Objective: To compare the efficacy among stand-alone oblique lateral lumbar interbody fusion (OLIF-SA), OLIF combined with lateral screw internal fixation (OLIF-AF) and OLIF combined with posterior percutaneous pedicle screw internal fixation (OLIF-PF) in the treatment of degenerative lumbar diseases. Methods: The clinical data of patients with degenerative lumbar diseases who underwent OLIF-SA, OLIF-AF and OLIF-PF in the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University from January 2017 to January 2021 were retrospectively analyzed. Patients’ visual analogue score (VAS) and Oswestry disability index (ODI) at 1 week and 12 months postoperatively were recorded, and efficacy of OLIF surgery with different internal fixation methods was evaluated by comparing clinical scores and imaging examinations at preoperative, postoperative and follow-up, and bony fusion and postoperative complications were recorded. Results: A total of 71 patients were included in the study, with 23 males and 48 females, aged (65±11) (34-88) years. There were 25 patients in the OLIF-SA group, 19 patients in the OLIF-AF group, and 27 patients in the OLIF-PF group. Compared with those of OLIF-PF group [(196±46) min and 50 (50, 60) ml], OLIF-SA and OLIF-AF groups had shorter operative time [(97±38) min and (118±48) min] and less intraoperative blood loss [20 (10, 50) ml and 40 (20, 50) ml] (both P<0.001). There was no statistically significant difference in the fusion rate among three groups (P>0.05). No statistically significant differences of VAS and ODI scores were observed among OLIF-SA, OLIF-AF and OLIF-PF groups during preoperative period [VAS: 5.0 (4.0, 6.0), 5.0 (4.0, 6.0) and 5.0 (4.0, 5.3); ODI: 44.0% (35.0%, 47.0%), 46.5% (43.3%, 46.5%) and 43.5% (35.8%, 46.0%)], and at one week postoperatively [VAS: 2.0 (2.0, 3.0), 3.0 (2.0, 3.0) and 2.0 (2.0, 3.0); ODI: 13.0% (12.0%, 18.0%), 21.0% (13.5%, 21.8%) and 16.5%(14.0%, 21.0%)] and final follow-up [VAS: 1.0 (0, 1.0), 1.0 (1.0, 2.0) and 1.0 (1.0, 2.0); ODI: 7.0% (5.0%, 11.0%), 10.0% (7.0%, 14.8%) and 8.0% (6.0%, 12.0%)], respectively (all P>0.05). Conclusion: Compared with OLIF-AF and OLIF-PF, OLIF-SA is a safe and effective surgical method with similar efficacy and fusion rates, decreases the cost of internal fixation, and reduces intraoperative time blood loss.
目的： 比较无内固定斜外侧腰椎椎间融合术（OLIF-SA）、OLIF联合侧方钉棒内固定术（OLIF-AF）和OLIF联合后方经皮椎弓根螺钉内固定术（OLIF-PF）在治疗腰椎退变性疾病中的疗效。 方法： 回顾分析2017年1月至2021年1月于首都医科大学宣武医院神经外科接受了OLIF-SA、OLIF-AF和OLIF-PF治疗的腰椎退变性疾病患者临床资料，术后1周及12个月随访时进行视觉模拟评分（VAS）、Oswestry功能障碍指数（ODI），通过对比术前、术后及随访时的临床评分与影像学检查结果评估不同内固定方式的OLIF手术疗效，记录患者骨性融合时间及术后并发症等。 结果： 共有71例患者被纳入研究，男23例，女48例，患者年龄为（65±11）（34~88）岁，其中OLIF-SA组25例，OLIF-AF组19例，OLIF-PF组27例。OLIF-SA组和OLIF-AF组的手术时间［（97±38）min、（118±48）min、（196±46）min，P<0.001］和术中失血量［20（10，50）ml、40（20，50）ml、50（50，60）ml，P<0.001］都比OLIF-PF组低。3组之间的融合率差异无统计学意义（P>0.05）。OLIF-SA组、OLIF-AF组和OLIF-PF组在术前记录的VAS［M（Q1，Q3）］［5.0（4.0，6.0）分、5.0（4.0，6.0）分、5.0（4.0，5.3）分］和ODI［44.0%（35.0%，47.0%）、46.5%（43.3%，46.5%）、43.5%（35.8%，46.0%）］、术后1周的VAS［2.0（2.0，3.0）分、3.0（2.0，3.0）分、2.0（2.0，3.0）分］和ODI［13.0%（12.0%，18.0%）、21.0%（13.5%，21.8%）、16.5%（14.0%，21.0%）］以及最终随访时记录的VAS［1.0（0，1.0）分、1.0（1.0，2.0）分、1.0（1.0，2.0）分］和ODI［7.0%（5.0%，11.0%）、10.0%（7.0%，14.8%）、8.0%（6.0%，12.0%）］比较，差异均无统计学意义（均P>0.05）。 结论： 与OLIF-AF和OLIF-PF相比，OLIF-SA具有相似的疗效和融合率，省去了内固定的费用，减少了术中时间和术中失血量，是一个安全、有效的手术方法。.
