创伤性寰枢椎不稳的影像学诊断及Apofix手术治疗

Image dirgnosis and apofix operation on traumatic atlantoaxial instability

目的:探讨创伤性寰枢椎不稳的影像学诊断特点,并评价APOFIX椎板钩内固定手术治疗的效果。方法:对三例创伤性寰枢椎不稳进行X线、螺旋CT、MRI等影像学检查。并对其中两例实施寰枢椎后路融合、植骨、APOFIX椎板钩内固定手术。结果:X线、螺旋CT、MRI显示两例齿状突骨折伴寰枢椎不稳,另一例显示寰椎爆裂骨折。术后随访3-6个月,X线复查示均获骨性愈合。结论:X线、螺旋CT、MRI均是检查创伤性寰枢椎不稳的重要方法,需结合使用;寰枢椎后路融合、植骨、APOFIX椎板钩内固定手术是治疗枢椎齿状突骨折伴寰枢椎不稳的简单、安全、有效的方法。

Objective: To research the image dirgnostic characteristics of traumatic atlantoaxial instability and evaluate the effect of posterior atlantoaxial fusion operation using Apofix interlaminar clamp instruments. Methods: Three patients with traumatic atlantoaxial instability were proceded X-ray, CT, MRI examinations. Operations of posterior atlantoaxial fusion using Apofix instruments with autologous bone grafts were performed on two patients with odontoid fractures. Resalts: Two cases of odontoid fiactures and atlantal instability were detected by radiography, CT, MRI, while the other case shown adantal burst fracture. The patients were followed up for 3-6 months, with cervical radiograph shown solid osseous unions.Conclusion: Radiography, CT, MRI are important diagnostic methods of odontoid fractures with atlantoaxial instability, need to be applied jointly Posterior atlantoaxial fusion using Apofix interlaminar clamp fixation instruments is recommended to treat odontoid fractures with atlantosxial instabilit for its practicality, safety and effectiveness.
