Abstract

Epithese mit Magnetankopplung dadurch gekennzeichnet, dass eine Epithese mit einem Magneten verbunden wird, der durch einen zweiten, implantierten Magneten am Kopf fixiert wird.

Description

  • Patienten mit angeborenen oder erworbenen Defekten insbesondere im Kopfbereich wünschen meist eine chirurgische oder prothetische Korrektur. Eine chirurgische Therapie kann aufwendig sein und führt nicht immer zu befriedigenden Resultaten. Daher ist bei vielen Patienten eine prothetische Versorgung mit Hilfe einer Epithese erforderlich.
  • Zur Befestigung der Epithese existieren verschiedene Optionen. Sie kann auf die Haut geklebt werden. Dies führt nach einer gewissen Zeit meist zu Hautirritationen. Außerdem ist die Fixation aufwendig und nicht sehr stabil.
  • Alternativ kann eine Epithese an Metallimplantaten fixiert werden, die im Knochen verankert werden. Dies erfordert jedoch offene, d.h. aus der Haut herausragende Implantate. Neben den psychischen Belastungen durch derartige offene Implantate besteht im Übergangsbereich zwischen dem Implantat und der Haut das Risiko chronischer Infektionen.
  • Daher bietet sich eine transkutane, magnetische Fixation an. Dazu wird ein Magnet auf oder in den Schädelknochen implantiert, die Haut entsprechend den individuellen Erfordernissen ausgedünnt und die Epithese mit Hilfe eines zweiten Magneten fixiert.
  • Ein Ausführungsbeispiel ist in 1 dargestellt. Eine Epithese (1) wird mit einem Magneten (2) verbunden. Ein zweiter Magnet (3) wird implantiert. Das subkutane Gewebe (4) kann ausgedünnt werden. Der implantierte Magnet (3) liegt dem Knochen (5) unmittelbar an.
  • In einer Modifikation ist der Magnet (2) über ein Gewinde mit der Epithese verbunden und kann gewechselt werden, so dass die Andruckkraft durch unterschiedlich starke Magnete variiert werden kann.
