During 1981-1989, we operated on 271 patients with lumbar disc hernia for the first time. Sixteen cases were reoperated on due to recurrence of symptoms. Of these, 14 were male and 2 were female ranging in age from 24-62 years, (mean; 46.7 years). The recurrence rate was 5.9% and recurrence period ranged from 6-70 months, (mean; 42 months).The level of the initial operation was L3/4 in 2, L4/5 in 10, L5/6 in 1, and L5/S1 in 6 cases. The surgical technique used was Love's method in 13, hemilaminectomy in 2, and ABF in 1 case. The herniation recurred at the same site in 5, and at the opposite side of the same disc in 8. Recurrence occurred at another disc level in 3 cases.The posterior approach was used in the second operations, with extirpatation of the recurrend disc hernias. PLF were added in 2 cases with unstable vertebrae at the affected site.Excellent results were achieved in 15 cases allowing them to return to full-time employment.
