Background Context:
Traumatic spinopelvic dissociation, sometimes referred to as U-shaped sacral fracture, is a very rare high-energy trauma. The surgical management of spinopelvic dissociation includes decompression, reduction, and fixation.
Purpose:
We report a novel surgical technique for the treatment of spinopelvic dissociation that uses growing rods and a pedicle screw system, which is often used to treat patients with early onset scoliosis.
Study Design:
This case report used a technical report of spinopelvic dissociation surgery using spinopelvic fixation and the growing rod technique.
Patient Sample:
One case was used as the patient sample.
Outcome Measure:
Radiographic outcomes, including plain X-ray, three-dimensional computed tomography, and magnetic resonance imaging scan were the outcome measures.
Methods:
The radiographic outcomes were compared preoperatively, postoperatively, and at the 1-year follow-up with bony union.
Results:
Growing techniques improved traumatic sacral angulation, displacement, and canal encroachment, and provided sufficient structural support.
Conclusion:
The growing rod technique for spinopelvic dissociation under intraoperative neurophysiological monitoring could be a useful alternative surgical option, especially in patients without neurologic deficit.
