Numerical and experimental stress analysis of an external
This paper presents research results of a stress analysis of a Sarafix external fixation system, applied to an unstable tibia fracture. A stress analysis was performed using Finite Element Analysis (FEA) and experimental stress measurements using strain gauges. Research was performed on the Sarafix external fixation system controlling values and directions of principal stresses at the measuring points in the case of axial compression. Sarafix proved to be mechanically stable, confirming good clinical results in the treatment of bone fractures.
