腰椎管诸壁与其面积间的逐步回归分析及其临床意义

Stepwise Regression of Spinal Canal's Wall and Area and Its Significance

在经椎弓根上1/3弓根上缘的CT扫描图像上,对111个(男78个,女33个)正常腰椎的椎管及相关结构进行了14项指标的测量,经逐步回归分析发现椎管横径及矢径与椎管面积呈显著正相关,为腰椎管狭窄的诊断提供了一些客观的形态学依据。

The vertebral canals and structures involved were measured in 111 normal cases (male 78, female 73) for 14 indexes in the light of CT scanning pictures of the vertebral pedicle's upper border and the 1/3 section. The stepwise transverse and sagittal diameters are positively related to its area. Morphologically, such information may, in an objective manner, be useful in the diagnosis of spinal canal stenosis.
