Abstract
The purpose of this retrospective study was to examine specific patient variables and fracture morphologies to further elucidate the predictors of successful halo-vest treatment for cervical spine fractures (C3-C7). Eighty-seven cases of acute cervical spine injuries treated with halo-vest management were reviewed to assess initial injury features and radiographie outcomes by measuring (a) subluxation and direction, (b) angulation, (c) facet abnormalities, and (d) vertebral body fracture patterns on plain radiographs and computed tomography scans. The cases were divided into three groups: facet subluxa-tions with fractures, facet subluxation without fractures, and fractures with no subluxa-tion. Patients with facet subluxation and advance-staged compression-flexion fractures (stages 4 or 5) were a distinct group when treated conservatively with a halo. Despite anatomic reduction, facet subluxations associated with advance-staged compression-flexion fractures (stages 4–5), might be best treated surgically. Risk factors for late halo failure should include sublimations with advance-staged compression-flexion fractures when treated conservatively.
