摘要：

This paper presents research results of a stiffness analysis of a Sarafix external fixation system. The stiffness property of the external fixator affects the local biomechanical and biological environment of fracture healing. The research has been conducted in a case when one of the Sarafix unilateral biplanar fixator configurations has been applied to a tibia with an open fracture. A stiffness analysis was performed using FEA and experimental testing under three types of loads: axial compression, AP ( anterior-posterior) four-point bending and torsion. 3D geometrical and FEM model of the fixator configuration was formed using CATIA V5 software system and a structural analysis was performed afterwards. Verification of the results obtained from a structural analysis was carried out through experimental testing by comparing values of an appropriate component of displacement at the point of load.
