Diese Studie untersucht, ob durch eine intraoperative ESWT die Heilungsrate bei Rekonstruktion des Kahnbeins bei Pseudarthrose mittels nicht-gef\u00e4\u00dfgestieltem Knochentransplantat verbessert oder beschleunigt werden kann.<\/jats:p><jats:p>\n          Patienten und Methoden In einer noch laufenden prospektiven Studie werden Patienten mit Rekonstruktion des Kahnbeins bei Pseudarthrose mit einem nicht-vaskularisierten Knochentransplantat randomisiert in Patienten mit (Interventionsgruppe) oder ohne (Kontrollgruppe) zus\u00e4tzlicher intraoperativer ESWT. In 6-w\u00f6chigen Abst\u00e4nden erfolgen postoperativ klinische und radiologische Untersuchungen, nach 12, 18 und bei Bedarf 24\u2005Wochen zus\u00e4tzlich auch eine Computertomographie (CT). Interventions- und Kontrollgruppe werden hinsichtlich der prozentualen Durchbauung der Span-Kahnbein-Kontaktfl\u00e4che distal und proximal des interponierten Knochenblocks postoperativ nach 12, 18 und 24\u2005Wochen sowie der Ausheilung nach 24\u2005Wochen verglichen. Zum Zeitpunkt der Datenerhebung waren bei 35\u2005Patienten der Interventions- und 33\u2005Patienten der Kontrollgruppe die vorgesehenen Nachuntersuchungen erfolgt.<\/jats:p><jats:p>\n          Ergebnisse 24\u2005Wochen postoperativ war bei 27\u2005Patienten (77\u2005%) der Interventionsgruppe und 20\u2005Patienten (61\u2005%) der Kontrollgruppe das Kahnbein geheilt. Die prozentuale Durchbauungsrate des Kahnbeins betrug proximal des Knochenblocks nach 12, 18 und 24\u2005Wochen bei den als ausgeheilt eingestuften Kahnbeinen der ESWT-Gruppe jeweils 80\u2005%, 84\u2005% und 86\u2005%, in der Kontrollgruppe 74\u2005%, 81\u2005% und 84\u2005%. Distal des Knochenblocks betrug sie in der ESWT-Gruppe 91\u2005%, 94\u2005% und 95\u2005%, in der Kontrollgruppe 77\u2005%, 90\u2005% und 94\u2005%. Die Durchbauung war distal 12\u2005Wochen postoperativ in der ESWT-Gruppe signifikant h\u00f6her als in der Kontrollgruppe.<\/jats:p><jats:p>\n          Schlussfolgerung Eine einmalige ESWT intraoperativ verbessert die Ausheilungsrate bei Rekonstruktion des Kahnbeins bei Pseudarthrose mit einem nicht-vaskularisierten Knochentransplantat und beschleunigt die Knochenheilung in den ersten
