Summary
Long-term outcomes for lumbar disc herniation surgery show reoperation significantly impacts results. Patients not reoperated had better outcomes, highlighting the importance of initial surgical success in spinal surgery.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Orthopedic Surgery
Background:
- Evaluating long-term outcomes of lumbar disc herniation surgery.
- Neurosurgical department training spinal surgeons.
- Comparison of conventional and microsurgical techniques.
Purpose of the Study:
- Assess long-term patient outcomes after lumbar disc herniation surgery.
- Investigate the impact of reoperations on surgical outcomes.
- Compare outcomes between microsurgical and conventional surgical techniques.
Main Methods:
- Retrospective data collection from patient files (1988-89).
- 211 patients with lumbar disc herniation and unilateral sciatica underwent surgery.
- Standardized questionnaires assessed pain, functional status, and reoperations in 1997.
Main Results:
- 163 patients (77%) responded to the questionnaire.
- 24% of patients (39) required reoperation.
- Median outcome score was significantly better for non-reoperated (10.5) versus reoperated patients (45.0).
Conclusions:
- High reoperation frequency noted in lumbar disc herniation surgery.
- Satisfactory outcomes observed in non-reoperated patients 7-9 years post-surgery.
- Retrospective design limits conclusions on technique superiority (microsurgical vs. conventional).
