Abstract

L'invention concerne un clou d'ostéosynthèse pour le traitement chirurgical de fractures osseuses, lequel comprend, dans au moins une partie, une matière à mémoire de forme. Après activation de la matière à mémoire de forme, le clou forme un moyen de fixation. L'invention concerne également un procédé de production d'un clou d'ostéosynthèse comprenant une matière à mémoire de forme dans au moins une partie, procédé selon lequel le clou est déformé de façon à prendre la forme d'une moyen de fixation, la forme obtenue par déformation est maintenue mécaniquement, et le clou est chauffé pour qu'il garde sa forme. L'invention concerne également un moyen de maintien utilisé pour que le clou conserve sa forme de moyen de fixation pendant l'opération de chauffage.
