Title (EN) VITAL TISSUE FOR TENDON OR LIGAMENT AND PROCESS FOR PRODUCING THE SAME
(FR) TISSU VITAL POUR TENDON ET LIGAMENT ET PROCEDE DE PRODUCTION CORRESPONDANT
Abstract:
(EN) A vital tissue for tendon or ligament which is expected as contributing to the rapid postoperative fixation to bone and early recovery owing to the high biocompatibility. Namely, a vital tissue for tendon or ligament comprising a tendon or ligament tissue base and a calcium phosphate compound wherein the calcium phosphate compound is fixed at least to the surface of the tendon or ligament tissue base; and a process for producing a vital tissue for tendon or ligament which involves the step of immersing the base alternately in a calcium solution and in a phosphoric acid solution to thereby form and fix the calcium phosphate compound.
(FR) L'invention concerne un tissu vital pour un tendon ou un ligament sensé contribuer à la fixation postopératoire rapide aux os et un rétablissement rapide grâce à une biocompatibilité élevée. Un tissu vital pour un tendon ou un ligament comprend notamment une base de tissu de tendon ou de ligament et un composé de phosphate de calcium, ce composé étant fixé à au moins la surface de la base de tissu de tendon ou de ligament. L'invention concerne également un procédé de production d'un tissu vital pour un tendon ou un ligament, qui consiste à immerger la base, en alternance, dans une solution de calcium et dans une solution à base d'acide phosphorique, de manière à former et à fixer le composé de phosphate de calcium.
