ASSESSMENT OF THE TENSION CONDITION THAT OCCURS WHEN THE BODY IS IMMOBILIZED IN A BOSTON-TYPE PLASTIC CORSET

Abstract

The paper aims to make a theoretical study - using the finite element method, on the local elastic stresses and deformations that appear in the sagital plane under the use of a Boston corset made of polypropylene.The studies prove the fact that the elastic stress state appearing in the xOy plane in the case of the flexion motion is higher whit 18% than the elastic stress state appearing in the same plane in the case of the extension movement and the higher elastic displacements are recorded in the flexion motion. The occurrence of local deformities at the level of the fractured vertebrae may lead to the wrong splicing of the vertebrae, which causes changes in the geometry of the spine.
