48例维吾尔族成人寰椎管率的X线测量及其临床意义

X-ray measurement of atlas canal diameter ratio of Xinjiang Uygur adults and its clinical significance

目的:探讨寰椎管矢状面直径及寰椎体矢状面直径 X线测量的临床意义。方法:选择 4 8例年龄 18～5 0岁的维吾尔族成人 ,在其颈椎侧位片上测出寰椎管矢状面直径及其相应椎体矢状面直径 ,并计算其比值 (寰椎管率 )。结果:男性寰椎管和寰椎体矢状面直径均大于女性 ,寰椎管率男性均小于女性。寰椎管、寰椎体与寰椎管矢状面直径男女性之间差异均有统计学意义 ( P <0 .0 5 )。 结论 :测量结果可为正常颈椎的 X线解剖学和临床放射学诊断提供依据 ,对于颈椎管狭窄的诊断具有重要的参考价值。

Objective: To discuss the clinical significance of X ray diameter both from vertebral canal and vertebral arch in the sagittal plane of atlas. Methods: randomly selected 48 Uygur adult profile X ray film of cervical vertebrae (from 18~50 years old) to measure the diameter of atlas's vertebral canal and vertebral arch, finally calculate the ratio of their diameters. Results: Both of the two diameters measured: male's diameter was larger than that of females. The vertebral canal ratio of male was smaller than that of female, there was statistic significance between male and female by significant test of the two samples (P<0.05). Conclusion: The results of the measurement can provide the diagnostic foundation of X ray anatomy and cilinical radiology and can provide important reference in diagnosis of the stenosis of cervical vertebral canal.
