摘　　要：目的探讨颈椎阻滞椎的X线表现及特征。方法回顾性分析125例颈椎阻滞椎X线资料,男性45例,女性80例,年龄24~75岁,平均年龄41.9岁,男女比例为1:1.77。分析其阻滞椎的发生节数、融合部位、骨赘发生、颈椎前凸曲度以及上、下椎间隙等情况。结果本组病例中阻滞椎累及2个椎体100例,累及3个椎体5例,累及4个椎体17例,累及5个椎体3例。单节段阻滞椎以C2~3最多,共43例(43%);其次是C3~4,共16例(16%)。融合部位:椎体及附件的同时融合82例(65.6%),单纯椎体融合28例(22.4%)。颈椎曲度变直或反张36例(28.8%)。椎体前/后缘骨赘110例(88%);上椎间隙狭窄7例(5.6%);下椎间隙狭窄15例(11.7%);棘突融合52例(41.6%);前纵韧带钙化19例(15.2%);项韧带钙化17例(13.6%);颅底凹陷症15例(12%)。结论颈椎阻滞椎常表现为单节段的融合,椎体及附件的同时融合比单纯椎体融合多见。阻滞椎常伴有邻近节段的退行性改变及颅底凹陷。Objective To investigate the X-ray performance and characteristics of cervical vertebral block.MethodsThe X-ray data of 125 patients with cervical vertebral block were retrospectively analyzed,including 45 males and 80 females,with an average age of 41.9 years old(male to female ratio was 1:1.77),ranging from 24 to 75.The number of nodes,fusion sites,the occurrence of callus,cervical lordosis curvature,and upper and lower vertebral space were analyzed.ResultsCervical vertebrae block was involved 2 vertebrae in 100 cases,3 vertebrae in 5 cases,4 vertebrae in 17 cases,and 5 vertebrae in 3 cases.The single-segment fusion block was the most common in the C2~3segment(43 cases,43%),followed by the C3~4segment(16 cases,16%).Thirty-six cases(28.8%)of cervical curvature were straightened/anti-arched.Among the X-ray findings,vertebral anterior/posterior osteophytein was found in 110 cases(88%);stenosis in the upper disc space was found in 7 cases(5.6%);stenosis in the lower disc space was found in 15 cases(11.7%);spinous process fusion was found in 52 cases(41.6%);calcification of the anterior longitudinal ligament was found in 19 cases(15.2%);ligament calcification was found in 17 cases(13.6%);skull base depression was found in 15 cases(12%).ConclusionsCervical vertebral block often shows singlesegment fusion.Simultaneous fusion of the vertebral body and attachment is more common than the vertebral body fusion alone.Cervical vertebral block is often accompanied by adjacent segment degeneration and basilar invagination.
