Abstract:Objective To investigate the clinical effects of unilateral biportal endoscopic (UBE) technique and traditional posterior lumbar interbody fusion (PLIF) in treatment of lumbar degenerative diseases.Methods 80 patients with lumbar degenerative diseases from August 2018 to August 2021 were selected as the research subjects. Patients treated with UBE technique and those treated with traditional PLIF were defined as study group (n = 30) and control group (n = 50), respectively. Surgery-related indicators, visual analogue scale (VAS) of pain, Japanese Orthopaedic Association (JOA) score of low back pain, serum inflammatory factor levels and postoperative complications were compared between the two groups.Results The intraoperative blood loss and postoperative drainage volume of study group were less than those of the control group (P < 0.05), and postoperative hospital stay of study group was shorter than that of the control group (P < 0.05). After operation, the VAS, TNF-α and IL-6 levels of study group were lower than those of the control group (P < 0.05). The JOA score and IL-4 level were higher than those of the control group (P < 0.05). The incidence rate of postoperative complications in the study group and the control group were 10.00% and 12.00%, respectively (P > 0.05).Conclusion UBE technique is effective and safe in treatment of lumbar degenerative diseases. It can effectively improve surgery-related indicators and inflammatory factor levels, and alleviate postoperative pain, with safety.
