Summary
Older age and higher body mass index are risk factors for recurrence after percutaneous endoscopic lumbar discectomy (PELD). Protrusion and Modic changes on imaging also indicate higher recurrence risk following PELD.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Minimally Invasive Spine Surgery
Background:
- Percutaneous endoscopic lumbar discectomy (PELD) is a prevalent surgical technique for lumbar disc herniation.
- Limited research exists on factors contributing to symptom recurrence after PELD.
Purpose of the Study:
- To identify and analyze risk factors associated with recurrence after successful PELD.
- To improve patient outcomes by understanding predictors of PELD failure.
Main Methods:
- Retrospective analysis of medical records and radiological studies.
- Comparison of 42 patients with recurrent disc herniation (recurrent group) versus 42 patients with satisfactory PELD outcomes (non-recurrent group).
Main Results:
- The recurrent group had a significantly higher mean age (47.4 vs 34.4 years, p=0.001) and body mass index (24.9 vs 22.9, p=0.006).
- Radiological findings of disc protrusion (p=0.013) and Modic changes (p=0.003) were more frequent in the recurrent group.
Conclusions:
- Older age, higher BMI, disc protrusion, and Modic changes are significant risk factors for recurrence after PELD.
- Surgeons should carefully consider these factors to optimize PELD success rates and patient selection.
