Title
(DE) VERRIEGELUNGSEINRICHTUNG FÜR EINEN GEBROCHENEN ODER ANGEBROCHENEN KNOCHEN
(EN) BLOCKING DEVICE FOR A BROKEN OR CRACKED BONE
(FR) DISPOSITIF DE VERROUILLAGE POUR UN OS CASSE OU FELE
Abstract
(DE)
Verriegelungseinrichtung für einen gebrochenen oder angebrochenen Knochen, bestehend aus einem Marknagel, der einen proximalen Abschnitt, der Perforationen haben kann, und einen distalen Abschnitt aufweist und mindestens einer Verriegelungshilfe, dadurch gekennzeichnet, dass der distale Abschnitt eine Oberflächenstruktur aufweist, die so ausgebildet ist, dass mittels des Marknagels den Knochen durch die von außen durch den Knochen auf die Oberflächenstruktur des Nagels einwirkende mindestens eine Verriegelungshilfe vorzugsweise gegenüber Rotation und/oder axialer Belastung stabilisierbar ist.
(EN)
Disclosed is a blocking device for a broken or cracked bone, comprising at least one blocking aid and an intramedullary nail which is provided with a distal section and a proximal section that can encompass perforations. The inventive blocking device is characterized in that the distal section has a surface structure which is configured such that the bone can be stabilized preferably against rotation and/or axial stress by means of the intramedullary nail using the at least one blocking aid that acts upon the surface structure of the nail from outside through the bone.
(FR)
L'invention concerne un dispositif de verrouillage pour un os cassé ou fêlé, comprenant un clou intramédullaire, pourvu d'un segment proximal pouvant être perforé et d'un segment distal, ainsi qu'au moins un élément auxiliaire de verrouillage. L'invention est caractérisée en ce que le segment distal a une structure superficielle conçue de telle sorte que le clou intramédullaire permet de stabiliser l'os, de préférence relativement à la rotation et/ou à la sollicitation axiale, au moyen de l'élément auxiliaire de verrouillage agissant de l'extérieur sur la structure superficielle du clou en traversant l'os.
