The purpose of this systematic review is to investigate which minimally invasive techniques have been used for discectomy in recurrent lumbar disc herniation (LDH), to present the success and complication rates and to evaluate the advantages and limitations of each technique. Discectomy for recurrent LDH is accompanied by a higher morbidity rate compared with primary LDH. Because of the limited operating field, the majority of surgeons have been discouraged from utilising a minimally invasive approach for revision surgery. ⋯ All three techniques have a low delayed instability rate. MED, ETD and EID are safe and efficient treatment options for surgical management of recurrent LDH with good success and low complication rates. At the same time, they offer the advantages of minimally invasive access.
