Post-laminectomy and post-fusion stenosis of the lumbar spine.
On the basis of a 9-year experience with 231 patients with post-laminectomy and post-spinal fusion stenosis of the lumbar spinal canal, we emphasize the importance of recognizing and adequately decompressing such lesions. In the majority of such patients pain relief has been achieved, but some of the failures can be attributed to technical reasons. Most failures are due to associated lesions and to functional factors. A special surgical techniy be advisable. The indications for fusion however were few and require further investigation and evaluation. The significant failure rate points to the need for continuing research into the causes of low back pain and adequate management programs for the patient with the "multiple operated back" who still has disabling pain and drug dependence.
