This is a retrospective study that was done according to clinical and radiological evaluation.
We analyzed the clinical and radiological outcomes of minimally invasive transforaminal lumbar interbody single level fusion.
Minimally invasive transforaminal lumbar interbody fusion is effective surgical method for treating degenerative lumbar disease.
The study was conducted on 56 patients who were available for longer than 2 years (range, 24 to 45 months) follow-up after undergoing minimally invasive transforminal lumbar interbody single level fusion. Clinical evaluation was performed by the analysis of the visual analogue scale (VAS) score and the Oswestry Disability Index (ODI) and the Kirkaldy-Willis score. For the radiological evaluation, the disc space height, the segmental lumbar lordotic angle and the whole lumbar lordotic angle were analyzed. At the final follow-up after operation, the fusion rate was analyzed according to Bridwell's anterior fusion grade.
For the evaluation of clinical outcomes, the VAS score was reduced from an average of 6.7 prior to surgery to an average of 1.8 at the final follow-up. The ODI was decreased from an average of 36.5 prior to surgery to an average of 12.8 at the final follow-up. In regard to the clinical outcomes evaluated by the Kirkaldy-Willis score, better than good results were obtained in 52 cases (92.9%). For the radiological evaluation, the disc space height (p = 0.002), and the whole lumbar lordotic angle (p = 0.001) were increased at the final follow-up. At the final follow-up, regarding the interbody fusion, radiological union was obtained in 54 cases (95.4%).
We think that if surgeons become familiar with the surgical techniques, this is a useful method for minimally invasive spinal surgery.
这是一项根据临床和影像学评估进行的回顾性研究。
我们分析了微创经椎间孔腰椎单节段椎间融合术的临床和影像学结果。
微创经椎间孔腰椎融合术是治疗退行性腰椎疾病的有效手术方法。
本研究对56例接受微创经椎间孔腰椎单节段融合术后随访时间超过2年（范围为24至45个月）的患者进行。通过视觉模拟量表（VAS）评分、奥斯维斯特残疾指数（ODI）和柯卡尔迪 - 威利斯评分进行临床评估。对于影像学评估，分析椎间隙高度、节段性腰椎前凸角和整个腰椎前凸角。在术后最后一次随访时，根据布里德韦尔的前路融合分级分析融合率。
对于临床结果评估，VAS评分从术前平均6.7降至最后一次随访时的平均1.8。ODI从术前平均36.5降至最后一次随访时的平均12.8。根据柯卡尔迪 - 威利斯评分评估的临床结果，52例（92.9%）取得了优于良好的结果。对于影像学评估，最后一次随访时椎间隙高度（p = 0.002）和整个腰椎前凸角（p = 0.001）增加。在最后一次随访时，关于椎间融合，54例（95.4%）获得了影像学融合。
我们认为，如果外科医生熟悉手术技术，这是一种微创脊柱手术的有用方法。
