The aim of this study is to compare the clinical and radiological outcome of minimally invasive posterior lumbar interbody fusion (MI-PLIF) in revision and primary cases.
In a retrospective study, we compared the clinical and radiological results of MI-PLIF for lytic spondylolisthesis (n = 28) and recurrent radiculopathy after herniated disc surgery (n = 28). Clinical outcome was assessed using the visual analogue score (VAS) and Oswestry Disability Index (ODI). Quality of life was assessed with the Euroqol-5d (EQ5D), the EQ5D VAS and the WHOQOL-BREF.
The follow-up was 5.1 (SD 2.3) years. The decrease in VAS scores was significant and comparable in both groups. We found significantly better ODI and quality of life scores for the patients with lytic spondylolisthesis. The radiological outcome showed only one non-union, and subsidence occurred in both groups at an equal amount.
The MI-PLIF technique is a safe procedure with only few complications and a high fusion rate. It was successful in both groups, but the quality of life and ODI are better in primary cases.
本研究旨在比较微创后路腰椎椎间融合术（MI-PLIF）在翻修病例和初次手术病例中的临床及影像学结果。
在一项回顾性研究中，我们比较了MI-PLIF治疗溶骨性椎体滑脱（n = 28）和椎间盘手术后复发性神经根病（n = 28）的临床及影像学结果。使用视觉模拟评分（VAS）和Oswestry功能障碍指数（ODI）评估临床结果。采用欧洲五维度健康量表（EQ5D）、EQ5D视觉模拟量表和世界卫生组织生存质量简表（WHOQOL-BREF）评估生活质量。
随访时间为5.1（标准差2.3）年。两组VAS评分的降低均显著且相当。我们发现溶骨性椎体滑脱患者的ODI和生活质量评分明显更好。影像学结果显示仅1例骨不连，两组沉降发生率相同。
MI-PLIF技术是一种安全的手术，并发症少，融合率高。两组手术均获成功，但初次手术病例的生活质量和ODI更好。
