Purpose
Reduction of cervical facet dislocation should be performed as soon as possible to depressurize neuron cells although some randomized control studies defined early reduction as over 24 h after trauma. The purpose of this study was to define the actual time limit for early reduction in patients with complete motor paralysis.
Methods
Cervical spine dislocation patients with complete motor paralysis admitted between April 2007 and December 2014 were analyzed as retrospective cohort study. We separated the patients into three groups according to the number of hours lapsed between the trauma and reduction, within 4 h (very early group), >4–6 h (early group), and >6 h (delayed group). We compared the neurological outcomes, patient injury patterns, the arrival time at the hospital, and the injury severity score (ISS).
Results
Of 30 patients who enrolled, 8 (27%) were recovered to American Spinal Injury Association Impairment Scale Grades C-E. The delayed group had poorer neurological outcomes than the very early group and early group, although no significant differences were noted in the recovery rate between the very early group and early groups. The injury pattern, arrival time, and ISS were not found to be associated with the neurological outcome.
Conclusion
Our data suggest that early (<6 h) reduction of cervical spine dislocation is associated with favorable neurological outcome as compared with those performed after 6 h.
