Einfluß verschiedener Rehydratationszeiten auf die Stabilität und den Wassergehalt von Knochentransplantaten nach Gefriertrocknung, Gammasterilisation und Fettextraktion

Abstract

Based on the presented data rehydration time of 0.5 hours seems to have no disadvantage compared to longer time periods concerning breaking strength. Therefore a longer intraoperative time period seems not to be necessary. This is of advantage for a possible secondary contamination while the allograft is rehydrated. Rehydration after lipid extraction is more effective than rehydration after lyophilization alone. However, the question whether lipid extraction alter bone stability has to be proved in further studies.
