摘　　要：背景为评估脊柱骨盆矢状位序列平衡,脊柱骨盆影像学参数近年来成为研究热点,骶骨形态参数作为一种新型参数体系而备受瞩目。关联因素的研究对于提高骶骨形态参数的临床应用价值有着重大意义。目的探讨年龄、体位、性别因素对骶骨形态参数的影响。方法选取2013年1月-2020年12月于解放军总医院第一医学中心体检人群的脊柱全长片和脊柱核磁影像资料,筛选并测量120例未成年人(站立位)、131例成年人(站立位)和88例成年人(仰卧位)的骶骨形态参数(S1-2T、SK、α、β和θ)和脊柱骨盆参数(LL和PI)。制作PI、S1-2T、SK、α、β、θ与年龄散点图。比较站立位未成年人与成年人骶骨形态参数差异,并对两组S1-2T、SK、α、β、θ、PI与PI、LL行Pearson相关性分析;比较成年人站立位与仰卧位骶骨形态参数差异,并对两组S1-2T、SK、α、β、θ与LL进行相关性分析并求得θ与LL线性回归方程;控制体位因素变量,比较成年男性与女性骶骨形态参数差异。结果SK、α、PI随年龄增加而增加,至成年后平稳,SK和α增加约10°,PI增加约20°;S1-2T、θ、β无明显变化;未成年人与成年人骶骨形态参数差异无统计学意义(P>0.05);未成年人PI与LL无相关性(P>0.05),而SK、α、θ与LL有相关性(P<0.05)。不同体位下成年人S1-2T、SK、LL差异有统计学意义(P<0.05),而α、β、θ差异无统计学意义(P>0.05);站立位和仰卧位时,θ与LL相关性最强,相关系数分别为-0.520、-0.530;仰卧位:LL=-0.3398×θ+63.12(r=-0.530),站立位:LL=-0.4509×θ+79.45(r=-0.520);同一体位,成年男性与女性骶骨形态参数差异无统计学意义(P>0.05);成年男性由站立位转为仰卧位,S1-2T差异有统计学意义(P<0.05),成年女性由站立位转为仰卧位,S1-2T、SK、α差异有统计学意义(P<0.05)。结论年龄对于骶骨形态参数影响较小,该参数在未成年人中相比PI与LL相关性更强;α、β、θ不受体位�Background In order to evaluate the sagittal balance of the spine and pelvis,spinal-pelvic imaging parameters have become a research hotspot in recent years,and sacrum morphologic parameters have attracted much attention as a new parameter system.The study of related factors is of great significance to improve the clinical application value of sacrum morphological parameters.Objective To investigate the influence of age,body position,and sex on sacrum morphological parameters.Methods Whole spine radiographs and spine MRI data were collected from the individuals who underwent physical examination in our hospital from January 2013 to December 2020,and sacrum morphological parameters(S1-2T,SK,α,β,andθ)and spinal-pelvic parameters(lumbar lordosis[LL]and pelvic incidence[PI])were measured for 120 juveniles(in the standing position),131 adults(in the standing position),and 88 adults(in the supine position).Scatter plots of PI,S1-2T,SK,α,β,θ,and age were generated.Sacrum morphological parameters in the standing position were compared between the juveniles and the adults,and Pearson correlation analysis was performed for S1-2T,SK,α,β,θ,PI,and LL in both groups;sacrum morphological parameters in adults were compared between the standing position and the supine position,correlation analysis was performed for S1-2T,SK,α,β,θ,and LL,and the linear regression equations ofθand LL were obtained.After control for the variable of body position,sacrum morphological parameters were compared between adult male and female individuals.Results SK,α,and PI increased with age and remained stable after an individual became an adult,with SK andαincreasing by about 10°and PI increasing by about 20°,while there were no significant changes in S1-2T,θ,andβ.There was no significant difference in sacrum morphological parameters between the juveniles and the adults(P>0.05).There was no correlation between PI and LL in the juveniles(P>0.05),but there was a correlation between SK,α,θand LL(P<0.05).There were significant differen
