Summary
Diagnostic imaging for radicular leg pain often mismatches surgical findings. Computer tomography and myelography are crucial for spinal stenosis and prior disc surgery, but precautions can improve accuracy.
Area of Science:
- Neurosurgery
- Radiology
- Orthopedic Surgery
Background:
- Radicular leg pain is a common symptom requiring accurate diagnosis.
- Diagnostic imaging plays a critical role in pre-operative planning for spinal conditions.
- Evaluating the concordance between imaging and surgical findings is essential for improving patient outcomes.
Observation:
- 109 patients with radicular leg pain underwent both computer tomography (CT) and myelography before surgery.
- Discrepancies between CT, myelography, and surgical diagnoses occurred in 41 cases (37.6%).
Findings:
- The most common reasons for diagnostic discrepancies included bony spinal canal stenosis, scar formation, and intra- or extraforaminal herniation.
- In patients with spinal stenosis or a history of disc surgery, performing both CT and myelography is recommended.
- Implementing specific precautions during CT and myelography may decrease the incidence of discordant findings.
Implications:
- Accurate pre-operative diagnosis is vital for successful surgical intervention in radicular leg pain.
- Combined use of CT and myelography, with procedural precautions, can enhance diagnostic accuracy.
- Further research into optimizing imaging protocols may reduce surgical complications and improve patient management.
