Abstract：
BACKGROUND: Understanding spinal sagittal balance is crucial for assessing and treating spinal deformities in pediatric populations.
OBJECTIVE: The aim of the present observational study is to examine the parameters of sagittal alignment of the regional spine and spinopelvic region in asymptomatic pediatric populations and the characteristics of these parameters with age and sex.
METHODS: We enrolled 217 participants, consisting of 112 males (51.6%) and 105 females (48.4%), aged between 4 and 15 years, with an average age of 12.19 years. Pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, thoracic kyphosis, T1 slope, C7 slope, cervical sagittal vertical axis, and C2-7 Cobb angle were measured. Three spine surgeons conducted radiographic measurements utilizing the PACS software. The measurement reliability was assessed through ICCs.
RESULTS: Our results show significant age-related changes in pelvic tilt and cervical sagittal vertical axis, with notable gender differences in pelvic tilt, lumbar lordosis, and thoracic kyphosis. Girls have larger PT, boys have larger cSVA. PI, PT, and cSVA also differ among different age groups. Correlation analysis shows that a series of relationships that align with adult population patterns between pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, and thoracic kyphosis.
CONCLUSIONS: Significant variations in PT and cSVA across diverse age cohorts highlights notable disparities in the distribution of PT and cSVA values within the pediatric population. Gender-based differences in PT, LL, and TK and correlation in spinopelvic parameter could enhances our understanding of compensatory mechanisms.

摘要：
背景：了解脊柱矢状面平衡对于评估和治疗小儿脊柱畸形至关重要。
目的：本观察性研究的目的是检查无症状儿童人群中脊柱区域和脊柱骨盆区域矢状位排列的参数以及这些参数随年龄和性别的特征。
方法：我们登记了217名参与者，由112名男性(51.6%)和105名女性(48.4%)组成，年龄在4至15岁之间，平均年龄为12.19岁。盆腔发病率,骨盆倾斜,骶骨斜坡,腰椎前凸,胸椎后凸,T1斜率,C7斜坡,颈椎矢状面垂直轴,测量C2-7的Cobb角。三名脊柱外科医生利用PACS软件进行了射线照相测量。通过ICC评估测量可靠性。
结果：我们的结果显示骨盆倾斜和颈椎矢状垂直轴的显着年龄相关变化，骨盆倾斜有明显的性别差异，腰椎前凸,和胸椎后凸.女孩有更大的PT，男孩有更大的CSVA。PI,PT,cSVA在不同年龄段之间也不同。相关分析表明，一系列的关系，符合成人人口模式之间的骨盆发病率，骨盆倾斜,骶骨斜坡,腰椎前凸,和胸椎后凸.
结论：不同年龄队列中PT和cSVA的显著差异突出了儿科人群中PT和cSVA值分布的显著差异。PT的性别差异，LL,TK和脊髓骨盆参数的相关性可以增强我们对代偿机制的理解。
