Estudo experimental do sequenciamento das manobras da ligamentotaxia na descompressão do canal vertebral

Abstract: A descompressão do canal vertebral, para aliviar as estruturas nervosas, pode ser realizada por meio da ligamentotaxia. O objetivo foi analisar a influência da seqüência de realização da ligamentotaxia sobre a descompressão do canal vertebral. Foram utilizados segmentos de vértebras de suínos (Landrace). Um equipamento especialmente desenvolvido foi utilizado para produção de fratura do tipo explosão. Após a tomografia computadorizada, 10 espécimes que melhores apresentavam fraturas do tipo explosão foram fixa… Show more

“…The methods for processing medical images when building 3D-CAD models [33] and material models using the rapid prototyping (RP) techniques [2], [6], [7], [16], [17] have become more and more commonly applied in the process of preoperative planning to visualisation of the bone structures to be operated [4], [28], [29], [30]. In the case of relocation procedure by reposition of a vertebrae after compression fracture made with the use of ligamentotaxis method [13], [19], [24], the visualisation of geometry and bone fragment positions relative to each other is of crucial importance. The geometrical reconstruction of neighbouring vertebrae, into which the transpedicular screws are implanted, is also essential.…”

“…Improper screw implantation through the arc pedicle (insertion outside the vertebral body, perforation of the internal wall and penetration into the spinal canal) may result in serious clinical complications [1], [15], [18], [20], [31]. The aforementioned comments are well justified by clinical practise and the results we have obtained from the experiments performed on the animal spine [9], [13].…”
