Summary
Chemonucleation for lumbar disc herniation shows positive clinical outcomes correlating with reduced thecal sac defect size and increased peridiscal signal on MRI scans. These imaging changes indicate successful treatment and healing.
Area of Science:
- Radiology
- Neurosurgery
- Orthopedics
Background:
- Lumbar disc herniation is a common cause of back pain.
- Chemonucleation is a minimally invasive treatment option.
- MRI is crucial for evaluating treatment efficacy.
Purpose of the Study:
- To correlate post-chemonucleation clinical outcomes with lumbar MRI findings.
- To identify specific MRI changes associated with successful chemonucleation.
Main Methods:
- Retrospective analysis of 12 patients undergoing chemonucleation.
- Clinical outcome assessment at last follow-up.
- Lumbar MRI scans analyzed for thecal sac defect size and peridiscal signal.
Main Results:
- Eight of 12 patients showed clinical improvement.
- Improved patients exhibited decreased thecal sac defect dimensions.
- Seven of eight improved patients showed increased peridiscal signal.
- Non-improved patients had fewer defect size reductions and less peridiscal signal increase.
Conclusions:
- Lumbar MRI changes, specifically reduced thecal sac defect and increased peridiscal signal, correlate with positive clinical outcomes after chemonucleation.
- MRI findings can help predict treatment success in chemonucleation therapy.
