Abstract
Description
Gegenstand der Erfindung sind eine PMMA-Paste (Polymethylmethacrylat-Paste), deren Verwendung und sie enthaltende pastenförmigen Einkomponenten-Knochenzemente oder Zweikomponenten-Knochenzemente.object of the invention are a PMMA paste (polymethyl methacrylate paste), their use and containing single-component pasty bone cements or bicomponent bone cements.
PMMA-Knochenzemente
sind seit Jahrzehnten bekannt und gehen auf die grundlegenden Arbeiten
von Sir Charnley zurück (
Grundlegende
mechanische Anforderungen an PMMA-Knochenzemente, wie 4-Biegefestigkeit, Biegemodul
und Druckfestigkeit, sind in der
Ein Nachteil der konventionellen PMMA-Knochenzemente für den Zementproduzenten besteht darin, dass sowohl die Pulverkomponente als auch Monomerkomponente jeweils doppelt steril verpackt hergestellt werden müssen. Das bedeutet, es sind mindestens vier sterile Packmittel für eine Knochenzementpackung notwendig.One Disadvantage of conventional PMMA bone cements for the Cement producers is that both the powder component as well as monomer component each produced double sterile packaged Need to become. That means there are at least four sterile ones Packaging for a bone cement package necessary.
Ein weiterer Nachteil der bisherigen PMMA-Knochenzemente für den medizinischen Anwender besteht darin, dass die flüssige Monomerkomponente mit der Pulverkomponente unmittelbar vor der Zementapplikation in einem Mischsystem oder in Tiegeln vermischt werden muss. Dabei können leicht Mischungsfehler auftreten, welche die Zementqualität negativ beeinflussen können. Nach der Vermischung der Monomerkomponente mit der Pulverkomponente muss je nach Zementtyp eine gewisse Zeit gewartet werden, bis der Zementteig klebfrei ist und appliziert werden kann. Danach hat der Anwender eine mehr oder weniger kurze Verarbeitungszeit zur Verfügung in der Totalendoprothesen positioniert werden können oder Knochenkavitäten wie bei der Kyphoplastie und Vertebroplastie aufgefüllt werden können. Während der Verarbeitungszeit verändert sich die Viskosität des Zementteigs infolge der zunehmenden Quellung der Polymerpartikel im Monomer und der fortschreitenden Polymerisation des Monomers. Die relativ kurze Verarbeitungszeit ist ein wesentlicher Nachteil der bisherigen Knochenzemente. Besonders nachteilig sind kurze Verarbeitungszeiten bei der Kyphoplastie und Vertebroplastie. Wünschenswert wäre ein Zement, insbesondere für die Vertebroplastie und Kyphoplastie, bei dem die Viskosität des Zementteigs während der Zementapplikation über einen Zeitraum von mehreren Minuten weitgehend konstant bleibt.One Another disadvantage of the previous PMMA bone cements for the medical user is that the liquid Monomer component with the powder component immediately before the cement application must be mixed in a mixing system or in crucibles. there Miscibility errors can easily occur which negatively affect the cement quality can influence. After mixing the monomer component with the powder component has a certain time depending on the type of cement Wait until the cement paste is tack-free and applied can. After that, the user has a more or less short processing time be positioned in the total endoprostheses or bone cavities as in kyphoplasty and Vertebroplasty can be filled up. While the processing time changes the viscosity of the cement paste as a result of the increasing swelling of the polymer particles in the monomer and the progressive polymerization of the monomer. The relatively short processing time is a significant disadvantage the previous bone cements. Particularly disadvantageous are short processing times in kyphoplasty and vertebroplasty. Desirable would be a cement, especially for vertebroplasty and kyphoplasty, where the viscosity of the cement paste during the cement application over a period of time remains largely constant for several minutes.
Die Aufgabe der Erfindung besteht deshalb darin, eine PMMA-Paste zu entwickeln, die als Ausgangsmaterial für die Herstellung von pastenförmigen PMMA-Knochenzementen eingesetzt werden kann, welche die Probleme der bekannten PMMA-Knochenzemente überwinden können.The The object of the invention is therefore to a PMMA paste develop as starting material for the production paste-type PMMA bone cements can be used, which overcome the problems of the known PMMA bone cements can.
Die Aufgabe der Erfindung wird durch eine PMMA-Paste nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Ansprüchen.The The object of the invention is achieved by a PMMA paste according to claim 1 solved. Advantageous embodiments will be apparent from the further claims.
Die erfindungsgemäße PMMA-Paste wird aus einem Gemisch aus

Überraschend wurde gefunden, dass Pasten mit einem Anteil an Methylmethacrylat von größer gleich 50 Gewichtsprozent autosteril sind. Das bedeutet, dass Methylmethacrylat bewirkt eine Abtötung von mikrobiellen Keimen in der PMMA-Paste. Entsprechend sind PMMA-Pasten bevorzugt, bei denen ein Gewichtsverhältnis von 10–50% Polymethylmethacrylat zu 50–90% Methylmethacrylat vorliegt.Surprised was found to be pastes containing a proportion of methyl methacrylate greater than or equal to 50% by weight autosteril are.

For this purpose, the PMMA paste with organic and / or inorganic fillers and with radical initiators and / or accelerators for the production mixed by one-component and two-component bone cements.
Vorzugsweise werden organische und anorganische Füllstoffe, die in Methylmethacrylat nicht quellen und eine Methylmethacrylat-Aufnahme von kleiner 25% haben, mit der PMMA-Paste vermischt.Preferably Be organic and inorganic fillers in methyl methacrylate not swelling and a methyl methacrylate uptake of less than 25% have mixed with the PMMA paste.
Insbesondere wird die erfindungsgemäße PMMA-Paste zur Herstellung eines Mittels zur Fixierung von Totalendoprothesen und Revisionsendoprothesen verwendet.Especially is the PMMA paste according to the invention for the preparation a means for fixing total endoprostheses and revision endoprostheses used.
Besonders vorteilhaft ist die Verwendung der erfindungsgemäßen PMMA-Paste zur Herstellung eines selbsthärtenden Füllmaterials für die Vertebroplastie, Kyphoplastie und die Femurhalsaugmentation.Especially advantageous is the use of the invention PMMA paste for the production of a self-hardening filling material for vertebroplasty, kyphoplasty and femoral neck augmentation.

B. möglich, mit einem Antibiotikum enthaltenden aus der erfindungsgemäßen PMMA-Paste hergestellten PMMA-Knochenzement kugelförmige oder bohnenförmige Implantate zu formen, die als lokale Wirkstofffreisetzungssysteme eingesetzt werden können.The PMMA paste according to the invention can also be used for the production used by local drug release systems. So is it z. B. possible, containing an antibiotic from the PMMA bone cement prepared according to the invention PMMA paste spherical or bean-shaped implants forms used as local drug release systems can.
