Summary
Electroneuromyography (ENMG) and myelography aid in diagnosing cervical radiculopathy. Combining these tests helps assess root compression and functional significance of deformities.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Cervical radiculopathy and myelopathy present diagnostic challenges.
- Accurate preoperative assessment is crucial for effective treatment.
Purpose of the Study:
- To evaluate the diagnostic accuracy of electroneuromyography (ENMG) and myelography.
- To determine the complementary role of ENMG and myelography in diagnosing cervical root compression.
Main Methods:
- Retrospective analysis of 77 patients with cervical radiculopathy/myelopathy.
- Assessment of ENMG findings (localization, specificity, normality).
- Evaluation of myelography findings (operated and non-operated root levels).
Main Results:
- ENMG identified the affected root level in 57% of patients (1-2 segment accuracy).
- Myelography showed distinct findings in 79 of 97 operated root levels.
- Combining ENMG and myelography improved assessment of root sheath deformities.
Conclusions:
- ENMG and myelography play complementary roles in diagnosing cervical radiculopathy.
- Integrated interpretation of ENMG and myelography aids in assessing functional significance of root compression.
