Abstract
Implantat als Platzhalter zwischen zwei durch teilweise oder vollständige Abtrennung erzeugten Knochensegmenten, der Tibia und der Tuberositas, welches über mindestens zwei voneinander abgewandte Knochenkontaktflächen verfügt, dadurch gekennzeichnet, dass mindestens eine Knochenkontaktfläche einen Vorsprung aufweist, wobei mindestens ein Vorsprung die Geometrie eines längsgeteilten Zylinders (5, 6, 7, 8) aufweist und mindestens eine Knochenkontaktfläche (16, 17) gekrümmt ist, wobei die Knochenkontaktfläche in keinem Querschnitt dem Verlauf einer logarithmischen Spirale folgt.Implant as a spacer between two bone segments produced by partial or complete separation, the tibia and the tuberosity, which has at least two mutually remote bone contact surfaces, characterized in that at least one bone contact surface has a projection, wherein at least one projection of the geometry of a longitudinally divided cylinder (5 , 6, 7, 8) and at least one bone contact surface (16, 17) is curved, wherein the bone contact surface in no cross section follows the course of a logarithmic spiral.
Description
Eine Möglichkeit zur Versorgung von Kreuzbandrissen, speziell beim Tier, ist die Manipulation des Patellasehnen- und Muskelapparates. Hierzu wird die Tuberositas (
Ein wesentlicher Nachteil der auf dem Markt verfügbaren Implantate besteht in der Fixation des Implantates, welche nach bisherigem Stand der Technik mittels Schrauben, Pins, Zuggurten oder Spangen gelöst wird. Die benötigten Bohrungen für diese Fixationselemente schwächen jedoch den filigranen Knochen zusätzlich, so dass systembedingte Komplikationen ausgelöst werden können. Ein weiterer Nachteil ist der Mangel an einer soliden Verbindung zwischen dem Implantat und dem angrenzenden Knochen zur Aufnahme und Weiterleitung der entstehenden Zugkräfte, die auf die Tuberositas (
