Summary
Expansive laminoplasty, a procedure used for cervical myelopathy, was carried out in 4 patients with degenerative lumbar spinal stenosis. The method was used in relatively young patients with severe low back and sciatic pain who had intraspinal ossification at multiple segments, with or without developmental spinal stenosis. The advantages of osteoplastic enlargement of the lumbar spinal canal with reinforcement of spinal stability are confirmed by our follow up of 2 to 5 1/2 years. The results were very satisfactory in each case. The indications and operative technique are described.
Résumé
La laminoplastie étendue, technique utilisée dans les myélopathies cervicales, a été réalisée chez quatre malades porteurs d'une sténose rachidienne lombaire d'origine dégénérative. L'intervention a été pratiquée chez des sujets relativement jeunes, présentant d'importantes douleurs lombaires et sciatiques et qui avaient des ossifications intra-canalaires à de nombreux niveaux, avec ou sans sténose évolutive. Les avantages de l'élargissement ostéoplastique du canal rachidien lombaire avec renforcement de la stabilité vertèbrale sont démontrés par l'évolution de nos cas, avec un recul de 2 à 5 ans et demi. Les résultats sont satisfaisants dans tous les cas. Description de la technique opératoire et discussion des indications.
