ObjectiveTraumatic high-grade cervical spinal dislocations are rare injuries, generally associated with severe neurological compromise. In particular, cervical spondyloptosis (>100% subluxation) is rarely reported. The object of our study is to present a case series describing presentation, management, and outcome in traumatic high-grade cervical spinal dislocations.MethodsRetrospective analysis was performed involving two level 1 trauma centers. Patients with a high-grade traumatic cervical subluxation were selected from a database, and these patients were admitted between August 2007 and July 2011.ResultsFifteen patients were identified; three had spondyloptosis. The admission American Spinal Injury Association Impairment Scale (AIS) grade varied (A = 9; B = 2; C = 1; D = 2; E = 1). Fourteen patients underwent attempted closed reduction with six (43%) failing closed reduction. High-dose methylprednisolone was administered in nine patients (60%). All patients underwent surgical stabilization: three underwent anterior only, three underwent posterior only, and nine underwent a combined anterior-posterior approach. Postoperatively, one patient improved two AIS grades, three improved one AIS grade, nine maintained their preoperative score, and two patients worsened.ConclusionsIn this series, 26.7% of patients had improvement in their AIS grade postoperatively, and the majority of patients (60%) maintained their preoperative AIS grade. In 57% of patients placed in traction, reduction was possible. Likely due to the severity of these injuries, there was a high incidence of complications. However, review of patient outcomes reveals that these patients can have improvement of neurological function. We recommend aggressive reduction and surgical stabilization. Our preference is either a combined anterior-posterior approach or a posterior-only approach.Copyright © 2014 Elsevier Inc. All rights reserved.
