[The value of myelography, computerized tomography and course of pain for the diagnosis of recurrent herniated disk].

29 patients with recurring symptoms after lumbar disk surgery have been examined with computed tomography and myelography before they underwent a reoperation. This study shows that the myelography has the higher diagnostic accuracy than the CT concerning the differentiation between recurrent disk herniation and scar. The analysis of clinical features is helpful in predicting the etiology of the recurring symptoms.
