Evaluation of reductive method of lower cervical bilateral facet dislocations / 中国矫形外科杂志

ABSTRACT

[Objective]To discuss the reductive method and clinical result of lower cervical bilateral facet dislocation.[Method]Totally 22 cases with lower cervical bilateral facet dislocation were treated from 2000 to 2006.According to resecting the injuried disc annulus pre-reduction or not,the patients were divided to 2 groups.The variation of neurological fauction level were classified according to ASIA grade system.Among 13 cases examined by MRI,There were disc herniated in 9 cases(69%).[Result]The average time of follow-up was 18 months.Neurological symptom became more severe in 1 cases which injured disc annulus weren't resected in-reduction and in 3 cases which injured disc weren't resected post-reduction.ASIA grade deteriorated 1 case upgraded from C to A,1 case upgraded from C to B,2 case upgraded C to D.But no one occurred in another group.[Conclusion]A lot of lower cervical bilateral facet dislocations have associated disc herniations.If injured disc isn't resected,the neurological symptom may become more severe.Resection injured disc,reduction,bone grafting can be settled in one time,in order to avoid secondary spine cord injury.
