Abstract
Description
Die Erfindung betrifft ein Knochenimplantat, insbesondere eine Oberschenkelhalsprothese, mit einem länglichen Schaft mit einem oder mehreren, seitlich davon abstehenden Vorsprüngen zur Erwirkung einer kraftschlüssigen Verbindung zum anliegenden Knochen.The The invention relates to a bone implant, in particular a femoral neck prosthesis, with an elongated one Shaft with one or more, laterally protruding projections for Achievement of a frictional Connection to the adjacent bone.
Sehr häufig werden Hüftgelenksprothesen, insbesondere bei älteren Personen, die häufig an Osteoporose erkrankt sind und es öfter zu Oberschenkelhalsfrakturen kommt, implantiert. Auch Arthrosen des Hüftgelenks sind infolge übermäßigen Verschleisses oder genetisch bedingter Fehlstellungen des Hüftknochens eine häufige Indikation zur Implantation einer Hüftgelenksprothese bzw. einer Oberschenkelhalsprothese. Bei der Implantation wird der Oberschenkelhals mit dem Kugelgelenk vom Oberschenkelknochen abgetrennt. In den verbleibenden Oberschenkelknochen wird ein konisches Sackloch gefräst, dessen Kontur der Form des Schaftes der einzusetzenden Prothese entspricht. Diese ersetzt außerhalb des Oberschenkelknochens den Oberschenkelhals mit dem Kugelgelenk. Der Schaft des Implantats wird mit Knochenzement beschichtet, damit ein kraftschlüssiger Kontakt zwischen der Prothese und dem Knochen entsteht. Zur Unterstützung der Kraftschlüssigkeit und damit der Fixierung der Prothese am bzw. im Knochen ist der Schaft mit mehreren seitlich davon abstehenden, z. B. noppenartigen Vorsprüngen bestückt, so dass sich eine unregelmäßige, strukturierte Oberfläche ergibt, die einen besseren Halt bietet.Very often be hip joint prostheses, in particular in older Persons often suffer from osteoporosis and more often to femoral neck fractures comes, implanted. Also arthroses of the hip joint are due to excessive wear or genetically determined deformities of the hip bone is a common indication for implantation of a hip joint prosthesis or a femoral neck prosthesis. During implantation, the femoral neck becomes separated from the femur with the ball joint. In the remaining femurs a conical blind hole is milled, its contour of the shape of the shaft of the prosthesis to be used equivalent. This replaced outside of the femur the femoral neck with the ball joint. The shaft of the implant is coated with bone cement so that a force-fit Contact between the prosthesis and the bone arises. To support the force fit and thus the fixation of the prosthesis on or in the bone is the Shank with several laterally protruding, z. B. knob-like projections fitted, so that is an irregular, structured surface results, which offers a better grip.
Eine häufige Komplikation ist das Lösen der kraftschlüssigen Verbindung zwischen Prothesenschaft und Knochen, insbesondere im Falle einer Osteoporoseerkrankung. In einem solchen Fall wird bisher die Prothese operativ entweder erneut fixiert oder ausgetauscht.A frequent Complication is solving the non-positive Connection between prosthesis shaft and bone, especially in the Case of osteoporosis disease. In such a case will be so far the prosthesis either surgically fixed again or replaced.
Auch bei Knochenfrakturen kommen häufig Knochenimplantate zum Einsatz, die zwei gebrochene Knochen miteinander verbinden, das heißt, auch hier ist das Implantat im Knochen angeordnet und mit diesem verankert. Auch solche Implantate werden vornehmlich bei älteren Personen eingesetzt, wobei hier das Problem besteht, dass der Heilungsprozess relativ langsam vonstatten geht und infolgedessen eine konsequente Ruhigstellung erforderlich ist. Auch hier besteht das Problem, dass sich das Implantat vom Knochen lösen kann.Also bone fractures often involve bone implants used to connect two broken bones, this means, Again, the implant is located in the bone and with this anchored. Also, such implants are mainly used by the elderly The problem here is that the healing process is relative is slowly going on and consequently a consistent immobilization is required. Again, there is the problem that the implant detach from the bone can.
Der Erfindung liegt damit das Problem zugrunde, ein Knochenimplantat anzugeben, das ohne zusätzlichen Eingriff im Bedarfsfall erneut mit dem Knochen verankert werden kann.Of the The invention is thus based on the problem of a bone implant specify that without additional If necessary, engage the bone again can.
Zur Lösung dieses Problems ist bei einem Knochenimplantat der eingangs genannten Art erfindungsgemäß vorgesehen, dass der oder die Vorsprünge relativ zum Schaft verschiebbar und mit wenigstens einem im Schaft bewegbar aufgenommenen magnetischen Element, das über ein mit ihm wechselwirkendes externes Magnetfeld bewegbar ist, bewegungsgekoppelt ist.to solution This problem is with a bone implant of the aforementioned Art provided according to the invention, that or the projections displaceable relative to the shaft and with at least one in the shaft movably received magnetic element, which over a with it interacting external magnetic field is movable, motion coupled is.
Anders als bei allen bekannten Implantaten sind beim erfindungsgemäßen Knochenimplantat die seitlich hervorstehenden, üblicherweise noppenartigen Vorsprünge radial bewegbar, können also radial ausgefahren werden. Diese Bewegung wird über ein magnetisches Element gesteuert, das mit dem oder den radial verschiebbar gelagerten Vorsprüngen bewegungsgekoppelt ist. Dieses magnetische Element wirkt zum Verschieben der Vorsprünge mit einem externen Magnetfeld zusammen, das zum Bewegen des magnetischen Elements entsprechend variiert wird, so dass das magnetische Element der Feldbewegung bzw. Feldvariation folgt. Aus dieser Bewegung des magnetischen Elements resultiert infolge der Bewegungskopplung desselben zu den Vorsprüngen deren Bewegung.Different than in all known implants are in the bone implant according to the invention the laterally protruding, usually knob-like projections radially movable, can so be extended radially. This movement is via a magnetic Controlled element that with the or radially displaceably mounted projections is motion coupled. This magnetic element acts to move the projections with an external magnetic field that is used to move the magnetic Element is varied accordingly, so that the magnetic element the field movement or field variation follows. From this movement of the magnetic element results due to the motion coupling of the same to the tabs their movement.
Dies bedeutet, dass im Falle eines Lösens der kraftschlüssigen Verbindung beispielsweise des Oberschenkelhalsimplantats zum Knochen die Vorsprünge etwas weiter radial nach außen bewegt und wieder in bzw. an den Knochen geschoben werden, mithin also die Prothese wieder verankert wird. Bevorzugt sind dabei mehrere Vorsprünge vorgesehen, die einander gegenüber liegen, so dass sich die Prothese im Knochen wieder gut verspreizt.This means that in case of solving the frictional Connecting, for example, the femoral neck implant to the bone the projections slightly further radially outwards moved and pushed back into or on the bone, therefore So the prosthesis is anchored again. Preference is given to several projections provided, facing each other lie so that the prosthesis in the bone again spreads well.
Das erfindungsgemäße Knochenimplantat kann also allein durch Wechselwirkung des magnetischen Elements mit dem externen Magnetfeld erneut verankert werden, ein etwaiger wie bisher üblicher operativer Eingriff ist hier vorteilhaft nicht mehr vonnöten. Der Patient wird lediglich einem sich verändernden, bewegenden Magnetfeld ausgesetzt, über das die Bewegung der Vorsprünge gesteuert wird.The bone implant according to the invention can So only by interaction of the magnetic element with the be re-anchored external magnetic field, a possible as usual so far operational Intervention is advantageously no longer necessary here. The patient will only a changing, exposed to moving magnetic field, which controls the movement of the projections becomes.
Hinsichtlich der Bewegungskopplung des oder der Vorsprünge sind verschiedene Ausgestaltungen denkbar. Der oder die Vorsprünge können mit einem drehbar gelagerten Stellelement bewegungsgekoppelt sein, das seinerseits mit dem magnetischen Element bewegungsgekoppelt ist. Hier wird also durch eine Drehbewegung des Stellelements die Verschiebung der Vorsprünge realisiert, wobei diese Drehbewegung des Stellelements über das externe Magnetfeld in Verbindung mit dem magnetischen Element hervorgerufen wird. Alternativ ist es denkbar, ein linear verschiebbares Stellelement vorzusehen, mit dem die Vorsprünge gekoppelt sind, wobei auch dieses linear verschiebbare Stellelement mit dem magnetischen Element bewegungsgekoppelt ist und über das externe Magnetfeld linear bewegt werden kann.With regard to the movement coupling of the projection or projections, various embodiments are conceivable. The protrusion (s) may be motion coupled to a rotatably mounted actuator which in turn is motion coupled to the magnetic element. Here, therefore, the displacement of the projections is realized by a rotational movement of the actuating element, wherein this rotational movement of the actuating element is caused by the external magnetic field in connection with the magnetic element. Alternatively, it is conceivable vorzuse a linearly displaceable actuator hen, with which the projections are coupled, and this linearly displaceable actuator is coupled to the magnetic element and can be moved linearly via the external magnetic field.
Im Falle eines drehbar gelagerten Stellelements weist dieses zumindest im Bereich der Bewegungskopplung zu dem oder den Vorsprüngen einen unrunden Abschnitt auf. Der Durchmesser oder die Breite des drehbar gelagerten Stellelements variiert also, mithin werden also auch die Vorsprünge mehr oder weniger weit aus dem Schaft herausbewegt, je nachdem, wie die Stellung des unrunden Stellelements ist. Das unrunde Stell element ist dabei bevorzugt als längliche Stange ausgeführt, die querschnittlich zumindest abschnittsweise unrund ist, oder an der ein radial hervorstehender unrunder Ansatz vorgesehen ist, der beispielsweise als Scheibe oder dergleichen ausgeführt ist. „Unrund" bedeutet in diesem Fall beispielsweise einen ovalen Querschnitt oder einen Querschnitt mit einer im Wesentlichen „G"-Form. Denkbar ist aber jede Querschnittsform, die bei einer Rotation aufgrund der unrunden Form die erfindungsgemäße Vorsprungsbewegung erlaubt.in the Case of a rotatably mounted actuating element has this at least in the field of motion coupling to the one or more protrusions a non-circular Section on. The diameter or width of the rotatably mounted Stellelements thus varies, so therefore also the projections more or less far removed from the shaft, depending on how the position is the non-round actuator. The non-circular positioning element is included preferably as elongated Rod executed, the cross-section is at least partially out of round, or at the a radially projecting non-circular approach is provided, for example is designed as a disc or the like. "Out of round" in this case means, for example an oval cross section or a cross section with a substantially "G" shape but any cross-sectional shape that occurs during a rotation due to non-round shape the protrusion movement according to the invention allowed.
Ein linear verschiebbares Stellelement kann einen sich zumindest im Bereich der Bewegungskopplung zu dem oder den Vorsprüngen in seiner Form konisch erweiternden Abschnitt aufweisen. Hier ändert sich also der Durchmesser oder die Form des Stellelements im Wesentlichen kegelartig, so dass mithin auch in Abhängigkeit der Stellung des konischen Stellelements bezüglich der hinsichtlich der linearen Stellelementbewegung positionsfesten Vorsprünge diese mehr oder weniger weit herausgeschoben werden können. Dabei kann das Stellelement als längliche, zumindest abschnittsweise konische Stange ausgeführt sein, denkbar ist aber auch eine Ausführung als drehbare Gewindestange mit einer auf dieser laufenden konischen Stellmutter oder Stellhülse. Generell kann also jede Ausführung verwendet werden, bei der eine Linearbewegung des konischen Abschnitts zur erfindungsgemäßen Vorsprungsbewegung führt.One linearly displaceable actuator can be at least in Range of motion coupling to the one or more projections in have its shape conically widening section. Here changes that is, the diameter or the shape of the actuating element substantially conical, so that also depending on the position of the conical Control element with respect the positionally fixed with respect to the linear actuator movement projections these can be pushed out more or less. there can the actuator as elongated, at least partially conical rod be executed, but it is conceivable also an execution as a rotatable threaded rod with a conical running on this Adjusting nut or adjusting sleeve. In general, therefore, every execution used in which a linear movement of the conical section for the projection movement according to the invention leads.
Der oder die Vorsprünge sind bevorzugt mit einem Führungssteg in jeweils einer sich im Wesentlichen radial zur Schaftlängsachse erstreckenden Führungsbohrung geführt und über das Stegende bevorzugt direkt mit dem Stellelement bewegungsgekoppelt. Eine Bewegung des Stellelements resultiert also unmittelbar in einer Vorsprungsbewegung.Of the or the projections are preferred with a guide bar in each case one substantially radially to the shaft longitudinal axis extending guide bore guided and over the web end preferably directly coupled to the adjusting element motion. A movement of the actuating element thus results directly in one Projection moving.
Weiterhin kann vorgesehen sein, dass das ein drehbares Stellelement antreibende magnetische Element über das externe Magnetfeld drehbar und ein das linear verschiebbare Stellelement antreibende magnetische Element über das externe Magnetfeld linear verschiebbar gelagert ist. Die Bewegung des magnetischen Elements entspricht also der, die auch das Stellelement vornimmt. Ein drehbar gelagertes magnetisches Element wird folglich über ein sich drehendes externes Magnetfeld bewegt, während zur Bewegung des linear beweglichen magnetischen Elements das externe Magnetfeld linear verschoben wird. Das magnetische Element, das ein Permanentmagnet, vorzugsweise in Stabform, ist, folgt der Magnetfeldbewegung, die bei dieser Anwendung naturgemäß relativ langsam erfolgt.Farther can be provided that the driving a rotatable actuator magnetic element over the external magnetic field rotatable and the linearly displaceable Actuator driving magnetic element via the external magnetic field is mounted linearly displaceable. The movement of the magnetic Elements thus corresponds to that which also performs the actuator. A rotatably mounted magnetic element is thus connected to a rotating external magnetic field moves while moving to the linear movable magnetic element, the external magnetic field linear is moved. The magnetic element, which is a permanent magnet, preferably in rod form, follows the magnetic field movement that naturally relative to this application slowly.
Besonders zweckmäßig ist es, wenn dem magnetischen Element ein mit diesem gekoppeltes Untersetzungsgetriebe nachgeschaltet ist. Hierüber wird erreicht, dass eine Bewegung des magnetischen Elements, hervorgerufen durch das variierende externe Magnetfeld, in eine verglichen mit dem Bewegungsweg des magnetischen Elements wesentlich kürzere Bewegung des Stellelements umgesetzt wird, wodurch auch ein entsprechend hohes Drehmoment erzielt werden kann. Im Falle eines drehbar gelagerten magnetischen Elements, das über das Übersetzungsgetriebe mit einer beispielsweise querschnittlich ovalen Stange gekoppelt ist, wird das magnetische Element mehrfach um 360° gedreht, um die ovale Stange zwischen ihren beiden Extremstellungen bezüglich der Vorsprünge bzw. Stege zu verdrehen, wobei die Anzahl an Drehungen des Elements vom Untersetzungsverhältnis abhängt.Especially is appropriate it, when the magnetic element coupled to this reduction gear is downstream. About this is achieved that a movement of the magnetic element, caused through the varying external magnetic field, in comparison with the movement path of the magnetic element much shorter movement of the actuating element is implemented, whereby a correspondingly high torque can be achieved. In the case of a rotatably mounted magnetic element that over the transmission gear coupled with a cross-sectionally oval rod, for example is, the magnetic element is rotated several times 360 °, around the oval pole between its two extreme positions with respect to the projections or webs to twist, with the number of rotations of the element from the reduction ratio depends.
Die Ausgestaltung wird selbstverständlich so getroffen, dass eine Verstellposition fixiert bzw. arretiert ist und beibehalten wird, und eine unbeabsichtigte Rückbewegung ausgeschlossen ist. Es wird also vermieden, dass, sollte der Patient aus irgendwelchen Gründen einem externen Magnetfeld ausgesetzt sein, dieses versehentlich die ausgefahrenen Vorsprünge wieder zurückbewegt, weshalb beispielsweise entsprechend hohe Feldstärken zur Elementbewegung erforderlich sind. Vermieden wird auch, dass die gegen den Knochen gedrückten Vorsprünge nach Beendigung der Verstellbewegung das Stellele ment wieder etwas zurückschieben und so die feste kraftschlüssige Knochenanlage wieder etwas gelockert wird. Denkbar sind auch Arretiermechanismen, die beispielsweise über das externe Magnetfeld erst gelöst werden müssen, um eine erneute Verstellung vorzunehmen.The Design becomes obvious made such that an adjustment fixed or locked is and is maintained, and an inadvertent return movement is excluded. It is thus avoided that, should the patient For some reason be exposed to an external magnetic field, this accidentally the extended projections moved back again, which is why, for example, correspondingly high field strengths are required for element movement are. It is also avoided that the protrusions pressed against the bone after Completion of the adjustment movement, the Stellele ment push back a bit and so the solid frictional Bone system is loosened a bit again. Also conceivable locking mechanisms, the for example about the external magnetic field only solved Need to become, to make a new adjustment.
