Abstract
A pair-controlled study was performed to compare the biomechanical behaviour of implant-reinforced fractured humeri under bending and under torsional loading, respectively. Special interest is related to the fixation potential of a prototype version of an intramedullary nail for stabilisation of subcapital humeral fracture. This nail is especially designed in terms of application for less invasive surgery purposes. In this study, two different modifications of this prototype nail are directly compared with respect to the stabilisation potential in direct comparison to conventionally applied implant techniques (wire technique and plate fixing). First results indicate that fixing of subcapital fracture by this intramedullary nail type provides a good compromise concerning the stabilisation under both loading types, bending and torsion, respectively.
Abstract
Das biomechanische Verhalten implantat-verstärkter gebrochener Oberarmknochen wurde unter Biege- und unter Torsionsbelastung untersucht. Von besonderem Interesse war das Stabilisierungspotential eines minimal invasiv implantierbaren Marknagel-Prototyps zur Fixierung subkapitaler Humerusbrüche. Im Rahmen dieser Untersuchung wurden zwei Modifikationen dieses neuen Marknagels hinsichtlich ihrer Stabilisierungsqualität untersucht und direkt mit den Ergebnissen von mit konventioneller Implantattechnik fixierten Brüchen (K-Drähte und T-Platte) verglichen. Erste Ergebnisse belegen, dass dieser neue Marknagel einen sehr guten Kompromiss hinsichtlich der Stabilisierung sub-kapitaler Brüche des Humerus sowohl unter Biege- als auch unter Torsionsbelastung darstellt.
