RESUMO
METHODS: Between January 2010 and January 2012, 58 patients with cervical radiculo-myelopathy were treated by posterior cervical decompressive laminectomy and lateral mass screw fixation combined with foraminotomy. There were 31 males and 27 females, with an average age of 52.7 years (range, 41-72 years). The mean disease course was 5.4 years (range, 3-15 years). The preoperative Japanese Orthopaedic Association (JOA) score was 7.8±1.3, and visual analogue scale (VAS) score was 6.8±1.7. There were 37 cases of inter-vertebral disc herniation and ligamentum flavum hypertrophy, 11 cases of vertebral osteophyte formation with the osteophyte spinal canal occupational ratio of 51.7%±18.1%, and 10 cases of inter-vertebral disc herination with cervical instability. Preoperative cervical curvature was (-5.5±12.5)°. The fixed segments included C3-7 in 29 cases, C4-7 in 19 cases, and C3-6 in 10 cases. Foraminotomy was performed in 135 nerve foramina (mean, 2.33 foramina).
