OBJECTIVE
To determine the effect of cervical pedicle screw in the treatment of cervical fracture complicating ankylosing spondylitis.
METHODS
A retrospective study was done in 5 patients of cervical fracture complicating ankylosing spondylitis who were treated with cervical pedicle screw. According to Frankel's standard, 1 patient was in Grade A, 2 patients in Grade B and 1 patient in Grade C and 1 patient in Grade D. All patients were treated with decompression, fusion and posterior fixation with cervical pedicle screw.
RESULTS
The average bony healing time was 3.6 months (3.1 to approximately 4.5 months). The instrumentation was not loose, pulled-out or ruptured. Only one C6 pedide was perforated and the vertebral artery was broken, but there was no new postoperative symptom. Three of the patients with neurological deficits improved postoperatively but the other two who were in Grade A were remained unchanged.
CONCLUSION
The good biomechanical characteristics of cervical pedicle screw help the successful treatment in the application of cervical fracture complicating ankylosing spondylitis.
目的
确定颈椎椎弓根螺钉在治疗强直性脊柱炎合并颈椎骨折中的作用。
方法
对5例接受颈椎椎弓根螺钉治疗的强直性脊柱炎合并颈椎骨折患者进行回顾性研究。根据Frankel标准，A级1例，B级2例，C级1例，D级1例。所有患者均接受减压、融合及颈椎椎弓根螺钉后路固定治疗。
结果
平均骨愈合时间为3.6个月（3.1至约4.5个月）。内固定未松动、拔出或断裂。仅1枚C6椎弓根穿孔，椎动脉破裂，但术后无新症状出现。3例神经功能缺损患者术后改善，另2例A级患者无变化。
结论
颈椎椎弓根螺钉良好的生物力学特性有助于成功治疗强直性脊柱炎合并颈椎骨折。
