To investigate the gravitational effect on coronal curvature and vertebral rotation using 3-D ultrasound in patients with adolescent idiopathic scoliosis (AIS).
Sixteen female patients with AIS were recruited and examined using a 3-D ultrasound unit incorporated with SonixGPS system (Ultrasonix Medical Corporation, Canada). Ultrasound scanning was performed continuously along the coronal plane from C7 to S1, with a standing and a supine position, respectively. Coronal curvature and vertebral rotation were measured using the center of laminae (COL) method. Multivariate linear regression models were established to determine factors associated with changes of lateral curvature and vertebral rotation in different posture positions. The correlations of measurements between standing and supine were tested using Pearson correlation analyses.
Changes of coronal curvature and vertebral rotation from a supine to a standing posture were within 1.9°-11.7° and 0.0°-5.9°, respectively. The changes increased with the severity of AIS. The 3-D ultrasound measurements of lateral curvature and vertebral rotation were highly correlated.
3-D ultrasound can reveal changes of coronal curvature and vertebral rotation from a supine to a standing posture in patients with AIS, which increase with the severity of AIS. Further studies in large samples are warranted.
采用三维超声研究青少年特发性脊柱侧凸（AIS）患者中重力对冠状面弯曲和椎体旋转的影响。
招募16例AIS女性患者，使用配备SonixGPS系统（加拿大Ultrasonix医疗公司）的三维超声设备进行检查。分别在站立位和仰卧位沿冠状面从C7至S1连续进行超声扫描。采用椎板中心（COL）法测量冠状面弯曲和椎体旋转。建立多变量线性回归模型以确定不同体位下与侧方弯曲和椎体旋转变化相关的因素。采用Pearson相关分析检验站立位和仰卧位测量值之间的相关性。
从仰卧位到站立位，冠状面弯曲和椎体旋转的变化分别在1.9° - 11.7°和0.0° - 5.9°之间。这些变化随AIS严重程度增加而增大。侧方弯曲和椎体旋转的三维超声测量值高度相关。
三维超声可显示AIS患者从仰卧位到站立位时冠状面弯曲和椎体旋转的变化，且这些变化随AIS严重程度增加而增大。有必要进行大样本的进一步研究。
