A body joint endoprosthesis includes an anchoring member having a shaft anchored in a first bone and a pivot member connected to the anchoring member by a pivot joint. The pivot member includes a first body joint member and a support element that bears against a seating surface of the first bone. The first body joint member and a second body joint member, connected to the second bone, form the body implant joint.

Body joint endoprosthesis

A surgical implant is produced by coating a metallic substrate with enamel. The metallic substrate provides structural strength and the enamel provides chemical stability, resistance to wear, tissue compatibility, progressive ingrowth and electrical insulating properties. The implant may be produced by coating a portion of the metallic substrate with a partially crystallized enamel, and then positioning the implant on a firing support with the partially crystallized enamel in contact with the support and coating the remaining non-enamelled surface.
