Introduction: MRI scan has been deemed the gold standard in diagnosis of lumbar disc prolapse. Preoperative evaluation for accurate identification of the culprit fragment and pain generators . We set out to correlate the relationship between clinical features, MRI findings and intra operative findings in cases of lumbar disc prolapse.
Material and Method: Over a two year period, 50 consecutive patients with low back pain, MRI of whom indicated the need for operative intervention were included in the study. MRI findings were reported by the radiology dept.
Result: MRI has a sensitivity of 92% and a specificity of 78% in disc prolapsed. However MRI scan alone has a tendency to over diagnose disc with regards to level as all degenerative disc bulges may not necessarily be symptomatic. In such a situation adding clinical findings to the above increases the accuracy of culprit disc identification by 22.5% . High intensity zones on MRI corresponded to annular tears intra operatively and these patients had significantly higher VAS scores..
Conclusion: 1.5 Tesla MR images show enough detail with clarity to accurately identify the culprit disc level in cases of lumbar disc prolapse. Attention to clinical findings help pinpoint intervention requiring levels.
