Treatment of 6 Oases of Extraforaminal Disc Herniation

518 cases of lumbar disc herniation were surgically treated over the past 16 years. Of these, we report 6 cases of extraforaminal disc herniation (1.2%). The mean age of the patients at surgery was 54.8 years. We used on two surgical approaches; anterior approach (anterior spinal fusion) and posterior approach (hemi-facetectomy, laminectomy and osteoplastic hemi-laminectomy). One case in whom we performed a laminectomy achieved a poor result. In that patert we diagnosised extraforaminal lumber disc herniation. All other cases achieved good or excellent results.
