an array of humeral head prosthesis components, each humeral head prosthesis component in the array having a convex articulation surface that is hemi-elliptical and defined by a major axis, a minor axis, an apex, and a base having an elliptical cross sectional shape defined by a major diameter along the major axis and a minor diameter along the minor axis, wherein the array of elliptical humeral head prosthesis components provides for suitable and sufficient anatomical fit within a variation of up to and not more than 3 mm in at least 96% of a patient population, and up to 99% of a patient population.

Claim (Index 15):
An arthroplasty assembly comprising:\n a prosthesis component and a coupler component engageable to provide an arthroplasty assembly, wherein the position of the prosthesis component can be varied rotationally around a shared central engagement axis with the coupler component,\n the prosthesis component selected from an array comprising a plurality of humeral head prosthesis components that (i) vary from one another in their major diameters in a range from about 1 to 4 mm, and (ii) vary from one another in at least one of minor diameter, humeral head height (HHH), ROCF and ROCS as a function of DF, wherein each humeral head prosthesis component in the array has a convex articulation surface that is hemielliptical and is defined by a major axis (corresponding to a frontal plane) and a minor axis (corresponding to a sagittal plane), a major diameter (DF) along the major axis and a minor diameter (DS) along the minor axis, and radii of curvature along the major axis (ROCF) and along the minor axis (ROCS), each prosthesis component comprising an apex and a base each having an elliptical cross sectional shape \n the coupler component comprising a prosthesis component engagement side and an opposite side comprising a bone contact surface, the sides bounded by a lateral edge that is one of cylindrical, frustoconical and frustohemispherical, \n wherein, when one of the selected prosthesis and coupler components are engaged and the coupler component is recessed into bone, rotation of the prosthesis component within the coupler component provides alignment of the bone articulation surface of the prosthesis component with the bone that is anatomically similar to a native long bone.
