Resumen

Se desarrolla un procedimiento, mediante grafismo por ordenador, que posibilita el modelado geométrico de la columna lumbar, en base al cual podemos reconstruir, sintetizar y visualizar su anatomía y funcionalidad. Este modelo incorpora una gran potencialidad como soporte para el diagnóstico, exploración, estudios anatómicos, así como planificaciones de intervenciones quirúrgicas.

El diseño que se plantea permite:

  • 1.–

    Valorar la morfología de la columna lumbar desde el punto de vista anatómico.

  • 2.–

    Manipular la imagen anatómica mediante animación gráfica computarizada (giros, traslaciones, rotaciones, etc.).

  • 3.–

    Integrar todas las imágenes de un mismo paciente y poder así localizar uná posible lesión a nivel lumbar.

  • 4.–

    Seleccionar una vía de abordaje en la RM que nos lleve a la proximidad de una posible lesión a este nivel.

  • 5.–

    Proceder con mayor seguridad a la cirugía, evitando lesiones neurológicas.

Summary

Using computerized graphics, we have developed a method that enables geometric modelling of the lumbar column. On the basis of this, it is possible to reconstruct, synthesize and visualize the anatomy and degree of functionality of this part of the spine. The model has great potential in diagnosis, exploration, anatomical studies and in the planning of surgical interventions.

The proposed design permits the following:

  • 1.–

    Evaluation of the morphology of the lumbar column from the anatomical point of view.

  • 2.–

    Handling of the anatomical image by computerized graphic animation (turns, translations, rotations, etc.).

  • 3.–

    The integration of all the images of a single pahent, thus enabling the localization of possible lesions at lumbar level.

  • 4.–

    The selection of a route of intervention by MR that enables one to approach a possible lesion at this level.

  • 5.–

    The possibility of safer surgical interventions avoiding neurologicallesions.
