title: [Imaging of the lumbar spine after diskectomy].
abstract: The radiological investigation of persistent or recurrent sciatica after lumbar diskectomy essentially consists of demonstrating recurrent disk herniation. Comparison between plain and contrast enhanced CT or MR examinations at the level of the diskectomy is the main step of the radiological survey. The meanings of the various radiological findings are discussed. Other lesions that may induce persistent sciatica after lumbar diskectomy include degenerative narrowing of the lateral recess, spinal instability, stress fracture of the remaining neural arch, pseudo-meningomyelocele after laminectomy.
