ABSTRACT:
An endoprosthetic device for a prosthesis between metatarsal and phalangeal bones comprising proximal and distal components which are engageable with each other. The proximal component has a convex, part-spherical bearing surface and a stem projecting from this surface for securing the proximal component into the end of the first metatarsal. The distal component has a concave, part-spherical bearing surface and a stem projecting from this surface for securing the distal component into the end of the phalanx adjacent to the first metatarsal. The engagement of the two components forms a less-than-hemispherical articulation.
