Recurrent lumbar disc herniation is a common disease process. It has been noted to occur in 5 to 15% of cases surgically treated for primary lumbar disc herniation. Outcomes in one series approached those after the initial operations, although this is not the case in the experience of most surgeons.
The removal of recurrent lumbar disc herniations requires meticulous surgical technique. Great care is taken to identify the osseous margins of the previous surgical site. Identification and dissection of scar from the dura mater is greatly aided with the use of a microscope.
