Description

Innenschiene für Röhrenknochen Zusatz zum Patent 742097 Gegenstand der vorliegenden Erfindung ist eine besondere Ausführung der Innenschiene nach Patent 742 097, bei der die Schiene besonders leicht und billig wird. Diese Ausführung kennzeichnet sich dadurch, daß die Schiene als dünnwandiges Rohr aus elastischem Baustoff ausgebildet ist. Ein solches Rohr gestattet eine elastische Formänderung sowohl im Längsprofil (Biegung) als auch im Querschnitt. Diese Eigenschaft kant ausgenutzt werden, um der rohrförmigen Schiene in einem Knochenkanal Halt zu geben, der im Längs- oder Querprofil oder in beiden Profilen von ihr abweicht. Treibt man beispielsweise in einen ungefähr kreisrunden Knochenkanal eine aus elastischemBaustoff bestehende rohrförmige Schiene von elliptischem Ouerschnitt, dessen große Achse länger und dessen kleine Achse kürzer als der Kanaldurchmesser ist, mit entsprechendem Kraftaufwand, z. B. durch Hammerschläge, ein, so wird das elliptische Rohr in Richtung der großen Achse zusammengedrückt und in Richtung der kleinen Achse geweitet, also im Sinne einer Amläherung an die I(reisform des Kanals elastisch verformt, so daß es in Richtung der großen Achse mit Spannung an der Knochenkanalwand anliegt. Dadurch klemmt sich die Schiene im Knollen und stellt zugleich die beiden I(nochenbruchstücke in ihrer richtigen gegenseitigen Stellung fest.Inner splint for long bones Addition to patent 742097 subject The present invention is a particular embodiment of the patent inner rail 742 097, where the rail is particularly light and cheap. This execution is characterized by the fact that the rail is a thin-walled tube made of elastic Building material is formed. Such a tube allows an elastic change in shape both in the longitudinal profile (bend) and in the cross-section. This property cant be used to hold the tubular splint in a bone canal, which deviates from it in the longitudinal or transverse profile or in both profiles. One drifts for example in an approximately circular bone canal made of elastic building material existing tubular rail of elliptical cross-section, its major axis longer and whose minor axis is shorter than the channel diameter, with a corresponding Effort, e.g. B. by hammer blows, a, the elliptical tube is in the direction the major axis compressed and expanded in the direction of the minor axis, so elastically deformed in the sense of an approximation of the I (rice shape of the canal, so that it rests against the wall of the bone canal with tension in the direction of the major axis. Through this the splint clamps itself in the bulb and at the same time places the two I (fragments firmly in their correct mutual position.

Das Rohr kann an den Enden offen oder wenigstens am vorderen Ende geschlossen sein. Im ersten Falle schiebt es sich beim Einführen im wesentlichen mit seiner Wandung zwischen Isnocllenwand und Mark, das also in ihm hochsteigt. Dabei ist dem Rohr eine metallisch glatte Innenfläche zu geben. The tube can be open at the ends or at least at the front end be closed. In the first case, it essentially pushes itself during insertion with its wall between Isnocllenwand and Mark, which rises up in it. The pipe has to be given a metallically smooth inner surface.

Im zweiten Falle muß am vorderen Ende der Schiene eine ungefähr kegelförmige Spitze gebildet sein, z. B. durch Herausschneiden von Dreieckstüclien und Zusammenbiegen der stehenbleibenden Teile. Auf diese Weise kann man auch verhindern, daß durch den Abschluß die Querelastizität gestört wird. Ferner kann man durch eine besondere Querschnittsform für genügend weite äußere Kanäle sorgen, durch die das IR:nochenmark beim Einführen außerhalb der Schiene hochsteigen kann. Diesen Zweck erfüllt z. B. eine Dreieckform (gegebenenfalls mit abgerundeten Ecken), besonders wenn mindestens eine Dreieckseite kreisbogenartig nach innen gebogen ist, wodurch überdies die Bedingungen für eine elastische Formänderung des Querschnitts verbessert werden Älan kann, um bei vorn offenem Rohr dessen Au fn ah me raum für Knochenmark zu verkürzen bzw. zu vereinigen, auch auf das offene rückwärtige Ende des Rohres einen abnehmbaren Deckel setzen und diesen mit einem nach innen ragenden Ansatz versehen.In the second case, there must be an approximately conical shape at the front end of the rail Be formed tip, z. B. by cutting out triangular pieces and bending them together of the remaining parts. This way you can also prevent through the conclusion the transverse elasticity is disturbed. You can also go through a special Cross-sectional shape ensure sufficiently wide outer channels through which the IR: nochenmark can rise when inserted outside the rail. This purpose z. B. a triangular shape (possibly with rounded corners), especially if at least one side of the triangle is curved inwards like a circular arc, which also creates the conditions for an elastic deformation of the cross-section can be improved Älan to with the tube open at the front to shorten or reduce the space it holds for bone marrow to unite, also a removable one on the open rear end of the tube Place the lid and provide this with an inward protruding shoulder.
