Summary
In order to improve gliding function of damaged flexor tendons in chickens, we topically applied enriched collagen solution (ECS) to the tendon sheaths of severed tendons. Previous studies using the same experimental model showed improvement of gliding function in the damaged tendons biomechanically and increased collagenolytic activity in the area of the damage after application of ECS. In the present study we evaluated the influence of ECS on peritendinous adhesion formation and on the healing process of the tendons histologically. We found that topically applied ECS reduced adhesion formation, mostly during the first week, without adversely affecting tendon healing or scar maturation.
Zusammenfassung
Um die Gleitfähigkeit der Beugesehnen nach Verletzungen zu verbessern, erfolgte die Lokalapplikation von Collagenlösung in die Sehnenscheide verletzter Sehnen beim Hühnchen. In vorangegangenen Untersuchungen mit dem gleichen experimentellen Modell konnte nachgewiesen werden, daß dabei die Gleitfähigkeit mechanisch zu verbessern und die collagenolytische Aktivität im Verletzungsbereich zu erhöhen war. Die vorliegenden Ergebnisse zeigen nach Lokalapplikation von Collagen-lösung und Sehnenscheidenbereich eine verminderte Adhäsionsreaktion insbesondere in der ersten Woche. Die Sehnenheilung und Narbenreifung waren unverändert.
