Support system for the spine condition assessment

Abstract

In the article is proposed the method for preoperative spinal structures state prediction based on biomechanical studies of the spine stress -strain state. Is developed the technology and are shown the results of research for spine ligaments sprains performed at INSTRON installation. Also are shown the spine departments and implants geometric and computer models.Spine operations are divided to two main categories: operations of decompression during which pressure upon nerve roots is removed, and merge operations during which two or more vertebras are spliced among themselves, forming motionless connection. Many stabilizing operations belong to decompressive-stabilizing type, during which operations of both types are combined.Methods of visualization and diagnostics of the spine condition don't contain information required for the choice of reasonable correction method. For example, the effective operation treatment method of vertebrae's hernia often leads to postoperative complications and to diseases of in other spine departments. The issue of expediency and reduction degree of vertebras concerning a sacrum at a spondilolistez in surgical practice has no unambiguous decision.For ensuring patient treatment it is necessary to have opportunity to carry out preoperative forecasting of spine structures condition as a result of pathology elimination. Such forecasting can be constructed on the basis of biomechanical study of the spine stress -strain state. The adequate model of the patient spine should reflect: 1) individual geometrical parameters of spine structures 2) strain conditions when performing certain movements; 3) boundary conditions for the allocated spine department; 4) mechanical properties of spine structure.
