A prospective analysis of the sagittal profile of 100 healthy young adult volunteers was carried out in order to evaluate the relationship between the shape of the pelvis and lumbar lordosis and to create a databank of the morphologic and positional parameters of the pelvis and spine in a normal healthy population. Inclusion criteria were as follows: no previous spinal surgery, no low back pain, no lower limb length inequality, no scoliotic deviation. For each subject, a 30 x 90-cm sagittal radiograph including spine, pelvis and proximal femurs in standing position on a force plate was performed. The global axis of gravity was determined with the force plate. Each radiograph was digitized using dedicated software. The spinal parameters registered were values for thoracic kyphosis and lumbar lordosis. The pelvic angles measured were: pelvic incidence, sacral slope and pelvic tilt. The global axis of gravity was on average 9 mm anterior of the center of the femoral heads. The anatomic parameter of pelvic incidence angle varied from 33 degrees to 85 degrees (mean: 51.7 degrees, SD: 11 degrees). The average lumbar lordosis was 46.5 degrees. The average thoracic kyphosis was 47 degrees. We found a statistical correlation between incidence angle and lumbar lordosis (r=0.69, P<0.001) and between sacral slope angle and lumbar lordosis (r=0.75, P<0.001). Spine and pelvis balance around the hip axis in order to position the gravity line over the femoral heads. We propose a scheme of sagittal balance of the standing human body.
对100名健康年轻成年志愿者的矢状面轮廓进行了前瞻性分析，以评估骨盆形状与腰椎前凸之间的关系，并建立正常健康人群骨盆和脊柱形态及位置参数的数据库。纳入标准如下：既往无脊柱手术史、无腰痛、双下肢无长度不等、无脊柱侧弯。对每位受试者，在测力板上站立位拍摄一张包括脊柱、骨盆和近端股骨的30×90厘米矢状位X线片。用测力板确定重力总轴。每张X线片使用专用软件进行数字化处理。记录的脊柱参数为胸椎后凸和腰椎前凸的值。测量的骨盆角度为：骨盆倾斜度、骶骨倾斜度和骨盆倾斜角。重力总轴平均位于股骨头中心前方9毫米处。骨盆倾斜角的解剖学参数在33度至85度之间变化（平均：51.7度，标准差：11度）。平均腰椎前凸为46.5度。平均胸椎后凸为47度。我们发现倾斜角与腰椎前凸之间存在统计学相关性（r=0.69，P<0.001），骶骨倾斜角与腰椎前凸之间也存在统计学相关性（r=0.75，P<0.001）。脊柱和骨盆围绕髋关节轴平衡，以便将重力线定位在股骨头上方。我们提出了一个站立人体矢状面平衡的方案。
