摘要

Background: Cervical spine injuries are common as a result of a growing number of high energy accidents. The subaxial Injury Classification System and Severity Score (SLICS) suggest that a unilateral or bilateral facet dislocation must be managed surgically, even in the absence of SCI (Level of Evidence III). The surgical approaches could be anterior, posterior or combined anterior and posterior approaches. Methods: 20 patients, 12 males and 8 females, with age ranged from 20 to 45 years with lower cervical spine locked facet treated operatively by anterior or posterior spinal instrumentation after trial of closed reduction by skull traction. Results: In this series, satisfactory closed reduction was achieved in 15 patients with percentage 75% and fixed anteriorly, but 5 patients with percentage 25% needed posterior approach for reduction. Regarding ASIA score all of the patients improved at least one level after surgery except 2 cases with preoperative score A: they didn’t improve. Mean preoperative pain score VAS was 7.7 (range from 5 to 9) and postoperative mean of VAS was 0.75 with range from 0 to 3 until final follow up. Conclusion: Anterior approach with discectomy and fusion is necessary;however, if the closed reduction failed, posterior open reduction is indicated with lateral mass fixation, combined approaches can be indicated in specific cases such as increase of the kyphotic angle post anterior approach or when an osteotomy may be required to restore cervical alignment and neural decompression.
