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。
Objective To investigate the incidence and clinical value of posterior circumferential bridge. Methods From 2005-09-2006-04, 795 cervical spine examinations were performed in our hospital, including 402 males and 393 females, aged 8-85 years old. All of them had posterior cervical X-ray and oblique CR films. According to Clinical symptoms (clinical group, 527 cases), no clinical symptoms (control group, trauma, physical examination, 268 cases) were divided into groups, the incidence of posterior annular bridge, clinical manifestations and the relationship between the posterior bridge. Results Among the 795 cases, 65 cases were posterior bridge, accounting for 8.2%, including 34 males (34/65) males and 31 females (31/65), 32 complete grafts (32/65), incomplete 33 cases (33/65) (P> 0.05), aged 18 to 82 years, mean 50 years. In the control group, 18 cases (18/268) of the posterior bridge were found in the control group; 47 cases (47/527) of the posterior bridge were found in the clinical group (P> 0.05). Conclusions The incidence of posterior annular bridge in this group was 8.2%. There was no significant difference in the incidence of posterior annular bridge between the posterior group and the presence or absence of clinical symptoms.
