全内窥镜下后方经椎板间入路腰椎椎间融合术治疗单节段腰椎退行性疾病

目的 评估全内窥镜下后方经椎板间入路腰椎椎间融合术（FE-PLIF）治疗单节段腰椎退行性疾病的临床疗效。方法 2019年3月—2021年3月采用FE-PLIF治疗单节段腰椎退行性疾病患者27例，记录术前和术后3 d、3个月、6个月、1年的腰腿痛视觉模拟量表（VAS）评分和Oswestry功能障碍指数（ODI）。记录手术相关并发症发生情况，术后1年评估椎间融合率。结果 所有手术顺利完成。所有患者术后各时间点腰腿痛VAS评分和ODI较术前显著改善，术后3个月、6个月和1年时较术后3 d显著改善，差异均有统计学意义（P<0.05）。发生术后血肿1例，其余患者均未发生神经或血管损伤并发症。术后1年25例患者椎间骨性融合，融合率为92.6%（25/27）。结论 FE-PLIF治疗单节段腰椎退行性疾病安全有效，术后融合率高。

Full-endoscopic posterior lumbar interbody fusion for treatment of single-segment lumbar degenerative diseases

Objective To evaluate the clinical efficacy of full-endoscopic posterior lumbar interbody fusion(FE-PLIF) for the treatment of single-segment lumbar degenerative diseases. Methods From March 2019 to March 2021, 27 patients with single-segment lumbar degenerative diseases were treated with FE-PLIF. The low back and leg pain visual analogue scale(VAS) scores and Oswestry disability index(ODI) were recorded at pre-operation and postoperative 3 d, 3 months, 6 months and 1 year. The occurrence of surgery-related complications and fusion rate at 1 year after surgery were recorded. Results All the operations were successfully completed. The VAS scores of low back and leg pain and ODI at each time point after surgery were significantly improved compared to pre-operation, and significantly improved at postoperative 3 months, 6 months and 1 year compared to postoperative 3 d, all with a statistical significance(P<0.05). Postoperative hematoma occurred in 1 case, and no complications of nerve or vascular injury occurred in the remaining patients. At postoperative 1 year, 25 patients had bone fusion, with a fusion rate of 92.6%(25/27). Conclusion FE-PLIF is safe and effective in the treatment of single-segment lumbar degenerative diseases, and the postoperative fusion rate is high.
