摘要
目的:研究成人枢椎解剖学变异的发生情况,为临床诊治提供解剖形态学基础。方法:对100例成人干燥枢椎骨骼标本的解剖学变异,如齿突偏歪、棘突轴线偏歪、棘突分叉情况等指标进行观测并测量横突尖至下关节面前缘距离。结果:100例枢椎标本齿突偏歪者14例(14%)、棘突轴线偏歪者3例(3%)、棘突分叉者96例(96%),其中棘突分叉左右两侧相等者56例(56%)、左侧长于右侧者21例(21%)、右侧长于左侧者19例(19%),横突尖至下关节面距离,左侧(17.39±2.53)mm、右侧(17.35±2.51)mm。结论:枢椎的解剖学变异较为常见,临床触诊及X线检查时应考虑到其解剖学变异及特点等因素。
Objective： To study anatomic variations of axis and probe its significance in clinical diagnosis and treatment. Methods： The anatomic variations of 100 dry axes, including the skew dens, the skew spinous process and the bifid spinous process were observed and measured. In addition, the distances between the tip of transverse process and the inferior articular facet of axis were measured. Results： For all of the 100 axes, the skew dens appeared in 14 samples （14 %）, the skew spinous process in 3 samples （3 %）, and the bifid spinous process in 96 samples（96%）, with the same length in both bifid spinous process of 56 samples（56 % ）, the long left hifid spinous process of 21samples （21% ）, and the long right ones of 19 samples （19%）. The distance between the tip of transverse process and the inferior articular facet at the left side was （17.39±2.53 mm）, at the right side （17.35±2.5 lmm）. Conclusions： The anatomic variations of axis are relatively common, and should be considered during clinical palpation and X-ray examination.
