| 摘要: |
| 目的 探讨基于棘突体表投射空间三维位置的脊柱形态测量仪在不同脊柱侧凸形态测量中的应用。方法 纳入32例青少年特发性脊柱侧凸（AIS）患者，应用空间姿态传感器感知棘突位置变化的脊柱形态测量仪，测量患者背部体表投射位置的棘突连线成角（SPA）。采用线性回归模型构建SPA与全脊柱正侧位X线片所测量Cobb角的数量关系。根据Lenke分型进行亚组分析，探究在不同侧凸形态中SPA与Cobb角的数量关系。结果 32例AIS患者中男11例、女21例，年龄为（13.94±0.84）岁；Lenke Ⅰ型20例，Lenke Ⅴ型12例；8例患者主弯累及T5~T11，4例累及T5~T12，1例累及T6~T11，7例累及T6~T12，4例累及T11~L3，8例累及T12~L4。线性回归分析发现，在AIS患者中Cobb角与SPA呈线性关系，两者之间线性回归方程为：Cobb角=1.128×SPA+3.724。进一步亚组分析发现，在Lenke Ⅰ型AIS患者中Cobb角和SPA同样存在线性关系，两者之间线性回归方程为：Cobb角=1.128×SPA+3.303。结论 基于棘突体表投射空间三维位置的脊柱形态测量仪能够用于脊柱胸段侧凸的形态测量，棘突在体表的空间投射位置是脊柱形态测量的有效解剖参考标志。 |

| Abstract: |
| Objective To apply spine morphology measuring instrument based on three-dimensional projection position of the spinous process on the body surface in different types of scoliosis. Methods Thirty-two adolescent idiopathic scoliosis (AIS) patients were enrolled in this study. The spine morphology measuring instrument based on space posture sensor was used to measure the spinous process angle (SPA) of the projection position on the patient back surface. Then linear regression model was used to establish the quantitative relationship between SPA and Cobb angle measured by full-spine X-ray film. Based on the Lenke classification, subgroup analysis was conducted to further explore the quantitative relationship between SPA and Cobb angle in different types of scoliosis. Results The 32 AIS patients included 11 males and 21 females, with an average age of (13.94±0.84) years; 20 cases were Lenke typeⅠ and 12 cases were Lenke typeⅤ; eight cases had main curvature of T5-T11, four cases of T5-T12, one case of T6-T11, seven cases of T6-T12, four cases of T11-L3, and eight cases of T12-L4. Linear regression analysis found that the Cobb angle had a linear relationship with the SPA in AIS patients:Cobb angle=1.128×SPA+3.724. Further subgroup analysis showed that for Lenke typeⅠ AIS patients, the quantitative relationship was:Cobb angle=1.128×SPA+3.303. Conclusion The spine morphology measuring instrument based on three-dimensional projection position of the spinous process on the body surface can be initially applied to measure the spine morphology of the thoracic scoliosis. The spatial projection position of the spinous process on the body surface is an effective anatomical reference marker for spinal morphometry. |
