BIOMECHANICAL RESPONSE OF THE SPINE: ULTIMATE PROPERTIES AND FAILURE MECHANISMS OF THE LUMBAR SPINE IN FLEXION UNDER DIFFERENT MECHANICAL LOADS

In this study, the ultimate strength in flexion of the lumbar spine was determined. The experiments were carried out on 16 lumbar functional spinal units (two adjacent vertebrae, the intervertebral disc and the connecting ligamentous tissues). The specimens were exposed to a combined static load of bending and shearing until overt rupture occurred. The biomechanical response of the specimens was measured in three directions with a force and moment platform. Mechanical displacement gauges were used to measure vertical displacements (flexion angulation) of the specimens. Photographs were taken after each loading step for determination of horizontal displacements and the centre of rotation. (Author/TRRL)
