Abstract：
OBJECTIVE: Spinopelvic sagittal alignment is crucial for assessing balance and determining treatment efficacy in patients with adult spinal deformity (ASD). Only a limited number of reports have addressed spinopelvic parameters and lumbosacral transitional vertebrae (LSTV). Our primary objective was to study spinopelvic sagittal parameter changes in patients with LSTV. A secondary objective was to investigate clinical symptoms and quality of life (QOL) in patients with LSTV.
METHODS: In this study, we investigated 371 participants who had undergone medical check-ups for the spine. LSTV was evaluated using Castellvi\'s classification, and patients were divided into LSTV+ (type II-IV, L5 vertebra articulated or fused with the sacrum) and LSTV- groups. After propensity score matching for demographic data, we analyzed spinopelvic parameters, sacroiliac joint degeneration, clinical symptoms, and QOL for these two participant groups. Oswestry Disability Index (ODI) scores and EQ-5D (EuroQol 5 dimensions) indices were compared between the two groups.
RESULTS: Forty-four patients each were analyzed in the LSTV + and LSTV- groups. The LSTV + group had significantly greater pelvic incidence (52.1 ± 11.2 vs. 47.8 ± 10.0 degrees, P = 0.031) and shorter pelvic thickness (10.2 ± 0.9 vs. 10.7 ± 0.8 cm, P = 0.018) compared to the LSTV- group. The \"Sitting\" domain of ODI (1.1 ± 0.9 vs. 0.6 ± 0.7, P = 0.011) and \"Pain/Discomfort\" domain of EQ-5D (2.0 ± 0.8 vs. 1.6 ± 0.7, P = 0.005) were larger in the LSTV + group.
CONCLUSIONS: There was a robust association between LSTV and pelvic sagittal parameters. Clinical symptoms also differed between the two groups in some domains. Surgeons should be aware of the relationship between LSTV assessment, radiographic parameters and clinical symptoms.

摘要：
目的：脊柱骨盆矢状位对评估成人脊柱畸形（ASD）患者的平衡和确定治疗效果至关重要。只有有限数量的报告涉及脊柱骨盆参数和腰s骨移行椎骨（LSTV）。我们的主要目的是研究LSTV患者的脊柱骨盆矢状面参数变化。次要目的是调查LSTV患者的临床症状和生活质量（QOL）。
方法：在本研究中，我们调查了371例接受脊柱体检的参与者.LSTV使用Castellvi分类进行了评估，并将患者分为LSTV+（II-IV型，L5椎骨与骶骨铰接或融合）和LSTV组。人口统计数据的倾向得分匹配后，我们分析了脊髓骨盆参数，骶髂关节变性,临床症状,以及这两个参与者组的QOL。比较两组Oswestry残疾指数(ODI)评分和EQ-5D(EuroQol5维度)指标。
结果：分析了LSTV+和LSTV-组的44例患者。LSTV+组的骨盆发病率明显更高（52.1±11.2vs.47.8±10.0度,P=0.031）和较短的骨盆厚度（10.2±0.9vs.10.7±0.8cm,P=0.018）与LSTV组相比。ODI的“坐”域(1.1±0.9与0.6±0.7，P=0.011）和EQ-5D的“疼痛/不适”域（2.0±0.8vs.1.6±0.7，P=0.005）在LSTV+组中较大。
结论：LSTV与骨盆矢状面参数之间存在密切关联。在某些领域，两组之间的临床症状也有所不同。外科医生应该意识到LSTV评估之间的关系，影像学参数和临床症状。
