F\u00fcr seine Festigkeit sind sowohl Material- als auch Struktureigenschaften von Bedeutung. Trotz des Alterns der Gesellschaft liegen jedoch zu diesen Parametern f\u00fcr Menschen im Greisenalter kaum Daten vor. Deshalb werden im Rahmen der vorliegenden Arbeit Spongiosazylinder von Halswirbelk\u00f6rper III bis Lendenwirbelk\u00f6rper V aus den jeweiligen Zentren der Wirbelk\u00f6rper im Hinblick auf Knochenvolumenanteil, Trabekeldicke, Separation, Anzahl der Trabekeln, Quervernetzung, Verbindungsdichte und Grad der Anisotropie untersucht.<\/jats:p>\n                  <jats:p>Mittels einer Jamshidi-Nadel wurden aus 440 Kadaverwirbeln Proben gewonnen und unter Einsatz der Mikrocomputertomografie analysiert.

Der Knochenvolumenanteil war wie die Verbindungsdichte sowie die Anzahl der Trabekeln und der Quervernetzungen in diesem Wirbels\u00e4ulenabschnitt signifikant h\u00f6her. Dar\u00fcber hinaus fiel der Grad der Anisotropie in der Halswirbels\u00e4ule signifikant geringer aus als in den anderen Wirbels\u00e4ulenabschnitten. Bez\u00fcglich der quantitativen Computertomografie ergab sich in den Halswirbeln ein signifikant h\u00f6herer Knochenmineralgehalt.<\/jats:p>\n                  <jats:p>Auch bei vorliegender
