Debrunner脊柱后凸测量器是检测和评价胸椎后凸的公认工具。本前瞻性研究旨在创建一个数学公式，仅使用后凸测量仪，以高度近似的方式提供胸椎后凸（T4-T12）的X线摄影角度。采用简单和多元线性回归分析，对90名连续筛选的青少年（44名男性和46名女性）的几个临床（后凸计值、年龄和性别）和影像学（Cobb角[T4-T12]）参数进行相关性分析。使用Debrunner椎体后凸计测量的可靠性较高。后凸计值与X线测量的胸椎Cobb角密切相关（简单线性回归分析;概率范围，0.0026至0.0002）。年龄和性别与胸椎后凸无相关性。使用后凸测量仪和数学公式预测的后凸角度为44.66度+/- 2.68度（范围27 - 62度），而真实的X线片后凸角度为47.5度+/- 3.53度（范围24 - 70度）。后凸测量仪和公式在测量小于50 °的后凸时更为可靠和准确。在这项研究中，作者构建了一个数学公式，仅使用Debrunner后凸测量器，偏差小于3度，即可准确提供青少年的X线片T4-T12后凸角。作者建议所有从事脊柱后凸筛查项目的医生结合最近构建的简单数学公式使用脊柱后凸测量仪。这种方法将减少学校筛查项目的成本，过度诊断和青少年不必要的辐射暴露。
The Debrunner kyphometer is an accepted tool for detecting and evaluating thoracic kyphosis. This prospective study was conducted to create a mathematical formula that provides, with high approximation, the roentgenographic angle of thoracic kyphosis (T4-T12) using only the kyphometer. Several clinical (kyphometer value, age, and sex) and radiographic (Cobb angle [T4-T12]) parameters from 90 consecutively screened adolescents (44 male and 46 female) were correlated using simple and multiple linear regression analyses. The reliability of measurement using the Debrunner kyphometer was high. The kyphometer value was strongly correlated with the roentgenographically measured thoracic Cobb angle (simple linear regression analysis; probability range, 0.0026 to 0.0002). There was no correlation between age or sex and thoracic kyphosis The predicted kyphosis angle using the kyphometer and the mathematic formula was 44.66 degrees +/- 2.68 degrees, (range 27 to 62 degrees), and the real roentgenographic kyphosis angle was 47.5 degrees +/- 3.53 degrees, (range, 24 to 70 degrees). The kyphometer and formula were more reliable and accurate when kyphosis less than 50 degrees was measured. In this study, the authors constructed a mathematical formula that accurately provides the roentgenographic T4-T12 hyphosis angle in adolescents using only the Debrunner kyphometer with a deviation of less than 3 degrees. The authors recommend that all physicians engaged in kyphosis screening programs use the kyphometer combined with the recently constructed simple mathematic formula. This method will reduce the cost of school screening programs, overdiagnoses, and unnecessary exposure of adolescents to irradiation.
