Surgical procedure presented here was evolvedfrom observations either in cadavers or in the cer-vical vertebral columns removed en bloc at autopsy.Ventro-doral pressure was excerted to the ventralaspect of the dural tube through a burr hole placedin the vertebral bodies and the effects of dorsalmigration were compaired between the cases with laminectomy alone and with laminectomy plusbilateral facetectomy. More extensive dorsal migra-tion was obtained by bilateral facetectomy pulslaminectomy. No limitation of movement of cer-vical cord was observed by the dentate ligament tothe ventro-doral pressure.

Ten case of the ectopic ossification of the post-erior longitudinal ligament producing spinal cordcompression have been described. Although thisdisease may represent a different manifestation ofthe degenerating changes, this disease should beincluded in the differential diagnosis of cervicalmyelopathy because of its unique clinical, radiolo-gical and pathological behaviour and it seems toconstitute a distinct clinical entity. Ten patientstreated by the extensive decompressive laminectec-tomy with or without foramen magnum decom-pression associated with bilateral multiple facetec-tomy had favorable results. Postoperative myelo-graphy demonstrated the rationale with dorsalmigration of the entire dural contents.
