Summary
We report 57 cases of the Klippel-Feil syndrome. Five had type I congenital cervical fusion, 48 type II and 4 type III. The symptoms and signs varied considerably. Patients with C2–C3 fusion often had symptoms associated with odontoid dysplasia and occipito-cervical instability. Twenty-one had progressive neurological symptoms and 19 were operated on: 3 had occiput-C3 posterior arthrodeses, 2 a single level fusion, 1 a laminectomy and anterior arthrodesis, and 13 had laminoplasties. Degenerative changes at the unfused segment and a narrow bony canal are high risk factors in the development of neurological compromise.
Résumé
Les auteurs rapportent 57 cas de syndrome de Klippel-Feil. D'après la classification de Feil, 5 des patients avaient une fusion de type I, 48 une fusion de type II et 4 une fusion de type de III. Il n'y avait pas de prévalence sexuelle notable et les symptômes étaient très variés. Les patients avec fusion C2–C3, présentaient souvent une dysplasie de l'apophyse ondotoïde avec instabilité cervicooccipitale. 21 patients ont eu des déficits neurologiques progressifs et 19 d'entre-eux ont du être opérés: 3 pour une arthrodèse postérieure occipito-C3, 2 pour une arthrodèse antérieure en un seul niveau, 1 par laminectomie et arthrodèse antérieure et 13 par laminoplasie. En plus de la pathologie dégénérative se développant au niveau du segment non fusionné, un canal cervical étroit au niveau du segment atteint de syndrome de Klippel-Feil représente un facteur de risque important de troubles neurologiques.
