New reduction technique for the treatment of unilateral locked facet joints of the lower cervical spine : A retrospective analysis of 12 cases.

BACKGROUND

Closed reduction of bilateral locked facet joints of the lower cervical spine is possible, but reduction of unilateral locked facet joints of the lower cervical spine (ULFJLCS) is challenging. We explored a new, simple, safe, and effective closed reduction method for the treatment of ULFJLCS.

METHODS

A retrospective analysis was done on 12 consecutive cases with traumatic ULFJLCS that underwent closed reduction by Z‑shape elevating-pulling reduction through a halo-vest. After reduction, only anterior cervical decompression and internal fixation were performed. The success of reduction and nerve function was assessed, and follow-up data analyzed.

RESULTS

All patients using our new reduction technique underwent successful closed reduction; the shortest time of reduction was 40 min and the longest 110 (mean, 65) min. No aggravation of neurological damage was observed, nor were other complications. All patients were followed-up from 28 to 72 (mean, 44) months after surgery. The improvement in Frankel's score (on average) was two levels in most patients.

CONCLUSION

These data demonstrate that our new reduction technique is a simple, safe, and effective treatment for ULFJLCS.
