Radiographic predictors of lumbar disc re-herniation requiring repeat discectomy or fusion: a matched retrospective cohort analysis

Key Points

• Re-herniation of lumbar discs occurs in patients after initial surgery, necessitating repeat intervention shortly thereafter.
• Rates of repeat discectomy or fusion were analyzed over a median follow-up period of 20 months in a matched cohort study with 150 patients.
• Radiographic predictors were evaluated using imaging studies from patients with prior lumbar disc surgeries, informing future interventions.
• Findings underline the importance of identifying specific radiographic markers to enhance surgical planning and patient outcomes.
