Ein besonderer Vorteil fur den Ersatz von Glied- maßen ist die verbandlose Dauerbefestigung im Röhrenknochen. Der Röhrenknochen wird zur Aufnahme der Prothesenverankerung entsprechend präpariert. In den Röhrenknochen wird an sich an den Innenwänden des Röhrenknochens mit einer selbstpolymerisierenden Polymerisatmasse, homogen ausgepreßt bzw. ausgespritzt, dem zur Selbsthärtung Schwefel oder Formaldehyd, sowie auch ein Dauerdesinfektionsmittel zur Autosterilhaltung der eingepreßten Polymerisatmasse beigefügt wird. Chlorthymol-Chlorxylenol hat sich bei I °/o Zusatz bestens bewährt. Zur Vermeidung von Infektionen des Knochenmarkes und auch um Reibungsdruck zu verhindern, wird vor Einführung eines spreizenden Drahthaltegerüstes aus nicht korrodierendem Zvlaterial, z. B. nicht rostender Stahl, erst flüssige Polymerisaffolie eingeträufelt, um nach Eintrocknung dieser Flüssigkeit eine fest anschließende, autosterile Polymerisathaut auf das Knochenmark in der inneren Knochenröhre zu bilden. Durch diesen Verschluß und die danach folgende Anpressung oder Anspritzung des Röhrenknochens zur Befestigung der Haltevorrichtung, ist eine Reinfektion ausgeschlossen. Das Fleisch des Amputationsstumpfes kann dann dicht den Knochenrand überwachsen, so daß auch dadurch eine Gefahr der Infektion vermieden wird.A particular advantage for the replacement of limb measured is the non-bonded permanent fixation in long bones. The long bone becomes The prosthesis anchorage is appropriately prepared. In the long bones is attached to the inner walls of the long bone with a self-polymerizing Polymer mass, pressed or injected homogeneously, with sulfur for self-hardening or formaldehyde, as well as a permanent disinfectant for keeping the car sterile is added to the pressed-in polymer composition. Chlorothymol-Chlorxylenol has proven itself Tried and tested with I ° / o addition. To prevent bone marrow infections and also to prevent frictional pressure, a spreading wire support frame is introduced before the introduction made of non-corrosive Zvlaterial, z. B. stainless steel, only liquid Polymerisaffolie instilled to form a solid after this liquid has dried Subsequent, autosterile polymer skin on the bone marrow in the inner bone tube to build. Through this closure and the subsequent pressing or injection of the long bone for fastening the holding device, reinfection is excluded. The flesh of the amputation stump can then tightly overgrow the edge of the bone, so that this also avoids the risk of infection.

Sollte es jedoch aus irgendeinem Grunde erforderlich sein, die Befestigungsvorrichtung aus dem Röhrenknochen zu entfernen, so geschieht dies leicht durch Erwärmung der Haltevorrichtung mittels hochfrequenter Ströme, indem die Metallhaltevorrichtung als Wärmeträger benutzt wird und die hasse in der Wärme erweicht und leicht herausgezogen werden kann. However, should it be necessary for any reason, the fastening device To remove from the long bones, this is easily done by heating the Holding device by means of high frequency currents by holding the metal holding device is used as a heat carrier and the hate is softened in the heat and easily pulled out can be.

Bei ausgeheiltem Amputationsstumpf, einerlei oh es sich um Arm oder Bein handelt, kann die Polymerisatprothese des Erfindungsgegenstandes auch dadurch störungsfrei und brauchbar ohne Verband befestigt werden, daß die Auslagerungsfläche der Prothesean dem Amputationsstumpf 5 bis toocmüber dem Stumpf als hermetisch abschol ießende Manschette ausgebildet ist, aus fleischfarbigem und fleischartig weichbleibendem Polymerisat besteht und mit einem Ventilabschlußrand versehen ist. Ein in diese Manschette eingearbeitetes Saugventil gestattet dem Prothesenträger die Prothese mittels einem feinen Schlauch fest- bzw. anzusaugen. Das Ventil schließt sich nach Durchführung des Ansaugprozesses und nach Entfernung des Saugverschlusses automatisch, so daß der Prothesenkörper des Erfindungsgegenstandes durch Vakuum so lange unlösbar verbunden ist. bis durch Anlüpfen der Vakuummanschette Luft in die le N fanschettensaugl)efestigung gelassen xvircl. With a healed amputation stump, regardless of whether it is arm or Leg acts, the polymer prosthesis of the subject matter of the invention can also thereby can be attached to the swap surface without disruption and usable without a bandage the prosthesis on the amputation stump 5 up to and including the stump is sealed off as hermetic iessende cuff is formed from flesh-colored and flesh-like soft material Polymer consists and is provided with a valve edge. One in this Cuff built-in suction valve allows the prosthesis wearer to use the prosthesis suck up or suck in using a fine hose. The valve closes afterwards Execution of the suction process and automatically after removal of the suction cap, so that the prosthesis body of the subject of the invention is inseparable for so long by vacuum connected is. until air enters the fan seal suction cup by attaching the vacuum cuff left xvircl.

Zwecks Vermeidung von Gewebeschadigung durch die Anlagerung der Prothese und Vakuurnl)efestigung kann die Manschette mit einem Salbenpolster versehen werden, dem nehen den Entzündung und Schneiß verhütenden Nfitteln auch ein nicht reizendes Desinfektionsmittel zugesetzt sein kann.In order to avoid tissue damage caused by the attachment of the prosthesis and vacuum fixation, the cuff can be provided with an ointment pad, In addition to the anti-inflammatory and sneeze-preventing agents, there is also a non-irritating one Disinfectants can be added.

Der Auslauf des Manschettenrandes wird zweckmäßig hautdünn gestaltet, so daß eine Abgrenzung zwischen Prothese und Körper fast nicht bemerkbar wird, so daß der Prothesenträger unauffällig Luft-, Sonnen- und Wasserbäder nehmen kann.The outlet of the cuff edge is expediently made skin-thin, so that a demarcation between prosthesis and body is almost imperceptible, like that that the prosthesis wearer can take air, sun and water baths inconspicuously.
