ObjectiveTo observe the efficacy of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) assisted by Quadrant channel on patients with single segment lumbar disease. MethodsA total of 60 patients with single segment lumbar disease were selected and randomly assigned to observation group (30 cases, undergoing MIS-TLIF assisted by Quadrant channel), and control group (30 cases, undergoing conventional open surgery). The perioperative related indices, creatine kinase (CK) level, T2 relaxation time, Oswestry dysfunction index (ODI), VAS scores of lumbargo and skelalgia, and incidence of complications were compared between the two groups. ResultsThe difference of operation duration was not statistically significant between the two groups (P＞0.05); moreover, the observation group yielded less intraoperative bleeding volume, postoperative drainage volume, and shorter hospital stays as compared with the control group (all P＜0.05). The observation group obtained lower CK level 3 days after operation, shorter T2 relaxation time, lower scores of ODI, and VAS of lumbargo and skelalgia 3 months after operation in comparison of the control group (all P＜0.05). There was no statistically significant difference in the incidence of complications between the observation group and the control group (3.33% vs. 13.33%, P＞0.05). ConclusionEmploying MIS-TLIF assisted by Quadrant channel on patients with single segment lumbar disease has slight operative trauma, and it can promote rapid recovery of patients, with low prevalence of complications. Thus it is worthy of promotion.
