Modulares Femurprothesensystem mit einem Schaft bzw. Prothesennagel, auf welchen verschiedene Module aufsetzbar sindModular femoral prosthesis system with a shaft or prosthetic nail on which various modules can be attached

Die Erfindung richtet sich auf einen Schaft bzw. Prothesennagel für ein modulares Femurprothesensystem aus Titan, insbesondere ein Revisionshüftprothesensystem, umfassend einen in den Oberschenkelknochen einschlagbaren Verankerungsabschnitt, einen den Verankerungsabschnitt verlängernden Verbindungsabschnitt und einen abgewinkelten Gelenkkugelabschnitt zum Aufsetzen der Gelenkkugel, wobei der Verbindungsabschnitt durch wenigstens ein über Konusabschnitte verbindbares Hülsen-Element gebildet ist, und wobei das Hülsen-Element eine durchgehende Längsbohrung aufweist, in welche von dem Gelenkkugelabschnitt her eine bis in den Verankerungsabschnitt reichende Sicherungsschraube einsetzbar ist, die in einen Innengewindeabschnitt des Verankerungsabschnitts eingreift.The invention is directed to a shaft or prosthetic nail for a modular femoral prosthesis system made of titanium, in particular a revision hip prosthesis system, comprising an anchoring section that can be driven into the femur, a connecting section that extends the anchoring section and an angled joint ball section for attaching the joint ball, wherein the connecting section is formed by at least one sleeve element that can be connected via conical sections, and wherein the sleeve element has a continuous longitudinal bore into which a locking screw can be inserted from the joint ball section that extends into the anchoring section and engages in an internal thread section of the anchoring section.

Ein derartiger gattungsgemäßer Schaft ist aus der DE 43 20 086 Al bekannt. Ein derartiger Schaft ermöglicht es, gegebenenfalls unter Verwendung einer Mehrzahl von untereinander gleichen Hülsen-Elementen eine optimale Längenanpassung des Prothesenschaftes zu realisieren, wobei bereits vor der Operation die einzelnen Elemente zum Ausprobieren der optimalen Konfiguration zusammensteckbar sind und die Elemente bei der Operation dann in übersichtlicher Weise vormontiert auf dem üblicherweise verwendeten Sieb liegen können.A shaft of this type is known from DE 43 20 086 A1. A shaft of this type makes it possible to achieve an optimal length adjustment of the prosthetic shaft, if necessary using a plurality of identical sleeve elements, whereby the individual elements can be put together before the operation to try out the optimal configuration and the elements can then be pre-assembled in a clear manner on the sieve that is usually used during the operation.

Bei implantiertem Prothesenschaft hat der Operateur die Möglichkeit, die Antetorsion des Prothesenmoduls nachträglich festzulegen. Letztlich istWhen a prosthetic stem is implanted, the surgeon has the option of subsequently determining the antetorsion of the prosthetic module. Ultimately,

eine einfache Zerlegung möglich, da keine selbsthemmenden Klemmverbindungen mit Hilfe besonderer Werkzeuge gelöst werden müssen. Dementsprechend ist auch ein Wechsel des Prothesennagels problemlos möglich.easy disassembly is possible, as no self-locking clamp connections have to be loosened using special tools. Accordingly, changing the prosthetic nail is also possible without any problems.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Schaft der eingangs genannten Art so weiterzubilden, daß in bestimmten Anwendungsfällen eine noch weiter erleichterte Implantation realisierbar ist.Based on this, the invention is based on the object of developing a shaft of the type mentioned at the beginning in such a way that in certain applications an even easier implantation can be achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Verankerungsabschnitt eine Längsbohrung aufweist, die sich über den Innengewindeabschnitt hinaus bis zum distalen Ende des Verankerungsabschnitts diesen vollständig durchsetzend erstreckt.This object is achieved according to the invention in that the anchoring section has a longitudinal bore which extends beyond the internal thread section to the distal end of the anchoring section completely penetrating the latter.

Die erfindungsgemäße Ausgestaltung ermöglicht es, den kanülierten Nagel über einen Führungsspieß einzuschlagen, d.h. der Nagel wird praktisch auf den Führungsspieß mit seiner durchgehenden Bohrung aufgefädelt und so eingesetzt, was eine zentrale Lage im körperfernen Femurschaft garantiert und die Nagelung körperferner Femurfrakturen erleichtert. Die Längenbestimmung kann über eine Skalierung des Prothesen-Einschlag- bzw. Ausschlaginstrumentes erfolgen. In an sich bekannter Weise kann der Antetorsionswinkel stufenlos eingestellt werden.The design according to the invention makes it possible to drive in the cannulated nail using a guide rod, i.e. the nail is practically threaded onto the guide rod with its through-hole and inserted in this way, which guarantees a central position in the distal femoral shaft and facilitates the nailing of distal femoral fractures. The length can be determined using a scale on the prosthesis driving or removing instrument. The antetorsion angle can be continuously adjusted in a conventional manner.

Dieser Nagel ist die Basis für die aufzusetzenden Module zur Behandlung von Verriegelungspflichtigen Femurschaftfrakturen, Trochanterfrakturen und für sub- und periprothetische Frakturen, traumatisch und pathologisch sowie intraoperativ entstanden bei Wechseloperationen, bei Tumoren im femoralen Hüftgelenksbereich sowie als Revisionsprothese bei dystrophem Knochen bzw. nach mehreren Wechseloperationen.This nail is the basis for the modules to be attached for the treatment of femoral shaft fractures requiring locking, trochanter fractures and for sub- and periprosthetic fractures, traumatic and pathological as well as intraoperatively occurring during revision operations, for tumors in the femoral hip joint area and as a revision prosthesis for dystrophic bone or after several revision operations.

Durch die erfindungsgemäße Ausgestaltung in Verbindung mit den gattungsgemäß bekannten Merkmalen wird eine frühzeitig belastungsstabile Femurfrakturbehandlung selbst bei prothetisch versorgter Hüfte und eine hohe Belastungsstabilität im Fall von Tumoren erreicht. Eine Zementierung ist wegen des sternförmigen Profils des Nagels und der knochenassoziativen Eigenschaft des Materiales (Titan) entbehrlich.The design according to the invention in conjunction with the generically known features enables early, load-stable treatment of femoral fractures even in the case of prosthetic hips and high load stability in the case of tumors. Cementing is not necessary due to the star-shaped profile of the nail and the bone-associative properties of the material (titanium).

Es ist ferner vorgesehen, daß der Nagel im distalen Bereich Bohrungen exakt senkrecht zur Längsachse aufweist zur Einbringung von Verriegelungsschrauben bzw. Verriegelungsbolzen. Durch eine solche Verankerung wird eine Stabilisierung gegen Belastungen sowohl in axialer Richtung als auch gegen Torsionsbeanspruchungen erreicht. Gerade in Kombination mit einer solchen stabilen Verankerung ist es von großem Vorteil, den Antetorsionswinkel nachträglich noch einstellen zu können.It is also intended that the nail in the distal area has holes exactly perpendicular to the longitudinal axis for the insertion of locking screws or locking bolts. This type of anchoring provides stabilization against loads in both the axial direction and against torsional stress. Especially in combination with such a stable anchoring, it is a great advantage to be able to subsequently adjust the antetorsion angle.

Ein derartiger Schaft kann mit Vorteil eingesetzt werden für sub- und periprothetische Frakturen, traumatisch und pathologisch sowie intraoperativ bei Wechseloperationen, bei Tumoren im femoralen Hüftgelenksbereich sowie als Revisionsprothese bei dystrophem Knochen bzw. nach mehreren Wechseloperationen.Such a stem can be used advantageously for sub- and periprosthetic fractures, traumatic and pathological as well as intraoperatively during revision operations, for tumors in the femoral hip joint area and as a revision prosthesis in dystrophic bone or after several revision operations.

Durch die erfindungsgemäße Ausgestaltung in Verbindung mit den gattungsgemäß bekannten Merkmalen wird eine frühzeitig belastungsstabile Femurfrakturbehandlung der prothetisch versorgten Hüfte und eine hohe Belastungsstabilität der Hüfte im Fall von Tumoren erreicht. Eine Zementierung ist entbehrlich und damit einhergehend wird eine kurze Operationszeit erreicht.The design according to the invention in conjunction with the generically known features enables early, load-stable treatment of femoral fractures of the prosthetically treated hip and high load stability of the hip in the case of tumors. Cementing is not necessary and this results in a short operation time.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß der Verankerungsabschnitt im distalen Endbereich wenigstens eine Bohrung etwa senkrecht zur Längsachse aufweist zur Einbringung von Verriegelungsschrauben bzw. Vernegelungsnägeln. Durch eine solche Verankerung wird eine Stabilisierung gegen Belastungen sowohl in axialer Richtung als auch gegen Torsionsbeanspruchungen erreicht. Gerade in Kombination mit einer solchen stabilen Verankerung ist es von großem Vorteil, den Antetorsionswinkel nachträglich noch einstellen zu können.In a further embodiment of the invention, it is provided that the anchoring section in the distal end area has at least one hole approximately perpendicular to the longitudinal axis for the insertion of locking screws or nails. Such an anchoring achieves stabilization against loads in both the axial direction and against torsional stresses. Especially in combination with such a stable anchoring, it is a great advantage to be able to subsequently adjust the antetorsion angle.

Mit besonderem Vorteil sind die Verriegelungsschrauben kanuliert, so daß deren Einbringung über einen Führungsspieß möglich ist.It is particularly advantageous that the locking screws are cannulated so that they can be inserted via a guide wire.

Die Erfindung stellt also ein universelles Nagel- bzw. Schaftsystem dar, mit dem alle Frakturen des Femurschaftes zu behandeln sind und stellt eine Alternative zu den sogenannten Femur-Verriegelungsnägeln dar. Wei-The invention therefore represents a universal nail or shaft system, with which all fractures of the femoral shaft can be treated and represents an alternative to the so-called femoral locking nails.

terhin können alle Frakturen im Trochanterbereich des Femur therapiert werden. Letztlich können noch alle Frakturen behandelt werden, die sich bei implantierter Hüftprothese (subprothetische und periprothetische Frakturen) ereignen.Furthermore, all fractures in the trochanteric region of the femur can be treated. Finally, all fractures that occur during implantation of a hip prosthesis (subprosthetic and periprosthetic fractures) can be treated.

Dementsprechend umfaßt dieses System also den eigentlichen Nagel oder Schaft sowie auf diesen aufsteckbare, unterschiedliche Module für die verschiedenen Anwendungsbereiche, also Prothesenmodule, Trochantermodule und Diaphysenmodule.Accordingly, this system includes the actual nail or shaft as well as different modules that can be attached to it for the various areas of application, i.e. prosthesis modules, trochanter modules and diaphyseal modules.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausfuhrungsbeispiels näher beschrieben. Dabei zeigenThe invention is described in more detail below using a preferred embodiment.

Fig. 5 eine Ansicht einer Verriegelungsschraube.Fig. 5 a view of a locking screw.

Ein in der Zeichnung dargestellter Prothesenschaft 1 umfaßt einen Verankerungsabschnitt 2, einen abgekröpften Gelenkugelabschnitt 3 sowie einen Verlängerungsabschnitt 4, der im Ausführungsbeispiel aus einem Hülsen-Element 5 gebildet ist.A prosthetic shaft 1 shown in the drawing comprises an anchoring section 2, a bent joint ball section 3 and an extension section 4, which in the embodiment is formed from a sleeve element 5.

Die Verbindung der einzelnen Elemente 5 der modular aufgebauten Prothese erfolgt über Konusabschnitte, d.h. über Konusansätze 6 und Konusausnehmungen 7.The individual elements 5 of the modular prosthesis are connected via cone sections, i.e. via cone attachments 6 and cone recesses 7.

Der Gelenkkugelabschm'tt 3 und der Verlängerungsabschnitt 4 weisen eine Längsbohrung 8 mit einer Längsachse 9 auf.The joint ball section 3 and the extension section 4 have a longitudinal bore 8 with a longitudinal axis 9.

Diese Längsbohrung 8 setzt sich fort in dem Verankerungsabschnitt 2 als zentrale, durchgehende Bohrung 10, welche im distalen Endbereich als Gewindebohrung 11 ausgebildet ist. Dementsprechend kann, wie an sich aus DE 43 20 086 Al bekannt, durch eine Sicherungsschraube 12, die in den Gewindeabschnitt 11 eingreift, eine Verspannung des Systems realisiert werden.This longitudinal bore 8 continues in the anchoring section 2 as a central, continuous bore 10, which is designed as a threaded bore 11 in the distal end area. Accordingly, as is known from DE 43 20 086 A1, the system can be braced using a locking screw 12 that engages in the threaded section 11.

Die Längsbohrung 8 und die diese fortsetzende Längsbohrung 10 des Verankerungsabschnitts 2 ermöglichen es, den Schaft 1 über einen Führungsspieß zu implantieren.The longitudinal bore 8 and the longitudinal bore 10 of the anchoring section 2 that continues therefrom make it possible to implant the shaft 1 via a guide wire.

Die Fig. 3 und 4 zeigen die sternförmige Querschnittskonfiguration des Verankerungsabschnitts 2.Figures 3 and 4 show the star-shaped cross-sectional configuration of the anchoring section 2.

Im distalen Endbereich 13 des Verankerungsabschnitts 2 sind zwei Bohrungen 14 vorgesehen, welche den Verankerungsabschnitt 2 senkrecht zur Längsachse 9 durchsetzen und zur Einbringung von Verriegelungsschrauben 15, von denen eine in Fig. 5 dargestellt ist, verwendet werden.In the distal end region 13 of the anchoring section 2, two bores 14 are provided, which penetrate the anchoring section 2 perpendicular to the longitudinal axis 9 and are used to insert locking screws 15, one of which is shown in Fig. 5.

Eine Verriegelungsschraube 15 umfaßt einen Kopf 16, einen glatten Mittelabschnitt 17 und einen Gewindeabschnitt 18.A locking screw 15 comprises a head 16, a smooth central portion 17 and a threaded portion 18.

Der vorstehend beschriebene Prothesenschaft bzw. -nagel 1 stellt praktisch den Basisnagel dar und dient, wie schon erwähnt, für den Indikationsbereich peri- und subprothetische Frakturen. Er kann vorzugsweise in Stärken von 11, 12 und 13 mm bei einer Länge von 310 mm ausgeführt werden.The prosthetic shaft or nail 1 described above practically represents the base nail and, as already mentioned, is used for the indication area of peri- and subprosthetic fractures. It can preferably be made in thicknesses of 11, 12 and 13 mm with a length of 310 mm.

Ein zweites, in der Zeichnung nicht dargestelltes Modul ist das Trochanter-Modul, welches gebildet wird durch eine konische Hülse von mindestens 4 cm Länge. Diese Hülse wird in verschiedenen Größen, beispielsweise in 1,5 cm-Schritten, vorrätig gehalten, wobei die Hülsen eine aufsteigende Bohrung mit unterschiedlichen Winkeln (z.B. 120° und 130°) aufweisen, durch die ein Nagel mit einem Dreizacksternprofil geführt wird, der im Schenkelhals plaziert wird. Ein derartiger Nagel kann eine Modifikation des vorbekannten Drei-Lamellen-Nagels darstellen und eineA second module, not shown in the drawing, is the trochanter module, which is formed by a conical sleeve of at least 4 cm in length. This sleeve is kept in stock in different sizes, for example in 1.5 cm increments, whereby the sleeves have an ascending bore with different angles (e.g. 120° and 130°) through which a nail with a trident star profile is guided, which is placed in the femoral neck. Such a nail can represent a modification of the previously known three-lamellar nail and a

zentrale Bohrung umfassen, die es ermöglicht, diesen Nagel über einen Kirschner-Draht als Führungsdraht in den Schenkelhals einzuschlagen.central hole that allows this nail to be driven into the femoral neck using a Kirschner wire as a guide wire.

Die Indikation für diese Kombination sind sub- und pertrochantäre Frakturen. Er stellt damit eine Alternative zu Nägeln wie Gamma-Nagel, Classic Nail, Y-Nagel oder dynamische Hüftschraube und Pohl'scher Laschenschraube dar.The indication for this combination is sub- and pertrochanteric fractures. It therefore represents an alternative to nails such as the Gamma nail, Classic Nail, Y-nail or dynamic hip screw and Pohl's tab screw.

Schließlich ist noch ein Verriegelungsmodul vorgesehen, welches ebenfalls aus einer Hülse besteht, beispielsweise in vier Längen mit 1,5 cm-Schritten, wobei diese Hülse zylindrisch ausgestaltet ist und nicht dicker zu sein braucht als der Nagel bzw. Schaft.Finally, a locking module is provided, which also consists of a sleeve, for example in four lengths with 1.5 cm increments, whereby this sleeve is cylindrical and does not need to be thicker than the nail or shaft.

Anwendungsbereiche für dieses Modul sind alle Formen von Femurfrakturen, die bisher mit dem herkömmlichen Verriegelungsnagel versorgt wurden. Darüber hinaus stellt dieses Modul eine Alternative zu neueren Versionen dar, bei welchen die Markhöhle nicht mehr durch Aufbohrung aufgeweitet werden muß.Areas of application for this module include all types of femoral fractures that have previously been treated with the conventional locking nail. In addition, this module represents an alternative to newer versions in which the medullary cavity no longer needs to be widened by drilling.

Dieses Modul weist ebenfalls eine schräge Bohrung auf, welche jedoch wesentlich dünner ist als bei anderen Modulen und ein Gewinde aufweisen kann zum Durchdrehen eines schrägen Verriegelungsbolzens.This module also has an angled hole, but it is much thinner than other modules and can have a thread for turning an angled locking bolt.
