[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].

OBJECTIVE

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.

METHODS

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.

RESULTS

There was no significant difference in operation time, surgical blood loss, and incision length between combined group and control group(>0.05). There were no significant differences in anterior height ratio and Cobb angle between two groups before surgery, 1 week and 6 months after surgery(>0.05). The height ratio of anterior margin of the injured spine was significantly improved in both groups at 1 week and 6 months after surgery compared with preoperative period (<0.05), and Cobb angle was significantly reduced in both groups compared with preoperative period (<0.05). There was no statistically significant difference in serum interleukin-6(IL-6), interleukin-8(IL-8), and tumor necrosis factor-α(TNF-α) levels between two groups at 1 d after surgery(>0.05);the serum IL-6, IL-8, and TNF-α levels of combined group were lower than those of control group at 1 week after surgery (<0.05). At 6 months after surgery, ASIA neurological function grade of combined group was C grade in 2 cases, D grade in 23 cases, E grade in 22 cases. In control group, 7 cases was grade C, 26 cases was grade D, 13 cases was grade E, and the difference between two groups was statistically significant(<0.05). The Barthel score of combined group was higher than that of control group at 1 month and 3 months after surgery, and the difference was statistically significant (<0.05);at 6 months after surgery, there was no significant difference in Barthel score between two groups(>0.05).

CONCLUSION

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.
