Description
Die Neuerung bezieht sich auf ein OsteosynthesehiLfsmitteL nach den Merkmalen des Oberbegriffs des Anspruchs 1.The innovation relates to an osteosynthesis aid according to the features of the preamble of claim 1.
Es ist bekannt, Frakturen des OberschenkeLhaLses bzw. des Subtrochanters mit Hilfe einer Lasche zu versorgen, die lateral gegen den Femur geschraubt wird. Die Lasche weist eine Hülse auf, durch die eine Schenkelhalsschraube hindurchgeführt ist. Ein derartiges Osteosynthesehi I fsmitteL, das auch als Pohl'sche Lasche bekannt ist, hat sich int Prinzip bewährt. Die Befestigung der Lasche kann indessen zu einer Schwächung des Femurs führen. Ferner ist ein umfangreicher operativer Eingriff erforderlich, um eine derartige Lasche anzubringen*It is known that fractures of the femoral neck or subtrochanter can be treated using a tab that is screwed laterally against the femur. The tab has a sleeve through which a femoral neck screw is passed. Such an osteosynthesis device, also known as a Pohl's tab, has proven itself in principle. However, attaching the tab can lead to a weakening of the femur. Furthermore, extensive surgical intervention is required to attach such a tab*

Es ist daher auch bereits vorgeschlagen Worden, zur HaL-tttfrung einer Schenkelhalsschraube einen VerriegeLungsnagel zu Verwenden CDE-Gm 86 20 399.1). Verriegelungsnägel sind an sich bekannt und werden zur Versorgung von Brüchen, zum Beispiel im Oberschenke I- und Unterschenkelbereich, verwendet. Ein VerriegelungsnageL ist verhältnismäßig biegesteif und füllt nahezu den Märkraum eines Knochens aus. Er besitzt mehrere Querbohrungen, durch die Knochenschrauben hindurchgeführt werden, um den Verriegelungsnagel beidseitig der Fraktur im Knochen fest zu verankern ("zu verriegeln"). Bei der Versorgung von subtrochanteren Frakturen ist der VerriegelungsnageL mit einer Querdurchbohrung vorgesehen für die Aufnahme einer SchenkeLhaLsschraube. Hier dient der VerriegelungsnagelIt has therefore already been suggested that a locking nail be used to hold a femoral neck screw (CDE-Gm 86 20 399.1). Locking nails are known per se and are used to treat fractures, for example in the upper and lower leg areas. A locking nail is relatively rigid and almost fills the bone space. It has several transverse holes through which bone screws are passed in order to firmly anchor ("lock") the locking nail in the bone on both sides of the fracture. When treating subtrochanteric fractures, the locking nail is provided with a transverse hole to accommodate a femoral neck screw. Here the locking nail is used
daher nicht zur Frakturversorgung selbst, sondern zur Führung und Halterung der SchenkelhaLsschraube. Der Verri ege lungsnageL braucht daher Lediglich im distalen Bereich Querdurchbohrungen aufzuweisen, um den Nagel axial und in Drehrichtung festzulegen. Die SchenkeLhaLsschraube sitzt vorzugsweise passend in der schrägen Durchbohrung.

The locking nail therefore only needs to have transverse holes in the distal area in order to fix the nail axially and in the direction of rotation. The femoral neck screw preferably fits snugly in the oblique hole. The femoral neck screw is therefore secured against pivoting both in the plane it spanned and around an axis that runs through the locking nail.

It is usually between 135 and 145 . For optimal treatment, a considerable number of locking nails with different diameters and different positions of the oblique - To keep drilling in stock.
Der Neuerung liegt daher die Aufgabe zugrunde, ein Osteo-Synthesehilfsmittel zur Versorgung von subtrochanteren Frakturen zu schaffen, das mit geringerem Aufwand eine Anpassung an den jeweiligen Schenkelhalswinkel erlaubt.The innovation is therefore based on the task of creating an osteo-synthesis aid for the treatment of subtrochanteric fractures, which allows an adaptation to the respective femoral neck angle with less effort.
Diese Aufgabe wird durch die Merkmale des Kennzeichnungs-K teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

neuerungsgemäßen OsteosynthesehiLfsmittel kann daher der jeweils passende VerriegeLungsnageL verwendet werden,während das jeweilige Aufsatzstück danach gewählt wird, welchen Schenkelhalswinkel der zu versorgende Patient hat. Vorteilhaft ist ferner, daß die Handhabung des Erfindungsgegenstandes mit den gleichen Mitteln erfolgen kann wie die des Verriegelungsnagels.The appropriate locking nail can therefore be used with the innovative osteosynthesis aid, while the respective attachment is selected according to the femoral neck angle of the patient to be treated. It is also advantageous that the object of the invention can be handled using the same means as the locking nail.
Mit der Verriegelungsnagelungstechnik vertraute Chirurgen können daher auch ohne zusätzliche SchuLungsmaßnahme die Erfindung einsttzen.Surgeons familiar with the locking nailing technique can therefore use the invention without additional training.
Bei einer Ausgestaltung der Neuerung ist vorgesehen, daß das proximate Ende des VerriegelungsnageLs etwas konisch aufgeweitet und im Querschnitt oval geformt ist und unterhalb des aufgeweiteten Endabschnitts ein Innengewinde vorgesehen ist und daß ein distaler Endabschnitt des Aufsatzstücks komplementär zum Endabschnitt des Verriegelungsnagels geformt ist und an einer annähernd radialen Schulter endet. Mit Hilfe der im Querschnitt ovalen Ausführung des distalen Endes des VerriegeLungsnagels läßt sich dieser mit Hilfe eines eingeschraubten Einschlagwerkzeugs in die gewünschte Drehlage bringen. Das distale Ende des Aufsatzstücks ist komplementär geformt, so daß beim Aufbringen einer Drehkraft auf das Aufsatzstück der VerriegelungsnageL ebenfalls nach Möglichkeit ohne Lose mitgedreht wird. Das proximate Ende des Verri egelungsnagels Liegt gegen die radiale Schulter an, wobei nach Möglichkeit ein gLätter übergang zum Aufsatzstück hin stattfindet, das in diesem Bereich vorzugsweise konisch geformt ist*In one embodiment of the innovation, it is provided that the proximal end of the locking nail is slightly conically widened and oval in cross-section and an internal thread is provided below the widened end section and that a distal end section of the attachment piece is shaped complementarily to the end section of the locking nail and ends at an almost radial shoulder. With the help of the oval cross-section of the distal end of the locking nail, it can be brought into the desired rotational position with the help of a screwed-in impact tool. The distal end of the attachment piece is shaped complementarily so that when a rotational force is applied to the attachment piece of the locking nail, it is also rotated as far as possible without any slack. The proximal end of the locking nail rests against the radial shoulder, with a smooth transition to the attachment piece taking place if possible, which is preferably conically shaped in this area*

Der VerriegeLungsnageL kann auf diese Weise fest gegen das Aufsatzstück gespannt werden. Der Kopf der Verbindungssch.aube ist zweckmäßigerweise zyLindrisch geformt mit einem Außendurchmesser, der nur etwas geringer ist als der der Durchbohrung in diesem Bereich.A connecting screw is used which is screwed into the internal thread of the locking nail, which is usually provided in the proximal end. In this way, the locking nail can be firmly clamped against the attachment piece. The head of the connecting screw is conveniently cylindrical in shape with an external diameter which is only slightly smaller than that of the cannulation in this area.
Die Gesamtlänge des Aufsatzstücks, die für alle Anwendungsfälle gleich sein kann, ist so bemessen, daß zwischen dem pr«; xima Len Ende des Verriegelungsnagels und dem unteren Ende der schrägen Durchbohrung noch ausreichend Raum bleibt, wodurch die Durchbohrung erheblichen Kräften ausgesetzt werden kann, ohne daß es zu Verformungen kommt.The total length of the attachment, which can be the same for all applications, is dimensioned so that there is still sufficient space between the pr«; xima Len end of the locking nail and the lower end of the oblique perforation, whereby the perforation can be subjected to considerable forces without deformation occurring.
Eine weitere Ausgestaltung der Neuerung sieht vor, daß im Bereich der Schrägdurchbohrung die Schenkelhalsschraube am Umfang mehrere achsparallele in Umfangsrichtung beabstandete Nuten aufweist, in die ein in das proximate Ende des Aufsatzstücks einsetzbarer Verriegelungsstift eingreift. Der Verriegelungsstift wird vorzugsweise in das Aufsatzstück versenkt eingeschraubt. Zu diesem Zweck hat das proximate Ende des Verriegelungsstifts einen Innensechskant, ebenso wie die Verbindungsschraube zwischen Äufsatzstück und Verriegelungsnaget.A further embodiment of the innovation provides that in the area of the oblique drilling, the femoral neck screw has several axially parallel grooves spaced apart in the circumferential direction, into which a locking pin that can be inserted into the proximal end of the attachment piece engages. The locking pin is preferably screwed countersunk into the attachment piece. For this purpose, the proximal end of the locking pin has a hexagon socket, as does the connecting screw between the attachment piece and the locking pin.
