Mittels bisegmentalen Grund-Deckplatten-Winkels (bGDW) wurde die Stellung des verletzten Wirbels\u00e4ulenabschnitts beschrieben. Normalwerte f\u00fcr die bGDW wurden anhand von Literaturdaten angenommen. Die Ver\u00e4nderung des bGDW im zeitlichen Verlauf wurde unter Einbeziehung der Knochenqualit\u00e4t in Hounsfield Units (HU), der Verletzungsschwere nach AOSpine und des Patientenalters und -geschlechts analysiert.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Ergebnisse<\/jats:title>\n                <jats:p>Es wurden 151 Datens\u00e4tze ausgewertet.
