title: Lumbar spinal stenosis by postdiscectomy hyperostosis.
abstract: The mesenchymal repair process of the connective tissue in the surgical wound following lumbar laminectomy presents three aspects: postoperative epidural scar, heterotopic bone formation in the epidural scar and vertebral hyperostosis around laminectomy. Twelve cases of lumbar spine hyperostosis consecutive to laminectomy, confirmed by x-ray findings and surgery are presented. The main symptom at presentation was a recurrent sciatic neuritis. Lumbo-sacral spine films showed a "bright" focal condensation in the previous surgical. Lamina inferior and superior and the articular facets were hypertrophic. Surgery confirmed the hyperostosis and compressive lumbar spine stenosis or foramen stenosis.
