First tests on Al2O3 – Al2O3  articulation : Biology, tribology.

First implantation of our 2C HERMES, a total knee prosthesis which both cruciates remain intact.

HERMES Patellofemoral first implantation.

Europeen patent for our cervical disc prosthesis, CERADISC.

First implantation of our posterior stabilized knee prosthesis, HERMES PS.

First implantation of our CERAFIT metal cup using the “triradius” concept.

World’s first implant of a cement-free metal cup in titanium alloy for a hip prosthesis with an alumina ceramic core, a solution subsequently adopted by all the world’s major laboratories.

Discovery of the potential of the titanium alloy TiAl6V4 by Daniel Blanquaert. Dr Pierre Boutin performed the world’s first implantation of a hip with a femoral stem made of titanium alloy TiAl6V4. This material went on to become the reference and is universally used in…

Premiers essais sur le frottement Al2O3 – Al2O3  : Biologie, tribologie

Dr Pierre Boutin performed the world’s first total hip prosthesis with an alumina-alumina articulation. This component presents very low wear and friction characteristics – essential parameters in the design of joint prostheses. Perfectly biotolerant, this component went on to become the reference for…
