    摘 要:目的 探讨骨质疏松合并颈椎病时颈椎影像学及骨密度变化之间的关系. 方法 分3组，正常组20例，平均年龄23岁;颈椎间盘突出症组(颈椎组)18例，平均年龄43岁，桡骨骨密度正常，行颈椎前路手术;骨质疏松合并颈椎管狭窄症组(疏松组)25例，平均年龄59岁，桡骨骨密度低于正常，行颈椎后路手术.所有病例测量颈椎侧位C3 -C6 的椎管、椎体矢状径比，椎体变形指数，C4 -C6 骨密度.数据进行统计学处理. 结果 与正常组相比，颈椎组患者仅在C5 ，C6 椎体出现轻度椎管狭窄，椎体变形，骨密度无明显变化;疏松组则是颈椎广泛椎管狭窄，椎体变形，骨密度升高，三值之间有较明显的相关性. 结论 颈椎骨质疏松可能是颈椎开始退变进而发展为颈椎病的始动因素之一.C5 ，C6 椎体最早发生椎体变形，椎管狭窄，以后逐渐扩大至其他椎体.椎体周围骨增生使椎体骨密度升高.
