Treatment of subacute thoracic spine fracture-dislocation by total vertebrectomy and spine shortening: technical note.

Vertebral resection with spine shortening has been primarily reported for the treatment of demanding cases of nontraumatic disorders. Recently, this technique has been applied to the treatment of traumatic disorders. The current treatment of vertebral fracture-dislocation when there is partial or total telescoping of the involved vertebrae is a combined anterior-posterior approach with corpectomy, anterior support implant, and further posterior instrumentation. These procedures usually require 2 surgical teams, involve longer operating times and greater risk of surgical complications related to the anterior approach, and commonly entail longer postoperative care before discharge. The authors report on 2 patients with high thoracic fracture-dislocations with telescoping (T-2 and T-4) who were treated in the subacute phase with total spondylectomy (T-3 and T-5, respectively) and spine shortening by using only a posterior approach. Complete recovery of the sagittal balance was achieved with this technique and the postoperative periods were clinically uneventful. One patient presented with asymptomatic hemothorax that did not require drainage. In paraplegic patients with anterior thoracic dislocation fractures in which one vertebral body blocks the reduction of the other, total spondylectomy and spine shortening seem to be a reasonably safe and effective technique.
