This 2010 narrative review by Lee et al. synthesizes the definition, risk stratification, diagnostic workup, and surgical decision-making for recurrent lumbar disk herniation — the most common complication after primary open diskectomy — drawing on comparative surgical technique data and clinical outcomes literature.
When a post-diskectomy patient returns with radicular pain, use gadolinium-enhanced MRI to distinguish true reherniation (no early enhancement, dural displacement) from epidural scar (early enhancement, dural retraction) before planning reoperation — scar alone responds poorly to surgery.
If you find reherniation plus radiographic instability (translation ≥3 mm at L1–4, ≥5 mm at L5–S1, or >10° angulation), plan fusion with pedicle screw fixation rather than diskectomy alone.
