Analysis of risk factors and postoperative predictors for recurrent lumbar disc herniation

Background: This study identified risk factors and postoperative indicators for recurrent lumbar disc herniations (rLDH) following microdiscectomy. Methods: We retrospectively reviewed the 1-year recurrence rate for LDH in 209 consecutive patients undergoing microdiscectomy (2013–2018). Results: Utilizing a multivariate analysis, higher body mass index (BMI) and postsurgery Oswestry disability index (ODI) were significantly associated with an increased risk of rLDH. Conclusion: Elevated postsurgery ODI and higher BMI were significantly associated with increased risk of rLDH.
