Abstract.

We studied the outcome of expansive laminoplasty in 37 patients with cervical spondylotic myelopathy. Patients were divided into two groups according to the recovery rate (RR) – a 'good' group (n=19), and a 'fair' group (n=18). Patients in the good group showed a greater pre-operative Japanese Orthopaedic Association (JOA) score, a greater compression ratio, and a larger Pavlov ratio (P<0.05). The presence of high signal intensity on MRI proved to be of no prognostic importance.

Résumé.

Nous avons étudié le résultat des laminoplasties d'expansion chez 37 malades atteint de myelopathie spondylotique cervicale. D'après le taux de récupération les malades ont été divisés en un groupe 'bon' (n=19) et un groupe 'juste' (n=18). Les Malades dans le groupe bon avaient un score JOA plus élevé en préopératoire, un plus grand taux de compression, et un ratio de Pavlov plus grand (P<0.05). La présence d'un signal de haute intensité sur l'IRM n'avait pas d'importance pronostique.
