Die Erfindung betrifft eine Verbindungsvorrichtung für gelenknahe Knochenbrüche mit einem von der Seite in den Gelenkkopf einzuführenden Verbindungsglied, z. B. einer Schraube, und einer dieses Glied längsbeweglich führenden Einsatzhülse, die zum Befestigen am benachbarten Knochenstück einen starren kurzen Tragarm aufweist, der mit diesem Knochenstück durch ein ungefähr rechtwinklig zum Verbindungsglied gerichtetes Stützglied fest verbunden werden kann, nach Patent 918 531.The invention relates to a connecting device for joint-near fractures with one of the Side to be inserted into the joint head connecting member, z. B. a screw, and one of this link Insert sleeve that is longitudinally movable and has a rigid insert for attaching it to the adjacent piece of bone has short support arm, which with this piece of bone through an approximately perpendicular to the connecting member directional support member can be firmly connected, according to patent 918 531.

Die Erfindung besteht darin, daß der sich an den Röhrenknochen außen anlegende Tragarm der Einsatzhülse eine Hakenklaue trägt, die durch eine Bohrung der Knochenwand in den Knochenkanal eingreift. Durch das Verhaken des Tragarmes mit dem Röhrenknochen wird die Verbindung, besonders stabil. Man kann außerdem durch den Tragarm in den Röhrenknochen eine Schraube eindrehen, die zur Stabilisierung besonders dann sehr erheblich beiträgt, wenn sie auch die in den Knochenkanal ragende Hakenklaue erfaßt. Aber auch ohne diese. Schraube kann man der Klaue besonders guten Halt im Knochenkanal geben, wenn man sie so weit zurückbiegt, daß sie sich mit dem zurückgebogenen Ende auf der Seite der Einführungsbohrung von innen gegen die Knochenwand legt.The invention consists in that the support arm of the insert sleeve resting on the outside of the tubular bone carries a hooked claw which engages in the bone canal through a hole in the bone wall. The connection becomes particularly stable through the hooking of the support arm with the tubular bone. You can also screw a screw into the long bone through the support arm, which is used to Stabilization makes a particularly significant contribution when it also extends into the bone canal Hook claw captured. But even without this. The claw has a particularly good hold in the screw Provide a bone canal if you bend it back so far that the bent-back end opens up the side of the insertion hole from the inside against the bone wall.

Die Zeichnung stellt in Fig. 1 und 2 zwei Ausführungsbeispiele einer erfindungsgemäß ausgeführten Verbindungsvorrichtung für einen gebrochenen Oberschenkelhals dar.The drawing shows, in FIGS. 1 and 2, two exemplary embodiments of one designed according to the invention Connection device for a broken femoral neck.

Gemäß Fig. 1 dient, wie beim Hauptpatent, zur Verbindung der Knochenbruchstücke eine Schraube 15, die durch eine von außen in eine Aufbohrung des Schenkelknochens eingeführte Hülse 11 eingeschraubt ist, Die Hülse 11 wird durch einen von außen auf den Schenkelknochen dicht aufgelegten Tragarm 6 festgehalten. Der hakenförmige Tragarm hat am freien unteren Ende eine Klaue 60, die ungefähr parallel zur Hülse 11 verläuft und durch eine entsprechend gerichtete Bohrung 24 der Knochenwand in den Knochenkanal eingeschoben wird, Durch den Tragarm 6 und einen an ihm angeordneten schrägen Nocken 21 geht eine etwa rechtwinklig zur Hülse 11 verlaufende Schraube 22, die mit ihrem Gewindeteil 22a in eine Gewindebohrung der Klaue 6σ eingreift. Die Hülse 11 wird durch das Zusammenwirken der Schraube 22 und der sich in der Knochenbohrung 24 führenden Hakenklaue 6 a besonders sicher in Stellung gehalten.According to FIG. 1, as in the main patent, a screw is used to connect the bone fragments 15, which is screwed through a sleeve 11 inserted from the outside into a bore in the thigh bone The sleeve 11 is held in place by a support arm 6 which is placed tightly on the thigh bone from the outside. The hook-shaped support arm has a claw 60 at the free lower end, which is approximately parallel to the Sleeve 11 extends and through a correspondingly directed bore 24 of the bone wall in the Bone canal is inserted through the support arm 6 and an inclined one arranged on it Cam 21 is an approximately at right angles to the sleeve 11 extending screw 22, which with its threaded part 22a engages in a threaded hole in the claw 6σ. The sleeve 11 is through the interaction of the Screw 22 and the hook claw 6 a leading in the bone bore 24 are particularly securely in position held.

Bei der Bauart gemäß Fig. 2 ist der Tragarm 6 der Hülse 11 gerade und von U-förmigem Querschnitt und nimmt zwischen den U-Schenkeln ein hakenförmiges Zugglied 6' auf, das mit ihm durch eine zur Schraube 15 parallele schräge Schraube 23 verbunden ist, die Verbindungsvorrichtung für gelenknahe KnochenbrücheIn the design according to FIG. 2, the support arm 6 of the sleeve 11 is straight and has a U-shaped cross section and takes a hook-shaped tension member 6 'between the U-legs, which with him through a to the screw 15 parallel oblique screw 23 is connected, the connecting device for fractures near the joint

Die Klaue & α des Zuggliedes 6' greift durch die etwa rechtwinklig zu den Schrauben 15 und 23 gerichtete schräge Bohrung 24' des Schenkelknochens in den Knochenkanal ein und legt sich unterhalb der Bohrung 24' mit dem zurückgebogenen freien Ende 6' b an die Kanalwand an. Dadurch wird beim Anziehen der Schraube 23 verhindert, daß das durch sie gehaltene Zugglied 6' infolge der schrägen Führung in der Knochenbohrung 24' aus dieser herausgleiten kann.goes through a rear nose 6'c of the tension member 6 '. The claw & α of the tension member 6 'engages through the oblique bore 24' of the thigh bone, which is approximately at right angles to the screws 15 and 23, in the bone canal and rests below the bore 24 'with the bent-back free end 6'b on the canal wall . As a result, when the screw 23 is tightened, the tension member 6 'held by it is prevented from sliding out of the bone bore 24' as a result of the oblique guidance in the latter.
