Abstract
Description
Die Erfindung betrifft einen modularen proximalen Femurnagel, insbesondere für Oberschenkel- und Oberschenkelhalsfrakturen, wobei ein Marknagel im proximalen Bereich mehrere Öffnungen in gleicher Richtung und quer zur Mittelachse des Bereiches aufweist, wobei die Öffnungen zusätzliche Ausparungen als Verdrehsicherheit aufweisen und in diese Quernägel, Knochenschrauben und/oder dynamische Zugschrauben einsetzbar sind.The The invention relates to a modular proximal femoral nail, in particular for thigh and Femoral neck fractures, with an intramedullary nail in the proximal region several openings in the same direction and transverse to the central axis of the area, the openings additional Cutouts as anti-rotation have and in these cross nails, bone screws and / or dynamic lag screws can be used.
Derartige Femurnägel sind auch unter der Bezeichnung intramedulläre, intertrochantäre Frakturfixierungsnägel bekannt, beispielsweise in einer verbreiteten Version als „Gamma Nail" vielfach erprobt und als Implantat eingesetzt.such femoral nails are also known as intramedullary, intertrochanteric fracture fixation nails, for example, in a popular version called "gamma Nail "tested many times and used as an implant.
Durch
die
Nachteilig an vorgenannter Vorrichtung ist die Verwendung einer Hülse, denn prinzipiell genügt der Marknagel und ein ihn durchdringender Quernagel oder Querschraube. Auch das eine die Fraktur zusammenziehende Kompression angesetzt wird, ist nicht immer erwünscht, wobei es teilweise sogar erwünscht ist, dass die Querschraube im Marknagel längsverschiebbar ist.adversely to the aforementioned device is the use of a sleeve, because in principle, the suffice Intramedullary nail and a transverse nail or transverse screw penetrating it. Also, the one the fracture contracting compression set is not always desirable sometimes even desirable is that the transverse screw in the intramedullary nail is longitudinally displaceable.
Diese bekannten Vorrichtungen weisen weiterhin gewisse Nachteile auf, dass sie Querschrauben und/oder Knochenschrauben lediglich in Richtung der im Marknagel vorhandenen Bohrungen zulassen, obwohl es häufig erwünscht wäre, die Quernägel oder Knochenschrauben entsprechend des tatsächlich vorhandenen Frakturspaltes unter einem anderen Winkel einsetzten zu können.These known devices also have certain disadvantages, that they cross screws and / or bone screws only in the direction allow drilling in the intramedullary nail, although it would often be desirable, the cross nails or bone screws corresponding to the actual fracture gap to use at a different angle.
Die Erfindung hat sich deshalb die Aufgabe gestellt, einen Marknagel so auszubilden, dass eine größtmögliche Modularität in Bezug auf die verschiedensten möglichen Frakturverläufe im proximalen Bereich des Oberschenkels berücksichtig werden und gleichzeitig verschiedene Befestigungsarten, dynamisierend oder komprimierend, genutzt werden können.The The invention therefore has the task of an intramedullary nail form so that the greatest possible modularity in terms on the most diverse possible fracture gradients be taken into account in the proximal region of the thigh and at the same time various types of fastening, dynamizing or compressing, can be used.
Zur Lösung dieser Aufgabe wird ein Basis- Marknagel vorgeschlagen, in denn verschiedene Quernägel verdrehgesichert und lediglich formschlüssig einsetzbar sind, anstelle derer auch dynamische Zugschrauben verwendet werden können und weiterhin in Kombination mit den Quernägeln oder Zugschrauben auch zusätzliche Knochenschrauben einsetzbar sind. So können in die Öffnungen des Marknagels beispielsweise anstelle von Quernägeln Buchsen mit exzentrischen Bohrungen für Knochenschrauben eingesetzt werden, so dass unterschiedlich liegende Frakturspalte auf optimale Weise erfasst und fixiert werden können.to solution this task, a basic intramedullary nail is proposed in different cross nails secured against rotation and can only be used positively, instead which also dynamic lag screws can be used and still in combination with the cross nails or lag screws also additional Bone screws are used. So can in the openings of the intramedullary nail, for example, instead of cross nails jacks with eccentric Holes for Bone screws are used so that different lying Fracture cleft can be detected and fixed in an optimal way.
Weitere Vorteile ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen und werden anhand der Zeichnungen näher erläutert.Further Advantages will become apparent from the following description of exemplary embodiments and become closer with the help of the drawings explained.

die Quernägel
Die bereits erwähnte vorteilhafte Kombination zwischen dem Basis- Marknagel und der Nutzung der verschiedenen Quernägel ergibt eine sehr gute Modularität für die verschiedensten Frakturen, deren Lage und Ort.The already mentioned advantageous combination between the base intramedullary nail and the use of different cross nails gives a very good modularity for the various fractures, their location and location.
So können neben Quernägeln auch zusätzlich so genannte dynamische Zugschrauben verwendet werden, wenn beispielsweise eine Kompression erwünscht ist.So can next to cross nails also in addition so-called dynamic lag screws are used when, for example a compression desired is.
