PURPOSE
To document values for parameters of global spinal balance in asymptomatic children and adolescents.
METHODS
Multicenter prospective study of normal sagittal global spinal balance in Caucasian children and adolescents. Spinosacral angle (SSA), spinal tilt (ST), and C7 translation ratio were evaluated in 646 asymptomatic children and adolescents (276 males and 370 females).
RESULTS
Mean and standard deviation for SSA, ST, and C7 translation ratio were, respectively 132.1° ± 8.3°, 93.2° ± 4.6° and -0.7 ± 8.3. Mean ± 2 standard deviations were, respectively 116°-149° for SSA and 84°-102° for ST. C7 plumbline was behind the HA (hip axis) in 78 % of subjects. Correlations between global balance and age were small (-0.17 ≤ r ≤ 0.19).
CONCLUSION
Asymptomatic children and adolescents tend to stand with a stable global balance, and 95 % have an SSA and ST between 116° and 149° and 85°-102°, respectively. C7 plumbline in front of the HA is not necessarily associated with a spinal pathology.
目的
记录无症状儿童和青少年的整体脊柱平衡参数值。
方法
对高加索儿童和青少年的正常矢状面整体脊柱平衡进行多中心前瞻性研究。对646名无症状儿童和青少年（276名男性和370名女性）评估了脊柱骶骨角（SSA）、脊柱倾斜度（ST）和C7平移比率。
结果
SSA、ST和C7平移比率的平均值及标准差分别为132.1°±8.3°、93.2°±4.6°和 -0.7±8.3。SSA的平均值±2个标准差分别为116° - 149°，ST为84° - 102°。78%的受试者中C7铅垂线位于髋关节轴（HA）后方。整体平衡与年龄之间的相关性较小（-0.17≤r≤0.19）。
结论
无症状儿童和青少年倾向于以稳定的整体平衡站立，95%的儿童和青少年的SSA和ST分别在116°至149°和85° - 102°之间。HA前方的C7铅垂线不一定与脊柱病变相关。
