Happel, Martin Wilhelm, Dr. Dr., 6072 Dreieich
Beschreibung:
Hüftpfannen- Implantate mit Gewinde zur zementlosen Verankerung, auch mit selbstschneidendem Gewinde, haben bislang häufig den
Nachteil, daß der Operateur bei solchen Hüftpfannen mit grobem Gewinde eine zu große Kraft aufwenden muß, sodaß auch Frakturen
im Becken auftreten können. Bei kleineren Gewindeprofilen, insbesondere bei solchen mit Dreiecks-oder Sägezahnform besteht die
Gefahr, daß eine ungenügende Verankerung durch die relativ glatt bearbeiteten Gewindeflächen verursacht wird.
Die Lockerung des Implantates ist die Folge. Der Erfindung liegt daher· die Aufgabe zugrunde, bei der Verankerung
einer zementlosen Huftgelenkpfarme mit Gewinde, diese Nachteile
zu vermeiden. Zu diesem Zweck vird zwar ein Gewinde mit dreieckigem Profil vorgesehen, das aber einen breiten Gewindegrund
hat, ähnlich, wie bei einer Spongiosaschraube. Der Gewindegrund wird durch Sandstrahlen, Plasmastrahlen o.a. mit einer Oberflächenstruktur
versehen. Beim Einschrauben setzt sich Blut in die Oberflächenstruktur und wirkt so als Gleitmittel, das die
Kraft zum Einschrauben wesentlich reduziert. Nach einiger Zeit wächst dann Knochen in die Oberflächenstruktur und bildet ein
solides Implantatlager.Ebenfalls zur Begrenzung der aufzubringenden
Kraft beim Einschrauben wird die Anzahl der Gewindegänge so beschränkt, daß diese nur etwa bis zur Hälfte der Höhe des Implantates
reichen. Desweiteren ist die äussere Form des Gewindes konisch, sodaß der Einschraubvorgang erleichtert wird. Das schalenartige
Huftgelenkpfannen- Implantat ist zur Aufnahme eines Lagereinsatzes für den mech. Hüftkopf vorgesehen. Der Lagereinsatz
wird in bekannter Weise mittels Federring und/ oder Preßsitz im vorgenannten Hüftpfannen- Implantat befestigt t Wenn nach
längerem Gebrauch infolge der Abnutzung ein neuer Lagereinsatz erforderlich ist, braucht nur dieser ausgetauscht zu werden,
während das Implaritatlager erhalten bleibt.
Die Erfindung wird in folgendem anhand von Ausführungsbeispielen näher erläutert, aus denen sich weitere wichtige Merkmale ergeben.

vergrößert den Gewinde- Querschnitt von Fig.1; Fig.4
schematisch teilweise den Querschnitt des Hüftpfannen- Implantates
mit Lagereinsatz und dessen Befestigung.
Fig.iund 3 stellen die spiralförmig um die Achse (1) der Hüftpfanne
angeordneten Gewindegänge (2) mit Gewindegrund (3) dar, dessen Oberfläche zur Verbesserung des Implantatlagers mit einer
Struktur versehen ist. Letztere kann nachträglich oder während des Verformungsvorganges aufgebracht werden. Die Öffnung mit dem
Durchmesser D (4) dient dazu, daß der Operateur nach dem Einsetzen der Hüftpfanne in das Becken die Möglichkeit hat, zwischen
der kugelartigen Oberfläche mit dem Radius R1 und dem Knochen Hohlräume zu erkennen und diese mit Knochenspänen auszufüllen.
Die äussere Form des Gewindes ist zur Erleichterung des Einschraub- \
Vorganges konisch (5) ausgebildet. Zum Einschrauben des Implantates '*
in den Knochen dienen mehrere konzentrisch angeordnete Nuten(6), in die ein Instrument mit entsprechenden Nocken eingreift. Zur
Sicherung des Lagereinsatzes gegen axiale Verschiebung ist eine Ringnut (7) vorgesehen, in die ein federnder Ring einrastet und
so den Lagereinsatz axial fixiert. Fig.2 zeigt die Aussparungen (8) für dasE. selbstschneidende Gewinde, in die Knochen einwächs'C
und so zur Verbesserung des Implantatlagers beiträgt. Fig.4 zeigt im Detail den Lagereinsatz (9) an dessen zylindrischem
Teil (10) eine Ringnut (7) für den Federring (11) angeordnet ist.
Zum Becken ist der Einsatz kugelförmig mit Radius R2. Der Lagereinsatz ist mit einem Kragen (12) versehen, der eine Beschädigung
der Oberfläche des mechanischen Hüftkopfes (13) an den Gewinde spitzen
beim Reponieren verhindert.
Claims (1)
