Protective effect of the thoracic cage on parenchyma in response to trauma direction in blunt thoracic trauma: an experimental study.

Background: We aimed to investigate the protective potential of the thoracic cage on the parenchyma in response to blunt trauma from different directions in an animal model.

Methods: Female Wistar albino rats were divided into control, anterolateral, lateral and posterolateral trauma groups, with six rats in each group. A weight of 500 g was dropped from a height of 40 cm on the left hemithorax to produce an energy of 1.

Mechanical performance of hybrid Ilizarov external fixator in comparison with Ilizarov circular external fixator.

Objective: The aim of this study was to determine the stiffness characteristics of the standard and hybrid Ilizarov fixators.

Design: Five different frame models (one standard and four hybrid Ilizarov) were designed. Four full rings were used in the standard Ilizarov frame.
