Treatment of old dislocations of the lower cervical spine

Abstract

We treated surgically 12 patients with an old dislocation of the lower cervical spine. The time from injury to presentation averaged 3.5 (range 1.5-12) months, and the majority of the dislocations were between C4-5. Treatment started with 1 week of skull traction. If this resulted in reduction the area was stabilised by anterior fusion with plate fixation. If reduction by traction did not succeed a posterior partial facetectomy was performed. If this allowed reduction it was followed by a posterior fusion with plate fixation. If reduction was not achieved the traction was continued for a further week and then followed by anterior discectomy and fusion with plate fixation. The average follow-up was 34 (range 12-54) months, and all patients developed bone fusion and showed neurological improvement.
