Abstract
in English, French

Expansive laminoplasty, a procedure used more and more often for cervical myelopathy, was carried out in patients with lumbar spinal stenosis in the Department of Orthopaedics, Paraplegia, Physical Medicine and Rehabilitation of our institute. Twenty-five such clinico-radiologically proven cases were operated upon. For radiological evaluation, computed tomography (CT) was used. Expansive laminoplasty decompresses the nerve roots by osteoplastic enlargement of the lumbar spinal canal, with the maintenance of spinal stability. These advantages were confirmed during the follow-up of 3 to 5 years. Using CT, the spinal canal was found to be enlarged to a nearly rectangular shape and the average enlargement was 124%. The visual analogue scale (VAS) was used for subjective pain assessment before and after the surgery. The ultimate outcome was assessed by the Surin et al. criteria (Spine 17:1-8, 1992).

Nous réalisons habituellement, dans notre département de chirurgie orthopédique, de traitement des paraplégiques, de médecine physique et rééducation, dans les myélopathies cervicales une laminoplastie étendue. Dans ce contexte, nous avons opéré 25 patients qui ont été explorés sur le plan radiologique et scanographique. La laminoplastie étendue entraîne une décompression des racines nerveuses et un élargissement du canal tout en permettant un maintien de la stabilité rachidienne. Ces avantages ont été confirmés par le suivi des patients sur une période de 3 à 5 ans. L’élargissement du canal a été en moyenne de 124%. Nous avons utilisé une échelle visuelle analogique pour analyser la douleur avant et après l’intervention chirurgicale. Le devenir de ces patients a été également étudié selon les critères de Surin et collaborateurs.
