A Levering Technique Using Small Parallel Rods for Open Reduction of High-Grade Thoracolumbar Dislocation.

Abstract

Technical report. Dorsolumbar vertebral dislocations, with or without associated fractures, occur secondary to very high velocity trauma. The reduction procedures and techniques, which may be adopted in these situations, have been multifariously discussed in the literature. Our objective was to assess the outcome of a novel reduction maneuver, using parallel rods which we have employed in reduction of high-grade thoracolumbar fractures to achieve precise sagittal balance as well as accurate vertebral alignment with minimal soft tissue damage. The study included a total of 11 cases of thoracolumbar dislocations, who had presented to our emergency spine services following high-velocity trauma. After appropriate systemic stabilization and necessary investigations, all patients were surgically treated using the described technique. There were no surgical complications at 2-year follow-up. Radiographs showed good reduction and maintained sagittal balance. We believe that this technique is an excellent means of achieving safer, easier, and accurate reduction for restoration of sagittal/coronal balance and alignment in high-grade thoracolumbar dislocations. It is easily reproducible and predictable.
