Finite Element Study: Locus of Axis of Rotation of T11-T12 and T12-L1 Segments under Flexion/Extension and Axial Rotation Configurations | In human, the thoracolumbar junction (TLJ) is a transitional region where the normal kyphotic thoracic region shifts to the normal lordotic lumbar region; the coronally oriented facet joints of the thoracic region transform to the sagitally oriented facet joints of the lumbar; and the relatively immobile thoracic region changes to the relatively mobile lumbar region. The different anatomical characteristics at the functional spinal units (FSUs) of T11- T12 and T12-L1 provide an opportunity to study the associations between pathoanatomical changes in these two levels. Hence, it is of interest to investigate the biomechanical responses of the spinal motion segments T11-T12 and T12-L1, which possess the transitional vertebra T12, to determine whether the biomechanical kinematic properties reflect these anatomical changes between these FSUs. The movement of a FSU is dependent upon several parameters, namely its complex geometry, facet articulations and material characteristics of the ligament us tissues, intervertebral discs, and upon the applied load vectors.
