<p>This intracortical implant (3), especially for attaching ligaments to bony tissues, is made of a thermal elastic martensitic alloy whose transformation temperatures are: - martensite transformation temperature Ms lower than 5 DEG C, - austenite transformation temperature As higher than 15 DEG C. It is trained to adopt the form of a U-shaped pin whose two arms (5) are parallel at a temperature below the martensite transformation temperature of the material of which it is made, the said arms moving away from their original position at a temperature above the austenite transformation temperature of the said material, so as to come into interaction with the inner face of the cortical bone of the bony tissue. <IMAGE></p> |
