Abstract
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.
Claims8
a metallic hip joint prosthesis at least partially coated with enamel, comprising a transition part having a recess, an anchoring part having a guide pin which is inserted in said recess, said transition part being fastened to said anchoring part with a securing screw which is screwed into said guide pin, and a ball connected to said transition part, said ball being adapted to cooperate with a socket.
A metallic vertebra prosthesis at least partially coated with enamel, comprising:
- two parts interconnectible with each other substantially along the main longitudinal plane of the prosthesis, each of said parts comprising:
- two connecting portions connectible to adjacent vertebrae, each of said connecting portions having a platform adapted to face the end of an adjacent vertebra and at least one projection adapted to engage a lateral surface of the vertebra;
- and
- a connecting limb between the two connecting portions of said part.
