The diagram of spinal joints release technique. A The screws were placed through the Wiltse approach, the screws of the injured vertebra were pulled out, and the multifidus muscle was stripped from the side of the spinous process and the surface of the lamina, broken in the middle, and pulled to both sides. B The spinous process, lamina, and bilateral articular processes were removed and the existing nerve roots were protected. C After clearance of intervertebral space and disconnection of anterior longitudinal ligament and callus, release the anterior 1/2 of bilateral fibrous rings of the intervertebral disc as reduction hinge for patients who were still rigid. D Pre-bend the connecting rod into a physiological radian and place it alternately on both sides. There was no obvious shortening of the spine and spinal cord. Local autologous granular bone was implanted into the intervertebral space. If the posterior 1/2 of the endplate was not damaged, the local autologous granular bone was placed in the anterior 1/2 of the intervertebral space, and the Cage was placed in the posterior 1/2 of the intervertebral space
