第一节脊柱骨折（Section 1 fracture of spine） The sixty-fifth chapter is fracture of spine and pelvis Section 1 fracture of spine Fracture of the (Spine) is very common, accounting for about 5%, 6% of the total fractures, of which thoracolumbar fracture is the most common. Spinal fractures can be complicated by spinal cord or cauda equina injuries, especially those with cervical spine fractures associated with spinal cord injuries. It is reported to be as high as 70%, which can cause severe disability or even loss of life. Each vertebra is divided into two parts: vertebral body and appendix. The entire spine can be divided into the anterior, middle, and posterior three columns (FIGS. 65, 1). In the column and posterior column wrapped the spinal cord and cauda equina injury, the area can affect the nervous system, especially in the first half, column injury, bone fragments and nucleus pulposus can process lumbar spinal cord injury, so for each case of spinal fracture must be aware of whether the column injury. Thoracolumbar Duan Jizhu (Tl. At the confluence of two physiological arcs, where stress concentration occurs, fracture is very common here. The anatomical structure of figure 65 L but the stability of thoracolumbar, three anterior column, the longitudinal axis of the vertebral body before 2 / 3, first half of the annulus and the anterior longitudinal ligament in the vertebral column; - after 1 / 3, annulus and the latter part of the posterior longitudinal ligament; joint capsule, posterior column: yellow ligament, bony neural arch, supraspinous ligament, interspinal ligament and articular process Etiology and classification of violence are the major causes of thoracolumbar fracture. Does the direction of violence pass through the X, Y, and Z axes?. There are six kinds of motion in the spine: compression, traction and rotation on the Y axis; flexion, extension and lateral movement on the X axis; lateral bending and forward and backward movements on the Z axis (Figs 65, 1
