Design of External Fixators used in Traumatology and Orthopaedics – Treatment of Fractures of Pelvis and its Acetabulum

This article is focused on the design of external fixators applied in traumatology and orthopaedics. These fixators have been designed in the Czech Republic and they can be used in the treatment of open and unstable (i.e. complicated) fractures of limbs, pelvis and its acetabulum. Two versions (i.e. old and new) are compared and evaluated. Numerical modelling (i.e. Finite Element Method), together with CAD modelling, experiments, material engineering and nanotechnology are presented as a support for developing of a new design of external fixators.
