Abstract：
UNASSIGNED: Sagittal imbalance can be caused by various etiologies and is among the most important indicators of spinal deformity. Sagittal balance can be restored through surgical intervention based on several radiographic measures. The purpose of this study is to review the normal parameters in the sitting position, which are not well understood and could have significant implications for non-ambulatory patients.
UNASSIGNED: A systematic review was performed adhering to PRISMA Guidelines. Using R-software, the weighted means and 95% confidence intervals of the radiographic findings were calculated using a random effect model and significance testing using unpaired t-tests.
UNASSIGNED: 10 articles with a total of 1066 subjects reported radiographic measures of subjects with no spinal deformity in the sitting and standing position. In the healthy individual, standing sagittal vertical axis -16.8°was significantly less than sitting 28.4° (p < 0.0001), while standing lumbar lordosis 43.3°is significantly greater than sitting 21.3° (p < 0.0001). Thoracic kyphosis was not significantly different between the two groups (p = 0.368). Standing sacral slope 34.3° was significantly greater than sitting 19.5° (p < 0.0001) and standing pelvic tilt 14.0° was significantly less than sitting 33.9° (p < 0.0001).
UNASSIGNED: There are key differences between standing and sitting postures, which could lead to undue stress on surgical implants and poor outcomes, especially for non-ambulatory populations. There is a need for more studies reporting sitting and standing radiographic measures in different postures and spinal conditions.

摘要：
■矢状失衡可由各种病因引起，并且是脊柱畸形的最重要指标之一。矢状平衡可以通过基于几种影像学检查的手术干预来恢复。这项研究的目的是回顾坐姿的正常参数，这一点还没有得到很好的理解，可能对非卧床患者产生重大影响。
■根据PRISMA指南进行了系统评价。使用R软件，使用随机效应模型和使用非配对t检验的显著性检验计算影像学检查结果的加权均值和95%置信区间.
■10篇文章，共有1066名受试者报道了坐姿和站立姿势无脊柱畸形的受试者的影像学测量。在健康的个体中，站立矢状垂直轴-16.8°明显小于坐28.4°（p<0.0001），而站立的腰椎前凸43.3°明显大于坐21.3°（p<0.0001）。胸椎后凸在两组之间没有显着差异（p=0.368）。站立骶骨倾斜34.3°显著大于坐19.5°(p<0.0001),站立骨盆倾斜14.0°显著小于坐33.9°(p<0.0001)。
■站立和坐着的姿势有关键的区别，这可能会导致对外科植入物的过度压力和不良结果，特别是对于非门诊人群。需要更多的研究报告不同姿势和脊柱状况下的坐姿和站立放射学测量。
