Postoperative scars and recurrent disk herniation: clinical, neuroradiological, and surgical findings

Authors present 36 patients with recurrent sciatica or low-back pain after lumbar disk operation. All patients were submitted to clinical and instrumental devices. CT-scan was performed in 36 patients, 12 underwent myelography and 4 EMG. Authors verified reliability of clinical and instrumental devices on the basis of surgical results. We believe that myelo-CT is actually the first choice investigation in the neuroradiological ones. In the near future MRI will take its place in investigating spinal pathology.
