Objectives: The results of surgical treatment for recurrent lumbar disc herniation using repeat microdiscectomy were analyzed. In addition, the recurrence of lumbar disc herniation was evaluated according to age, gender, surgical disc segment, recurrence development time, and the type of modic change observed. Methods: Between 2012 and 2016, 40 recurrent lumbar disc herniation cases were operated on in the clinic. The patient charts were analyzed retrospectively. Results: Of the total, 17(42.5%) of the patients were female and 23 (57.5%) were male. The age of the patients ranged from 28 to 71 years (mean: 48±10 years). The interval between primary surgery and the development of recurrent herniation was between 6 and 60 months, with a mean of 19 months (19±16) months. The distribution of the operated level was as follows: 26 (65%) at L4-5, 11 (27.5%) at L5-S1, 2 (5%) at L3-4, and 1 (2.5%) at L2-3. In 85% of the cases (34 patients), there were modic changes in the first surgery. Conclusion: Recurrent lumbar disc herniation is an important problem in spinal surgery. In this study group, a mean of 48 years of age and modic changes in the primary surgery were observed. At the postoperative 19th month, the probability of recurrence increased. In cases where spinal instability is not detected, successful pain control can only be achieved with repeat microdiscectomy.
