类风湿性关节炎(rheumatoid arthritis,RA)对全身多处关节均会产生影响,并可引起严重畸形和功能损害,颈推亦常为RA所侵犯。本研究对1992年至2008年取自美国全国住院病历数据库的合并RA且行颈惟融合手札的患者进行回顾性研究,比较合并RA患者与正常人群颈惟融合手木术后的不同发展趋势。共包含36 200例寰枢推融合病例,其中4 9丨8例(13.3%)合并RA?在研究的总体样本中.行寰怄推融合手术患者数逐年增加(尸<0.01),而合并RA的手术患者数则显著下降(尸<0.05);普通人群寰怄推融合率逐年上升(P<0.0丨〉,而RA患者融合率则显著下降(P<0.01)。
Rheumatoid arthritis (RA) affects multiple parts of the body and causes severe deformities and impaired function. Cervical pushing is also often infused with RA. This study retrospectively studied patients with RA combined with hand-necked neck radiographs collected from the National Inpatient Case History database from 1992 to 2008 and compared the differences between the RA patients and the normal controls. A total of 36 200 cases of atlanto-axial fusion were included, among which 49 cases (13.3%) with RA were in the overall study sample. The number of patients who underwent atlantoaxial fusion increased year by year (P <0.01) (P <0.05). The fusion rate of the general population increased year by year (P <0.0), while the fusion rate of RA patients decreased significantly (P <0.01).
