Abstract

According to the invention, the geometrical data of the bone dimensions are to be recorded - assisted by a computer - from radiographs and/or computed tomographs, and the requisite moulds for metallic or other joint endoprostheses are to be produced by numerically controlled production facilities. Osteosynthesis plates and other bone substituting prostheses can be made directly or re-worked by this method.

thesematerial oder anderem Knochenersatz nach den Knochendi -mensionen des Patienten.thesis material or other bone substitute according to the bone dimensions of the patient.

Der Ersatz von Hüft-und Kniegelenken hat in- den letzten Dezennien eine explosionsartige Entwicklung genommen Trotzdem ist der Kompromiß gegenüber dem natürlichen Gelenk noch erheblich.The replacement of hip and knee joints has taken place in the last few decades Nevertheless, the compromise is up against the natural joint still considerably.

Bei den mit sogen. Knochenzement am Knochen verankerten Prothesenschäften hat sich die Rate der septischen Implantatlocker -ungen stark vermindert. Dadurch wurde die relativ große Rate der infektfreien Tjockerungen recht augenfällig, die durch folgende Ursachen entstehen: der am geringsten tragfähige Partner des Verbundes Knochen - Knochenzement - Metall, nämlich der Hnochenzement, ist den auftretenden Last- und Spannungssp durch den hohen Unterschied der Elastizitätsmoduli beeinflußt) auf Dauer nicht gewachsen und zerrüttet. Hierdurch korim- es .s-z unphysiologisch hohen oder niedrigen Beanspruchungen des Knochens der mit Resorption darauf reagiert. Ebenso kann es auch zur k£-scr -tion durch Stoffwechselstörungen im Knochen kommen, die dadurch ausgelöst werden, daß der Knochenzement und Implantatschaft den Markraum verstopfen. In diesem Zusammenhang muß angefügt erden, daß die Ernährung des Knochens größtenteils durch den Markraiiir erfolgt. Diese Probleme führten zur Entwicklung der zementfreien Prothesen mit Tragrippen oder einer Oberflächenstruktur, in die der Knochen hineinwachsen soll. Im Zuge dieser Entwicklung id dem Operateur jetzt zementfreie Prothesen verschiedeiier Formen und Dimensionen anhand gegeben. Allerdings muß der Markraum je -weils durch umfangreiche Knochenresektionen dem Implantat a^^e -paßt werden. Oftmals gelingt dies nur in einer Ebene, sodaC Lo nen mit unphysiologischer Beanspruchung des Knochens infolge @@ spitzen entstehen, in denen der Knochen dann resorbiert. Die le erdung des Prothesenschaftes ist die Folge.With the so-called Prosthetic shafts anchored to the bone by bone cement the rate of septic implant loosening has decreased significantly. Through this the relatively high rate of infection-free jokers became quite obvious caused by the following causes: the least sustainable partner in the network Bone - bone cement - metal, namely the bone cement, is the occurring Load and tension sp influenced by the large difference in the moduli of elasticity) not grown in the long run and shattered. As a result, korim- es .s-z is unphysiological high or low stresses on the bone, which reacts to it with resorption. It can also lead to k £ -scr -tion due to metabolic disorders in the bones, which are triggered by the fact that the bone cement and implant shaft enter the medullary canal clog. In this connection it must be added that the nutrition of the bones largely done through the Markraiiir. These problems led to the development of cementless prostheses with support ribs or a surface structure into which the bone should grow into it. In the course of this development, the surgeon id now cement-free prostheses based on various shapes and dimensions. However the medullary canal must be attached to the implant a ^^ e -be adjusted. Often this only works on one level, so that it is unphysiological Stress on the bone as a result of @@ sharp points, in which the bone then absorbed. The result is that the prosthesis stem becomes empty.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile größtmöglichst zu vermeiden. Die Lösung dieser Aufgabe besteht in der dem Patienten individuell angepaßten Prothese.The invention is based on the task of addressing these disadvantages as much as possible to avoid. The solution to this task consists in the individual patient adapted prosthesis.

Diese Daten werden vom Computer mit deren der vohandenen oder vom Handel bereitgehaltenen Prothesen verglichen.As is known, the network of all geometries is computer-aided of the coordinate points (similar to the measurement of the earth in the required Density for the respective zone, augenorrer and saved. These data are from Computer with their existing or kept by the trade Prostheses compared.

Ist keine passende Prothese verfügbar, übernimmt eine numerisch gesteuerte rräs- oder Schleifmaschine die Daten und fertigt nach diesen ein modells nach dem eine Negativform aus Ton oder der£leicnen oder anderem Material hergestellt werden kann.

Taking into account the reject rate in production (material testing, Manufacturing tolerances), any number of molds can be made to measure for production the prosthesis, which is done in a known manner.

Eine Nachbearbeitung vorhandener Prothesen, zwecks Anpassung Knochendimensionen, ist nach dieser Methode ebenfalls möglich.Post-processing of existing prostheses for the purpose of adapting bone dimensions, is also possible using this method.
