The lowest lumbar vertebra is situated just above the sacrum, or triangular bony plate that extends from the hip line to the middle of the buttocks. There is a varying degree of slippage of the body of one vertebra relative to the adjacent vertebra, owing to ligamentous injury and the jumped facets, with, therefore, a high predisposition for injury to the spinal cord. As compression fractures generally result in a loss of height of the vertebral body, restoring that height is the goal of surgical treatment. LSTVs include sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. The lumbar region is situated between the thoracic, or chest, region of the spine, and the sacrum. They have backbones and are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone. The vertebral arch has 3 bony protrusions: a prominent spinous process in the middle and two transverse processes on either side.
