Abstract：Objective To investigate the application effect of oblique lumbar interbody fusion (OLIF) combined with posterior approach screw-rod system in lumbar spondylolisthesis. Methods A total of 85 patients with lumbar spondylolisthesis in Shangrao City People′s Hospital from June 2019 to June 2021 were selected for retrospective study. According to the surgical methods, the patients were divided into 40 cases in the nail rod group and 45 cases in the combined group. The nail rod group was treated with posterior intervertebral fusion and nail rod system, and the combined group was treated with OLIF combined with approach screw-rod system. The intraoperative blood loss, operation time,postoperative infection rate, symptom relief rate, lumbar fusion rate and length of hospital stay were compared between the two groups. Results There was no significant difference in the intraoperative infection rate between the two groups(P＞0.05). The operation time of the combined group was longer than that of the nail rod group, but the intraoperative blood output of the combined group was less than that of the nail rod group, the differences were statistically significant(P＜0.05). The remission rate of symptoms in the combined group was higher than that in the nail rod group, the difference was statistically significant (P＜0.05). The lumbar fusion rate of the combined group was higher than that of the nail rod group, and the length of hospital stay of the combined group was lower than that of the nail rod group, the differences were statistically significant (P＜0.05). Conclusion OLIF combined with posterior approach screw-rod system in the treatment of patients with lumbar spondylolisthesis can reduce intraoperative blood loss, shorten the operation time, improve symptoms, and promote bone graft fusion and postoperative recovery.
