研究设计：前瞻性队列研究目的：确定影响成人脊柱畸形（ASD）侧位腰椎椎体间融合（LIF）手术中矢状面对线矫正的因素，并调查每种情况下的矫正程度。文献综述：LIF是ASD的有用手术，但矫正程度可能受到后路截骨术、术中终板损伤或前纵韧带（ALL）断裂的影响。方法：前瞻性检查了30例接受LIF治疗ASD的患者的放射学数据。所有患者均接受了二期手术（LIE后行后路固定）。测量术前、LIF术后和后路固定后的X线片参数，包括节段性前凸角、腰椎前凸（LL）和其他矢状面对准因素。结果：LL从术前的16.5 ° ± 16.7 °矫正到LIF后的33.4 ° ± 13.8 °（P
Study Design: Prospective cohort study.Purpose: To identify factors that affect sagittal alignment correction in lateral lumbar interbody fusion (LIF) surgery for adult spinal deformity (ASD) and to investigate the degree of correction in each condition.Overview of Literature: LIF is a useful procedure for ASD, but the degree of correction can be affected by posterior osteotomy, intraoperative endplate injury, or anterior longitudinal ligament (ALL) rupture.Methods: Radiographical data for 30 patients who underwent LIF for ASD were examined prospectively. All underwent two-stage surgery (LIE followed by posterior fixation). Radiographical parameters were measured preoperatively, after LIF, and after posterior fixation; these included the segmental lordotic angle, lumbar lordosis (LL), and other sagittal alignment factors.Results: LL was corrected from 16.5 degrees +/- 16.7 degrees preoperatively to 33.4 degrees +/- 13.8 degrees after LIF (p
