Summary
Computed tomography (CT) accurately identifies lumbar degenerative diseases and nerve root compression. CT findings closely correlate with surgical outcomes, aiding in precise localization for treatment.
Area of Science:
- Radiology
- Neurosurgery
- Orthopedics
Background:
- Lumbar degenerative diseases present diagnostic challenges.
- Accurate identification of nerve root compression is crucial for surgical planning.
Purpose of the Study:
- To evaluate the correlation between CT findings and surgical exploration in patients with lumbar degenerative diseases.
- To determine the utility of CT in localizing nerve root compression.
Main Methods:
- Retrospective review of CT scans from 18 patients who underwent surgical exploration.
- High-resolution CT scans were obtained using a Somatom II scanner.
- Slice thickness was 4 mm, with lateral localizer images for disk space selection.
Main Results:
- CT identified bony canal stenosis, soft tissue abnormalities (e.g., herniated nucleus pulposus), and spinal instability.
- These factors contribute to spinal canal narrowing and nerve root compression.
- Lack of nerve root delineation in CT suggested compression, correlating with surgical findings.
Conclusions:
- CT findings closely correlate with surgical findings in lumbar degenerative diseases.
- CT is effective in determining the site of nerve root compression.
- This aids in precise surgical planning and treatment of lumbar spine conditions.
