Abstract
Description
Die Erfindung betrifft eine Augmentationskomponente zur Auffüllung von Knochendefekten mit einer metallischen, porösen Struktur.The The invention relates to an augmentation component for replenishing Bone defects with a metallic, porous structure.
Es
ist häufig
notwendig, knöcherne
Defekte durch eine sogenannte Augmentationskomponente zu überbrücken. Dabei
handelt es sich um Formkörper,
die in die knöchernen
Defekte eingesetzt werden und die entweder als Vollmaterial das
fehlende Knochenmaterial vollständig
ersetzen (
Andererseits
ist es auch bekannt, metallische poröse Festkörper zu verwenden, um Knochendefekte
zu überbrücken (
Es ist Aufgabe der Erfindung, eine gattungsgemäße Augmentationskomponente vorzuschlagen, die einerseits eine hohe Lasttragfähigkeit aufweist und die andererseits ein optimales Einwachsen von Knochenmaterial ermöglicht.It It is an object of the invention to provide a generic augmentation component to propose, on the one hand, a high load capacity On the other hand, an optimal ingrowth of bone material allows.
Diese Aufgabe wird bei einer Augmentationskomponente der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Augmentationskomponente aus einem dreidimensionalen Gerüst aus miteinander verbundenen Stegen aufgebaut ist, die untereinander verbundene kleine Hohlräume mit einer Größe in einem Bereich von 0,5 mm bis 6 mm einerseits, vorzugsweise von 0,5 mm bis 1 mm, und große Hohlräume mit einer Größe in einem Bereich von 6 mm bis 20 mm andererseits, vorzugsweise von 6 mm bis 10 mm, ausbilden.These Task is in an augmentation of the above-described Type according to the invention thereby solved, that the Augmentation component of a three-dimensional framework of each other connected webs is constructed, the interconnected small Cavities with one size in one Range of 0.5 mm to 6 mm on the one hand, preferably 0.5 mm to 1 mm, and large cavities with one size in one Range from 6 mm to 20 mm on the other hand, preferably from 6 mm to 10 mm, training.
Die kleinen Hohlräume gewährleisten eine ausreichende Festigkeit des Formkörpers, während die großen Hohlräume dazu dienen, in ihnen Knochenmaterial zu deponieren, beispielsweise autologes oder homologes Knochenmaterial. Ausgehend von diesen mit Knochenmaterial gefüllten großen Hohlräumen und von der Kontaktfläche zu den überbrückten Knochen kann das Knochenwachstum in die kleinen Hohlräume hinein erfolgen, so daß auch im Volumen des Augmentationskörpers eine größere Anzahl von Knochenwachstumszentren vorliegen, von denen aus das Knochenwachstum in die umgebenden kleinen Hohlräume erfolgen kann. Dies Kombination von kleinen Hohlräumen, die der Sicherstellung der Festigkeit dienen, und großen Hohlräumen, die als Vorratsvolumina Ausgangsstellen für das Knochenwachstum sind, führt zu einem deutlich schnelleren Durchwachsen des gesamten Gerüstes mit Knochenmaterial gegenüber Augmentationskörpern, bei denen das Einwachsen des Knochenmaterials ausschließlich von den Grenzflächen aus erfolgen kann.The small cavities guarantee a sufficient strength of the molding, while the large cavities serve to deposit bone material in them, for example, autologous or homologous bone material. Starting with these with bone material filled large cavities and from the contact surface to the bridged bones Bone growth can take place in the small cavities, so that in the Volume of the augmentation body A larger number of bone growth centers, from which bone growth into the surrounding small cavities can be done. This combination of small cavities that to ensure the firmness, and large cavities that as storage volumes are starting points for bone growth, leads to a significantly faster growing through the entire framework with Bone material opposite Augmentationskörpern, in which the ingrowth of the bone material exclusively by the interfaces can be done from.
Die Stege des Gerüstes können dabei eine Dicke in einem Bereich von 0,2 mm bis 2,5 mm aufweisen.The Webs of the scaffold can thereby have a thickness in a range of 0.2 mm to 2.5 mm.
Günstig ist es, wenn die relative Dichte der Augmentationskörper in einem Bereich von 0,05 bis 0,5 liegt. Durch den Aufbau des Gerüstes aus einzelnen Stegen ist der Volumenanteil des Gerüstmaterials gegenüber dem Volumenanteil der Hohlräume außerordentlich gering, und trotzdem läßt sich ein hohe Festigkeit erreichen. Es ist dadurch mit anderen Worten möglich, den größten Teil des Knochendefektes nach dem Einwachsen mit Knochenmaterial aufzufüllen und nicht mit dem Fremdmaterial der Augmentationskomponente.Cheap is it, if the relative density of the augmentation body in a range of 0.05 to 0.5. By building the framework of individual webs is the volume fraction of the framework material across from the volume fraction of the cavities extraordinarily small, and still can be achieve high strength. It is in other words possible, the biggest part fill the bone defect after ingrowth with bone material and not with the foreign material of the augmentation component.
Die Augmentationskomponente kann vorzugsweise aus Titan, einer Titanlegierung oder einer Cobaltlegierung bestehen.The Augmentation component may preferably be titanium, a titanium alloy or a cobalt alloy.
Es ist auch möglich, daß die Stege mit einer Beschichtung versehen sind, beispielsweise mit einer Calciumphosphatbeschichtung, die das Knochenwachstum und die Verbindung mit den Stegen fördert.It is possible, too, that the Webs are provided with a coating, for example with a Calcium phosphate coating, the bone growth and the compound promotes with the webs.
Die Größe der kleinen Hohlräume kann für das gesamte Volumen gleich sein, es ist aber auch möglich, daß die Größe der kleinen Hohlräume innerhalb der Augmentationskomponente variiert.The Size of the small cavities can for that Whole volume may be the same, but it is also possible that the size of the small cavities within the augmentation component varies.
Dabei kann sich die Größe der kleinen Hohlräume von einem Bereich der Augmentationskomponente zu einem anderen Bereich der Augmentationskomponente ändern, so daß auch die mechanische Festigkeit sich von Bereich zu Bereich ändert und optimal an den angrenzenden Knochen angepaßt werden kann.there can be the size of the small cavities from one area of the augmentation component to another area change the augmentation component, so that too the mechanical strength varies from area to area and can be optimally adapted to the adjacent bone.
Beispielsweise kann vorgesehen sein, daß sich die Größe der kleinen Hohlräume beim Übergang von einem Bereich zu einem anderen Bereich allmählich ändert, aber auch eine sprunghafte Änderung ist möglich.For example can be provided that the size of the small ones cavities at the transition gradually changing from one area to another area, but also a jumpy change is possible.
Es ist vorteilhaft, wenn ein einzelner großer Hohlraum oder eine Gruppe von mehreren großen Hohlräumen jeweils von kleinen Hohlräumen umgeben sind, so daß das Knochenwachstum ausgehend von den großen Hohlräumen nach allen Seiten in die kleinen Hohlräume hinein erfolgt. Dabei kann der Anteil der kleinen Hohlräume am Gesamtvolumen der Augmentationskomponente in einem Bereich von 50% bis 99%, vorzugsweise von 50% bis 90%, liegen, das heißt der größte Anteil des Volumens der Augmentationskomponente wird von kleinen Hohlräumen eingenommen, zwischen die großen Hohlräume eingelagert sind.It is advantageous if a single large cavity or a group of several large cavities are each surrounded by small cavities, so that the bone growth starting from the large cavities in all directions in the small cavities into it. In this case, the proportion of small cavities in the total volume of the augmentation component in a range of 50% to 99%, preferably from 50% to 90%, lie, that is, the largest proportion of the volume of the augmentation component is occupied by small cavities between the large cavities are stored.
Die großen Hohlräume können allseits von kleinen Hohlräumen umgeben sein, es ist aber auch möglich, daß die großen Hohlräume die Augmentationskomponente kanalförmig durchsetzen, in diesem Falle wird als Größe der Hohlräume deren Durchmesser angenommen. In diesem Falle kann das Knochenmaterial besonders einfach in die großen Hohlräume eingefüllt werden, außerdem kann durch diese großen Hohlräume von der Außenseite her besonders günstig verstärktes Knochenwachstum erfolgen.The huge cavities can on all sides of small cavities be surrounded, but it is also possible that the huge cavities enforce the augmentation channel-shaped, in this case is called the size of the cavities Diameter assumed. In this case, the bone material especially easy in the big ones cavities filled be, as well can through this great cavities from the outside especially favorable reinforced Bone growth done.
