Description
Der Kyallendrueknagel für Schenkelhalsbrüche hat den Zweck, einen Knoch&nbruch am Sehenkelhaie fest und drehsicher zusammenzuziehen und dadurch die Hellselt zu verkürzen, sowie Falschgelenkbildung zu verhindern« Dasselbe gilt für die Yersteifung des Hüftgelenkes. Bis jetzt war es nicht möglich einen dünnen Hagel im abgebrochenen Schenkelhalskopf bis 5 cm auseinandersuspreizen. Dadurch wird der abgebrochen· Schenkelhalskopf fest ergriffen und kann nun durch Anziehen der Mutter (h1 oder h2) an den Bruch herangepreßt werden. Bach Heilung werden die Krallen In das Fünrungsgehäuae (c) zurückgeholt und der Jagel herausgenommen. The purpose of the Kyallendrueknagel for femoral neck fractures is to pull together a bone fracture on the ossicular shark firmly and securely, thereby shortening the hellselt and preventing the formation of the false joint «The same applies to the stiffening of the hip joint. Until now it was not possible to spread a thin hailstones in the broken head of the femoral neck by up to 5 cm. As a result, the broken-off femoral neck head is firmly gripped and can now be pressed against the break by tightening the nut (h1 or h2). Bach healing, the claws are brought back into the funnel housing (c) and the Jagel removed.
Durch Drehen der Zug- und Druekmutter (a), die nach Torn und hintern im Führungegehäuse (·) drehbar gelagert ist und gleichseitiges Testhalten des Tierkantes (f) hinten, schiebt sich das Gewinde-Tührungskrallenteil (b) ein Stück durch das Führungsgehäuse (e) naeh rom und schiebt die Erallen (die aneinandergelegt sich selbst abstützend in der Kitte des Führungsgehäuses (e) so liegen, dal In 4er Mitte immer ein fast viereckiges Loch bleibt) über eine Gleitbahn aus dem Führungegehäuse (e) durch die. Löcher (d) · Dabei dringen die Xrallen in die Sponglosa (Innere des Knochens) mit der Kraft eines Gewinde·· Dieser Vorgang findet an der Cortlkalie (θ) (ta· lufiere des Knochens), In welche die Xrallen eindringen, sein Bode mit Hilfe von löntgenbeobaohtung. Der altbekannte Kirschnerbohrdraht wird herausgezogen. Jetzt wird auf das hintere Xnde (f), (welches von der Mitte bis hinten ein Gewinde besitzt, das durch 4 gefräste Flächen fast viereckig (f) ist und zwar so, daß an de« Kanten immer noch genug Gewinde bleibt), eine verschiebbare Spannzange (g) auf den Tierkant geschoben, die mit einer Mutter (h2) fest verschlossen werden kann, wenn die beiden Bastteile (1) im Knochen (e) sich festgekrallt haben. Dadurch sind beide Teile des Knochen· - vorn durch die Xrallen (b), hinten durch die Spannzange (β) ~ gegen Drehung gesichert. Beim Anziehen der Mutter (h2) federn die Krallen etwas und erzeugen so die federnd· Kompression an der Bruchstelle (i). Da vielfach der Knoehenschaft durch Unfall autfe ajpch zerbricht, muß das bekannt· Terfahren der Lasche (k) a*- geweflÄet werden, die an den Knochen angeschraubt wird und dl· Irttche zusammenzieht·By turning the push and pull nut (a), which is rotatably mounted in the guide housing (·) towards the end and back, and holding the animal edge (f) at the back, the threaded guide claw part (b) pushes a little through the guide housing (e ) naeh rom and pushes the erallen (which put themselves together supportive in the cement of the guide housing (e) so that In 4 in the middle always remains an almost square hole) via a slide from the guide housing (e) through the. Holes (d) · The Xrallen penetrate the sponglosa (inside of the bone) with the Force of a thread This process takes place at the cortex (θ) (Ta · run the bone), into which the Xrallen penetrate Bode with the help of x-ray observation. The well-known Kirschner wire is pulled out. Now on the rear end (f), (which has a thread from the middle to the back, which is almost square (f) due to 4 milled surfaces in such a way that the « Edges still enough thread remains), a sliding collet (g) pushed onto the animal edge, which is secured with a nut (h2) can be tightly closed when the two bast parts (1) in the Bone (s) have clung to it. This means that both parts of the Bones - secured against rotation at the front by the Xrallen (b), at the rear by the collet (β) ~. When tightening the nut (h2) the claws spring a little and thus generate the resilient compression at the break point (i). Often due to an accident autfe ajpch breaks, it must be known that the tab (k) a * - be flattened, which is screwed to the bone and pulls the table together
