Randomized trial shows discectomy improves outcomes in patients with lumbar disc herniation and radiculopathy, suggesting its necessity.

To evaluate the effectiveness of discectomy surgery for treating lumbar disc herniation with persistent radiculopathy.
Literature review of treatment outcomes for lumbar disc herniation
Analysis of discectomy techniques: open, microtubular, and endoscopic
Assessment of recurrent herniation rates and annular closure methods
Discectomy significantly improves symptoms in patients with pain lasting over 6 weeks compared to nonsurgical treatment.
Patients with large annular defects (≥6 mm) have a higher risk of recurrent herniation and require more revisions.
Bone-anchored devices effectively reduce rates of recurrent disc herniation in high-risk patients.

Lorio et al. (2020) studied this question.
