✦ Synopsis

Forty-seven patients with cervical myeloradiculopathy due to ossification of the posterior longitudinal ligament were treated by laminoplasty. The spinal canal from C3 to C7 was opened en bloc unilaterally and a spacer bone graft inserted to separate the floating laminae. The average follow up was 7.3 years (range 5 to 11 years). Favourable results were obtained in 35 patients and even though they had serious postoperative symptoms those with advanced neurological symptoms before operation showed considerable improvement. Late results were poor in patients who had greater than 50% compromise of the spinal canal by the ossified lesion. Laminoplasty is a safer method of obtaining favourable late results in patients with involvement of more than 3 vertebrae, but in those with a more severe compromise of the spinal canal by ossification, additional anterior decompression may be necessary later.

Habituellement le canal rachidien a dtd ouvert "en bloc" de C3 & C7, d'un seul c6tg, puis compl~t~ par une greffe osseuse afin de maintenir l'ouverture au niveau de la lame. On a utilis~ la cotation de l'Association orthopddique
