【摘要】 目的探讨环椎后桥的发生率及其临床价值。方法取2005-09—2006-04来我院行颈椎检查者795例,其中男402例,女393例,年龄8~85岁,均有颈椎X线正侧位、斜位CR片,按照有临床症状(临床组,527例)、无临床症状(对照组,外伤、查体,268例)分组,分析环椎后桥的发生率、临床表现与环椎后桥的关系。结果795例中,环椎后桥65例,占8.2%,其中男34例(34/65),女31例(31/65);完全型骨桥32例(32/65),不完全型33例(33/65)(P>0.05),年龄18~82岁,平均50岁。对照组发现环椎后桥18例(18/268);临床组发现环椎后桥47例(47/527)(P>0.05)。结论环椎后桥在本组中的发生率为8.2%,环椎后桥发生率与有无临床症状无显著性差异。更多还原

【Abstract】 Objective To study the incidence and clinical significance of the posterior bridge of the atlas(PBOA).Methods 795 cases (402 men,393 women,8～85 years in age)were collected from Sep.2005 to Apr. 2006 in our hospital,they all had cervical spine CR films including PA,lateral and oblique projection.All cases were divided into two groups according to the clinical symptom:clinical group (with clinical symptom,n=527),comparative group(without clinical symptom,n=268).The incidence and the relation between the clinical manifestations and PBOA were analysed.Results Of 795 cases,there were 65 cases(8.2%)with PBOA,including 34 men and 31 women(age ranged from 18 to 82 years,mean 50 years).The complete posterior bridge was found in 32 cases(32/65),and incomplete posterior bridge in 33 cases(33/65).18 cases of PBOA (18/268) were showed in comparative group,and 47 cases(47/527) in clinical group(P>0.05).Conclusion The incidence of PBOA is 8.2 % in this group.There is no significant difference between the clinical group and comparative group.更多还原
