Le basi biomeccaniche del trattamento delle fratture toraco-lombari

Abstract

The key objectives for the ideal surgical treatment of thoracolumbar fractures are: immediate stability for full weight bearing restoration and maintenance of the sagittal alignment decompression of the spinal canal, where required limitation of the fixation construct to the injured segments These goals can be successfully achieved by a thorough understanding of the biomechanical concepts of the spine and spinal injuries. Posterior only short segment instrumentation and/or fusion do not achieve these goals. Understanding of spine biomechanics has evolved to the present system of fracture classification based on the pathomechanism of the injury pattern. This classification system based on biomechanics allows the spine surgeon to understand the forces involved and provides the surgeon with the concept to restore the spine to near normal alignment and function.Today’s surgical techniques and modern spinal fixation constructs allow the spine surgeon to accomplish these goals.Surgical procedures which do not fulfil these requirements should not be performed!
