Imaging Anatomical Research on the Operative Windows of Oblique Lumbar Interbody Fusion

To provide applied anatomical evidence of the preoperative assessment of oblique lumbar interbody fusion (OLIF), the anatomical parameters of the OLIF operative window were observed through computed tomography angiography (CTA). We selected imaging data from 60 adults (30 males, 30 females) who underwent abdominal CTA and T12-S1 vertebral computed tomography (CT) with three-dimensional reconstruction. The OLIF operative windows at the L1-2, L2-3, L3-4, L4-5 and L5-S1 levels were as follows: the vascular window, bare window, psoas major window, ideal operative window, and actual operative window. Each level's actual operative window was statistically analyzed based on an actual operative window of P = 0.000), and the percentages of the actual surgical window were 69%, 66%, 53%, 56% and 43%, respectively. The actual surgical window was

为给斜腰椎椎间融合术（oblique lumbar interbody fusion, OLIF）的术前评估提供应用解剖学依据，本研究通过计算机断层血管造影（computed tomography angiography, CTA）观察OLIF手术操作窗的解剖参数。我们选取了60名接受腹部CTA检查且行T12-S1椎体三维重建计算机断层扫描（computed tomography, CT）的成年人影像数据，其中男性30例、女性30例。L1-2、L2-3、L3-4、L4-5及L5-S1节段的OLIF手术操作窗分别为：血管窗、裸区窗、腰大肌窗、理想手术窗与实际手术窗。以P=0.000的实际手术窗为基准，对各节段的实际手术窗进行统计学分析，各节段实际手术窗占比分别为69%、66%、53%、56%及43%。实际手术窗
