Summary
Lumbar disc hernia recurrence after surgery is common. Higher disc height, greater spinal canal occupation by the hernia, and facet joint degeneration increase recurrence risk.
Area of Science:
- Neurosurgery
- Orthopedics
- Spinal Surgery
Background:
- Lumbar disc hernias frequently necessitate surgical intervention.
- Hernia recurrence presents a significant post-operative complication.
Purpose of the Study:
- To identify risk factors linked to lumbar disc hernia recurrence.
- Analysis focused on patients undergoing surgery at our institution.
Main Methods:
- Retrospective analysis of lumbar microdiscectomies (2010-2014).
- Exclusion of patients with prior surgeries, extraforaminal, or foraminal hernias.
- Comparison between recurrent hernia (case) and non-recurrent (control) groups.
Main Results:
- 16% recurrence rate (30/177 patients), with 27 reoperations.
- Associated risk factors included increased disc height, greater spinal canal occupation by the hernia, and degenerative facet joint changes.
- No significant differences observed in sex, body mass index, or age.
Conclusions:
- Findings indicate increased disc height and spinal canal occupation are key predictors of recurrence.
- Degenerative facet joint changes also correlate with higher recurrence rates.
- These factors are crucial for surgical planning and patient counseling.
