Accurate noninvasive measurements of spinal curvature are crucial in planning treatment and assessing curve progression in adolescent idiopathic scoliosis. An inter-rater agreement trial and an intrarater agreement trial were undertaken to estimate the reliability of axial rotation measurement using the Scoliometer (Orthopedic Systems, Inc., Haywood, California). In the inter-rater trial, two orthopedic surgeons and two orthopedic surgery residents independently measured the thoracic and lumbar axial rotations of 22 patients with idiopathic scoliosis using the Scoliometer. In the intrarater, trial a single orthopedic surgeon measured the thoracic and lumbar axial rotations of 25 patients on four separate occasions with the Scoliometer. Inter-rater agreement using the Scoliometer to estimate the magnitude of the hump (in centimeters) in the thoracic and lumbar regions was poor (intraclass correlation coefficient, Rho = 0.57 and Rho = 0.76 for the thoracic and lumbar regions, respectively). Inter-rater agreement using the Scoliometer to estimate the degree of axial trunk rotation was better (Rho = 0.81 and Rho = 0.82 for the thoracic and lumbar regions, respectively). Intrarater agreement using this device to estimate the magnitude of the hump (in centimeters) in the thoracic and lumbar regions was good (Rho = 0.90 and Rho = 0.84 for the thoracic and lumbar regions, respectively). Intrarater agreement using the Scoliometer to estimate the degrees of curvature was outstanding (Rho = 0.995 and Rho = 0.998 for the thoracic and lumbar regions, respectively). These results indicate that the Scoliometer can be a reliable noninvasive method for repetitively assessing spinal axial rotation when used by a single trained observer.
准确的脊柱侧弯无创测量对于青少年特发性脊柱侧弯的治疗规划和评估侧弯进展至关重要。进行了一项评分者间一致性试验和一项评分者内一致性试验，以评估使用脊柱侧弯测量仪（骨科系统公司，加利福尼亚州海伍德）进行轴向旋转测量的可靠性。在评分者间试验中，两名骨科外科医生和两名骨科外科住院医师使用脊柱侧弯测量仪独立测量了22例特发性脊柱侧弯患者的胸段和腰段轴向旋转。在评分者内试验中，一名骨科外科医生使用脊柱侧弯测量仪在四个不同时间测量了25例患者的胸段和腰段轴向旋转。使用脊柱侧弯测量仪估计胸段和腰段驼峰大小（以厘米为单位）的评分者间一致性较差（胸段和腰段的组内相关系数，Rho分别为 = 0.57和Rho = 0.76）。使用脊柱侧弯测量仪估计躯干轴向旋转程度的评分者间一致性较好（胸段和腰段的Rho分别为 = 0.81和Rho = 0.82）。使用该设备估计胸段和腰段驼峰大小（以厘米为单位）的评分者内一致性良好（胸段和腰段的Rho分别为 = 0.90和Rho = 0.84）。使用脊柱侧弯测量仪估计弯曲度的评分者内一致性非常出色（胸段和腰段的Rho分别为 = 0.995和Rho = 0.998）。这些结果表明，当由一名经过培训的观察者使用时，脊柱侧弯测量仪可以作为一种可靠的无创方法来重复评估脊柱轴向旋转。
