Summary
This study shows that modified posterolateral decompression and Harrington rod instrumentation effectively treat unstable thoracolumbar burst fractures. This surgical approach improved neurologic deficits and reduced complications compared to other methods.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Unstable burst fractures of the thoracolumbar junction pose significant risks.
- Conventional radiography often misses posterior element fractures crucial for diagnosis.
Purpose of the Study:
- To evaluate the efficacy of a modified posterolateral decompression and Harrington rod instrumentation for unstable thoracolumbar burst fractures.
- To assess the role of computed tomography (CT) in diagnosing these injuries.
Main Methods:
- Sixteen patients with unstable thoracolumbar burst fractures underwent modified posterolateral decompression and Harrington rod instrumentation.
- Preoperative CT scans were utilized to assess spinal canal diameter and neural impingement.
- Conventional radiography was compared to CT findings.
Main Results:
- CT accurately identified neural impingement and revealed posterior element fractures missed by conventional radiography.
- All 12 patients with preoperative neurologic deficits showed improvement.
- Five of eight patients with conus medullaris lesions achieved full recovery.
Conclusions:
- Modified posterolateral decompression with Harrington rod instrumentation is an effective treatment for unstable thoracolumbar burst fractures.
- CT is superior to conventional radiography for diagnosing associated posterior element fractures.
- This one-stage procedure reduces kyphosis, neurologic deterioration, and back pain.
