Abstract: BACKGROUND: At present, non-fusion internal fixation is usually used in the treatment of jumping spinal fracture which is prone to severe degeneration of adjacent intervertebral discs, broken nails, broken rods, and difficulties in spine stiffness and recovery. In particular, it is impossible to avoid the second internal fixation removal operation, resulting in re-injury of the tissue.  
OBJECTIVE: To analyze the clinical effect of external fixation of spinal elastic stress in the treatment of jumping spinal fracture.
METHODS: Sixty-five patients with jumping spinal fracture from First Affiliated Hospital of University of South China and Guochang Bi Orthopedics and Traumatology Hospital of Chongqing from July 2016 to July 2019 were selected, including 37 males and 28 females, aged 20-55 years old. They were divided into two groups according to the treatment methods. The control group (n=32) received pedicle screw insertion and internal fixation, and the trial group (n=33) received external fixation and elastic stress treatment. The anterior edge high loss rate, Oswestry dysfunction index, visual analogue scale score, and callus formation were compared between the two groups before and after surgery. This study was approved by the Ethics Committee of First Affiliated Hospital of University of South China and Guochang Bi Orthopedics and Traumatology Hospital of Chongqing.  
RESULTS AND CONCLUSION: (1) The high loss rate of anterior edge of injured vertebra after surgery was lower than that before surgery in both groups (P < 0.05). The high loss rate of the anterior edge of the injured vertebra was lower in the trial group than that in the control group at 1 week and 3 months after operation (P < 0.05). (2) Postoperative Oswestry disability index and visual analogue scale score in both groups were lower than those before surgery (P < 0.05). Oswestry disability index and visual analogue scale score were lower in the trial group than those in the control group at 1 week and 3 months after surgery (P < 0.05). (3) The callus formation rate in the trial group was higher than that in the control group at 3 and 12 months after surgery (P < 0.05). (4) The results showed that the external fixation of the spine with elastic stress was more effective than that of the traditional pedicle screw in the treatment of jumping spinal fractures.
