[Effects of short-segment pedicle screw internal fixation surgery combined with hyperbaric oxygen treatment for acute spinal injury on the morphology and function of the spine]

To explore effect of short-segment pedicle screw internal fixation combined with hyperbaric oxygen in treating acute spinal fractures and its influence on recovery of spinal nerve function.A total of 96 patients with acute spinal fracture admitted from February 2017 to March 2020 were divided into combined group and control group, with 48 cases in each group. Both groups were treated with short-segment pedicle screw internal fixation. The combined group was given hyperbaric oxygen after surgery. The operation time, surgical blood loss, incision length and other general operation conditions between two groups were recorded. The differences in spinal morphology and function, Ameraican Spinal Injury Assiciation(ASIA) neurological function grade, serum inflammatory factors and ability of daily living activities were observed before and after surgery.There was no significant difference in operation time, surgical blood loss, and incision length between combined group and control group(Short-segment pedicle screw internal fixation combined with hyperbaric oxygen for the treatment of acute spinal fractures is beneficial to the recovery of spinal nerve function after surgery, and has a certain effect on the early improvement of the patients' activities of daily living.
