Abstract

Method for preserving human bone material, esp. bone marrow (spongiosa) comprises sterilising it with gamma rays. The treatment can be preceded by a non-sterilising pre-cleaning with ultrasound. USE/ADVANTAGE - The treated material (1) has no blood gp. incompatibilities (it no longer has any blood gp. specific properties); (2) retains its ability to stimulate growth of other bone; (3) has shelf life of 5 years; (4) ensures adequate supply of bone material for surgical use at all times; (5) does not require any complicated processing and (6) can be supplied in a variety of shapes (e.g. discs, cubes, pegs or powder).

Description

Die Erfindung betrifft ein Verfahren zur Konservierung menschlicher Knochensubstanz, insbesondere Knochenkernmasse (Spongiosa).The invention relates to a method for preservation human bone, in particular Bone core mass (cancellous bone).

Knochenkernmasse wird in der modernen Chirurgie bei zahlreichen Operationen benötigt. Als Knochenkernmasse wird Material verwandt, welches bei Operationen, bei Unfallopfern od. dgl. anfällt. Vor seiner Weiterverwendung sind zahlreiche histologische, laborchemische und weitere Untersuchungen an der Knochensubstanz notwendig. Erst wenn alle notwendigen Befunde in Ordnung sind, darf das Material einem anderen Patienten implantiert werden, z. B. zum Auffüllen von Knochendefekten. Da die Kriterien für nicht zu beanstandende Befunde durch die starke Zunahme der Infektionsmöglichkeiten, z. B. Aids, sehr streng gezogen worden sind, ist auch die Ausschußmasse der nicht verwendbaren Knochenkernmasse sehr gewachsen.Bone core mass is used in modern surgery numerous operations needed. As a bone core mass material is used which is used in operations, in Accident victims or the like. Before using it again are numerous histological, laboratory chemistry and others Bone examinations necessary. Only when all necessary findings are in order, the material may be implanted in another patient, e.g. B. to Filling bone defects. Because the criteria for not Findings objectionable due to the sharp increase in Infection options, e.g. B. AIDS, very strict the committee mass is also not usable bone core mass very grown.

Bei einem bekannten Verfahren wird die menschliche Knochenkernmasse nach einer mechanischen Vorbehandlung, bei -30°C im Gefrierschrank gelagert bzw. konserviert. Hierdurch erfolgt jedoch keine Sterilisation, so daß die spätere Verwendung der Knochenkernmasse nach wie vor mit großen Risiken verbunden ist. Diese Risiken sind :In a known method, the human Bone core mass after mechanical pretreatment,  stored or preserved at -30 ° C in the freezer. However, this does not result in sterilization, so that the later use of the bone core mass still with great risks. These risks are:

  • - extreme Infektionsgefahr von z. B. Aids,
    - große Ausschußmasse bei Einhaltung der empfohlenen Blutbefunde,
    - Blutgruppenunverträglichkeit ist gegeben,
    - Beachtung desRhesusfaktors. Hier besteht eine Gefahr für junge Frauen bei einer Schwangerschaft,
    - aufwendige Aufarbeitung der Knochensubstanz,
    - sterile Verpackung ist notwendig,
    - sterile Verarbeitung ist notwendig,
    - die Haltbarkeit beträgt nur ein Jahr,
    - nicht immer ist Knochenkernmasse in ausreichenden Mengen vorhanden,
    - nicht immer ist Knochenkernmasse in ausreichenden Formen vorhanden und
    - nicht immer ist Knochenkernmasse in ausreichenden Mengen in der benötigten Blutgruppe vorhanden.
    - extreme risk of infection from z. B. AIDS,
    - large reject mass if the recommended blood results are observed,
    - blood group intolerance is given,
    - Consideration of the rheus factor. There is a danger here for young women during pregnancy,
    - elaborate processing of the bone substance,
    - sterile packaging is necessary,
    - sterile processing is necessary,
    - the shelf life is only one year,
    - there is not always sufficient amount of bone core,
    - Bone core mass is not always available in sufficient forms and
    - Bone core mass is not always available in sufficient quantities in the required blood group.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zu schaffen, das eine Sterilisation der Knochenkernmasse ermöglicht.The invention is therefore based on the object To create procedures that sterilize the Bone core mass allows.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß zur Sterilisation der Knochenkernmasse diese mit
γ- Strahlen bestrahlt wird.
This object is achieved according to the invention in that for the sterilization of the bone core mass
γ rays is irradiated.

In Ausgestaltung der Erfindung erfolgt eine unsterile Vorreinigung der Knochenkernmasse mit Ultraschall. An embodiment of the invention is non-sterile Pre-cleaning of the bone core mass with ultrasound.  

Nachfolgend wird das Verfahren im einzelnen beschrieben. Die Knochenkernmasse, z. B. gefrorene ganze Hüftköpfe oder schon teilweise präparierte Knochenstücke, werden von den Krankenhäusern übernommen und in Tiefkühltruhen gelagert. Hierbei kann die Knochenkernmasse noch unsteril sein. Anschließend wird die Knochenkernmasse in ein Sieb gegeben und in einem Ultraschallbad ohne Reinigungsmittel gereinigt. Danach werden die Knochenstücke sortiert, z. B. ganze Hüftköpfe, oder in verschiedenen Größen z. B. mit Meißel, Hammer oder Säge, zu Scheiben, Keilen od. dgl. zurechtgesägt und nochmals im Ultraschallbad gereinigt. Es ist aber auch möglich, aus den Knochen die Knochenkernmasse (Spongiosa) mit speziellen Instrumenten herauszuarbeiten und diese Knochenkernmasse beispielsweise in Würfelform zu pressen. Danach erfolgt die Verpackung in Behälter, z. B. Röhrchen. Die so vorbereitete und verpackte Knochensubstanz wird mit γ-Strahlen sterilisiert.The method is described in detail below. The bone core mass, e.g. B. frozen whole femoral heads or Pieces of bone that have already been partially prepared are Hospitals and stored in freezers. The bone core mass can still be non-sterile. The bone core mass is then placed in a sieve and cleaned in an ultrasonic bath without detergent. Then the bone pieces are sorted, e.g. B. whole Femoral heads, or in different sizes e.g. B. with chisel, Hammer or saw, sawn into disks, wedges or the like and cleaned again in an ultrasonic bath. It is also possible to make bone mass (cancellous bone) from the bones to work out with special instruments and these To press bone core mass, for example, in the form of a cube. The packaging is then carried out in containers, e.g. B. tubes. The bone substance prepared and packaged in this way is included γ-rays sterilized.

Mit γ-Strahlen sterilisierte Knochensubstanz hat mehrere sehr große Vorteile:Bone substance sterilized with γ rays has several very big advantages:

  • 1. Es ist keine Blutgruppenunverträglichkeit mehr vorhanden, da nach der Sterilisation mit γ-Strahlen keine blutgruppenspezifischen Eigenschaften mehr vorhanden sind,1. There is no longer any blood type intolerance, there is none after sterilization with γ-rays blood group-specific properties are more present,
  • 2. die Proliferationsfähigkeit, d. h. die Fähigkeit, einen fremden Knochen zum Wachstum anzuregen, ist weiter vorhanden,2. the ability to proliferate, d. H. the ability to Encouraging foreign bones to grow continues available,
  • 3. die Haltbarkeit beträgt fünf Jahre,3. the shelf life is five years,
  • 4. die saubere Verpackung, z. B. in einem Röhrchen, ist für das OP-Personal sehr praktisch,4. the clean packaging, e.g. B. in a tube is for the operating room staff very practical,
  • 5. es ist jederzeit ausreichend Knochenkernmasse vorhanden,5. there is sufficient bone core mass at all times,
  • 6. es ist keine aufwendige Aufarbeitung von Hüftgelenkteilen, z. B. des Hüftgelenkkopfes, notwendig und6. it is not a complex refurbishment of hip joint parts, e.g. B. the femoral head, necessary and
  • 7. individuelle Knochenformen, z. B. Knochen-Scheiben, -Würfel, -Keile oder -Mehl, können angeboten werden.7. individual bone shapes, e.g. B. bone slices, - Cubes, wedges or flour can be offered.

Einige der vorstehenden Vorteile, beispielsweise keine Blutgruppenunverträglichkeit mehr, kombiniert mit der weiter bestehenden Proliferationsfähigkeit, sind sehr groß und waren in jeder Weise unvorhersehrbar.Some of the advantages above, for example none Blood type intolerance more, combined with the continued proliferation ability are very large and were unpredictable in every way.
