To study the effect of posterior internal fixation and fusion on spinal cord nerve function and complications in patients with spinal fracture.

80 patients with spinal fracture treated at our hospital from January, 2017 to August, 2018 were randomly divided into a control group and an experimental group, 30 cases for each group. The control group was treated with anterior internal fixation and fusion, and the experimental group with posterior internal fixation and fusion. The curative effects of the two groups was determined by spinal cord nerve function and operation success rate. The operation indicators, the incidences of complications, and VAS scores were compared between the two groups.

All the 80 patients completed the operation successfully. The total effective rate was higher and the incidence of postoperative complications was lower in the experimental group than in the control group (97.50% vs. 80.00% and 5.00% vs. 20.00%; both P<0.05). The operation time, incision length, and hospitalization time were shorter and the intraoperative bleeding volume was lower in the experimental group than in the control group (allP<0.05). There were no statistical differences in the Cobb angle and anterior high compression ratio between the two groups before the operation (bothP>0.05). The Cobb angle and anterior high compression ratio were better in the observation group than in the control group after the operation (bothP<0.05). One week and 2 and 3 months after the operation, the VAS scores were significantly lower in the observation group than in the control group (allP<0.05).

Posterior internal fixation and fusion is effective in the treatment of spinal fracture, and can reduce the postoperative pain and complications and improve spinal cord nerve function. It is suggested that it should be widely used in clinic.
