To evaluate the orthopedic effects of internal fixation of cervical pedicle screw on cervical spondylotic myelopathy with cervical kyphosis.
Seventeen patients with cervical spondylotic myelopathy with cervical kyphosis with the Cobb's angle >10 degrees underwent internal fixation of cervical pedicle screw. The patients were followed up for 13. 8 months. The Cobb's angle of cervical kyphosis was measured before operation, one week after-operation, and upon the final follow up. The neural function and cervical spine stability were evaluated using Japanese Orthopedic Association (JOA) scoring system.
The average preoperative Cobb's angle of cervical kyphosis was -16.1 degrees before operation, was -3.3 degrees one week after operation, and was -3.8 degrees at the final follow-up. Follow-up 6 months after operation and at the final follow up showed that the fused segments were stable. The JOA score improved by 5.2 +/- 1.6 (P < 0.05) with a mean JOA score improvement rate of 64. 3%. No neurovascular and instrumentation-related complications occurred.
Internal fixation of cervical pedicle screw is effective and safe in treatment of cervical spondylotic myelopathy with cervical kyphosis.
评估颈椎椎弓根螺钉内固定术治疗伴颈椎后凸的脊髓型颈椎病的矫形效果。
对17例伴颈椎后凸（Cobb角>10度）的脊髓型颈椎病患者行颈椎椎弓根螺钉内固定术。对患者进行了13.8个月的随访。分别于术前、术后1周及末次随访时测量颈椎后凸的Cobb角。采用日本骨科协会（JOA）评分系统评估神经功能和颈椎稳定性。
术前颈椎后凸平均Cobb角为-16.1度，术后1周为-3.3度，末次随访时为-3.8度。术后6个月及末次随访显示融合节段稳定。JOA评分提高了5.2±1.6（P<0.05），平均JOA评分改善率为64.3%。未发生神经血管及内固定相关并发症。
颈椎椎弓根螺钉内固定术治疗伴颈椎后凸的脊髓型颈椎病有效且安全。
