The aim of the present study was to investigate patterns of spine sagittal alignment in asymptotic patients using radiological analysis. A number of studies focused on investigating normal patterns of spinal and pelvic alignment in Chinese populations, while few have evaluated Caucasian and other Asian populations. A total of 10 relevant pelvic and spinal parameters, including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), cervical lordosis (CL), thoracic kyphosis (TK), sagittal vertical axis (SVA), lumbopelvic lordosis angle (PR-T12), spino-sacral angle (SSA) and sacral pelvic angle (SPA), were evaluated in asymptomatic Chinese adults from Beijing, aged 21-65 years. Correlations among these parameters, as well as between these parameters and age, and associations with gender and body mass index (BMI) were assessed using Pearson's correlation analysis. A total of 39 males and 46 females, aged 50.9±13.2 and 41.8±13.6 years, respectively, were enrolled in the present study. The results of PI, PT, SS, LL, TK, CL, SVA, PR-T12, SSA and SPA values suggested that age was positively correlated with TK, CL and SVA, while it was negatively correlated with LL, PR-T12 and SSA. SSA and SVA were revealed to differ significantly between sexes. It was also demonstrated that LL and TK may be associated with BMI. In conclusion, the results of the present study indicate that spinopelvic parameters in the asymptomatic Chinese Han population (in Beijing) are correlated with age and may be associated with individuals' ethnicity, sex and BMI. The results of the current study may provide a basis for the restoration of LL or similar diseases.
本研究的目的是通过影像学分析调查无症状患者的脊柱矢状面排列模式。许多研究集中于调查中国人群脊柱和骨盆排列的正常模式，而评估高加索人和其他亚洲人群的研究较少。对来自北京的21至65岁无症状中国成年人，评估了总共10个相关的骨盆和脊柱参数，包括骨盆入射角（PI）、骨盆倾斜角（PT）、骶骨斜率（SS）、腰椎前凸（LL）、颈椎前凸（CL）、胸椎后凸（TK）、矢状垂直轴（SVA）、腰骨盆前凸角（PR-T12）、脊柱-骶骨角（SSA）和骶骨骨盆角（SPA）。使用Pearson相关分析评估这些参数之间的相关性，以及这些参数与年龄之间的相关性，以及与性别和体重指数（BMI）的关联。本研究共纳入39名男性和46名女性，年龄分别为50.9±13.2岁和41.8±13.6岁。PI、PT、SS、LL、TK、CL、SVA、PR-T12、SSA和SPA值的结果表明，年龄与TK、CL和SVA呈正相关，而与LL、PR-T12和SSA呈负相关。SSA和SVA在性别之间存在显著差异。还表明LL和TK可能与BMI有关。总之，本研究结果表明，无症状中国汉族人群（北京）的脊柱骨盆参数与年龄相关，可能与个体的种族、性别和BMI有关。本研究结果可为LL或类似疾病的恢复提供依据。
