在脊柱疾病的情况下，姿势评估的相关性已被报道。本研究探讨了在自由站立位和测力板上使用双平面X射线三维重建来量化姿势的兴趣。将93例因脊柱疾病就诊的患者分为“3D畸形”、“矢状面失衡”和“轻度畸形”，并与23例无症状志愿者进行比较。重建时对重力线（GL）进行配准，得到了外耳道中心（CAM）T1、T4、T9、L3、S1和髋轴（HA）相对于GL的横向位置。CAM和L3的横突位置是区分患者和志愿者的相关参数。连接CAM与HA的轴的倾斜度与CAM与GL的位置相关（患者r = 0.92）。总之，在3D中观察GL的姿势提供了临床相关信息。CAM-HA倾斜度可改善无测力板的姿势评估。
Relevance of posture assessment has been reported in case of spine disorders. This study explores the interest in quantifying posture using 3D reconstruction from biplanar X-rays in free standing position and a force plate. 93 patients consulting for spine disorders were divided ('3D deformity', 'sagittal imbalance' and 'mild deformity') and compared with 23 asymptomatic volunteers. Registration of the gravity line (GL) in reconstruction yielded transversal position of the center of acoustic meati (CAM) T1, T4, T9, L3, S1 and hip axis (HA) with regard to GL. Transversal position of CAM and L3 appeared as relevant parameters to discriminate patients from volunteers. Sagittal inclination of the axis linking the CAM to HA was correlated with position of the CAM to GL (r = 0.92 for patients). In conclusion, observing posture in 3D with regard to GL provides clinical relevant information. CAM-HA inclination may improve postural evaluation without force plate.
