Key Clinical Findings & Highlights
- Compares short-segment vs. long-segment posterior spinal instrumentation.
- Proves motion-segment preservation with reduced operative blood loss.
- Achieves durable sagittal spinal alignment and neurological decompression.
Abstract
Introduction & Background
The thoracolumbar junction is biomechanically vulnerable as it transitions from the rigid thoracic rib cage to the mobile lumbar spine. Posterior instrumented reduction restores sagittal alignment and canal clearance without anterior thoracotomy morbidity.
Clinical Case Presentation & Diagnosis
Sixty patients with unstable AO Type A3/A4 thoracolumbar burst fractures and neurological deficit underwent posterior pedicle screw instrumented stabilization. Cohorts were divided into Group 1 (Short-segment index level screw fixation) and Group 2 (Long-segment fixation).
Surgical Technique & Management
Posterior transpedicular reduction, posterolateral decompression where required, and anatomical rod contouring were performed under fluoroscopic guidance.
Discussion & Literature Context
Short-segment fixation incorporating the fractured vertebra achieved comparable correction of Cobb's kyphotic angle (mean correction 14.8° vs 15.2°) with significantly reduced operative time (95 mins vs 142 mins) and preserved more motion segments compared to long-segment constructs.
Conclusion
Short-segment pedicle screw instrumentation including the fractured vertebra is safe, effective, and motion-preserving for thoracolumbar burst fractures.
