Patent ID: 8192503

Claim:
An adapter assembly for mechanically coupling prosthetic components, the adapter assembly comprising: a generally hollow and generally cylindrical female element including an outer surface including exterior threads configured to operatively engage an internally threaded surface proximate to a distal end of a socket adapter, an upper portion including a lip projecting inwardly from an interior surface, and a lower portion including a concave surface configured to conformally engage a convex top surface of a prosthetic; and a generally cylindrical male element including an outer surface including exterior threads configured to operatively engage an internally threaded surface of the prosthetic, a substantially flat upper portion including a lip projecting outwardly from the outer surface and configured to engage the lip of the female element and to compress the lower portion of the female element against the top surface of the prosthetic; wherein an outer diameter of the exterior threads of the male element is smaller than an interior of the female element such that the exterior threads of the male element are able to pass through the female element without threadingly engaging any internal surface of the female element, and when the lip of the male element engages the lip of the female element, a top surface of the male element is flush with a top surface of the female element and the externally threaded surface of the male element extends below a bottom surface of the female element.
