A retrospective survey of thoracic spinal curvature compared postmortem radiographs with recent clinical films in 22 cases.
This study was performed to determine whether spinal curvature measured from postmortem radiographs is a valid measure of curvature in vivo.
Little quantitative data have been cited on whether sagittal plane thoracic spinal curve characteristics change after death.
Thoracic kyphosis was measured using the Cobb method and the mean radius of curvature from computer-assisted digitizing of the vertebral contour. Thoracic segments visualized on the chest films were referenced to the postmortem radiograph.
The in vivo and in vitro measurements strongly correlated (Cobb angle r = 0.95, curvature r = 0.78). Trends decreased slightly in Cobb angle (1.3%, -2.6%) and increased slightly in curvature (10.7 mm, 4.1%). Differences were not significant, however, supporting the use of spinal curvature analysis with postmortem radiographs.
一项回顾性调查，对22例病例的胸椎后凸进行了比较，将死后X光片与近期临床X光片进行对照。
本研究旨在确定从死后X光片测量的脊柱曲度是否是活体曲度的有效测量指标。
关于矢状面胸椎曲线特征在死后是否发生变化，很少有定量数据被引用。
使用Cobb法测量胸椎后凸，并通过计算机辅助数字化椎体轮廓来测量平均曲度半径。胸部X光片上可见的胸段与死后X光片进行对照。
活体测量和体外测量高度相关（Cobb角r = 0.95，曲度r = 0.78）。Cobb角有轻微下降趋势（1.3%，-2.6%），曲度有轻微上升趋势（10.7毫米，4.1%）。然而，差异不显著，这支持了在死后X光片上进行脊柱曲度分析。
