Thirty-five untreated patients with scoliosis were studied by Cobb radiography and back-surface photogrammetry on each of at least two clinic visits. Also, the maximum vertebral axial rotation was measured. Each pair of patient visits was classified as showing either a progression, improvement, or no change in the scoliosis using a threshold of 5 degrees change in the Cobb angle. The computer Cobb measurement was the most precise measurement, and the back-surface measurements were the least precise. The Cobb measurement of scoliosis is the most precise for detecting small changes, but can be improved by a computerized analysis of digitized radiographs.
对35例未经治疗的脊柱侧弯患者至少进行了两次门诊就诊,每次就诊时均采用Cobb X线摄影和背部表面摄影测量法进行研究。此外,还测量了最大椎体轴向旋转度。根据Cobb角变化5度的阈值,将每对患者就诊情况分类为脊柱侧弯进展、改善或无变化。计算机Cobb测量是最精确的测量方法,而背部表面测量是最不精确的。Cobb测量脊柱侧弯对于检测微小变化最为精确,但通过对数字化X线片进行计算机分析可进一步改进。
