简要总结
Odontoid fracture is a common fracture accounting for 10-15% of all cervical fractures. It occurs in bimodal fashion in elderly and young patients.
The classification of Anderson and Alonzo provides a guide for prognosis . Type I and type III have a good rate of union, while type II has a poor prognosis due to poor blood supply. Hence, operative fixation is recommended to avoid non-union.
Treatment options for type II include anterior odontoid screw fixation and posterior C1-C2 fusion.Despite the excellent rates of bony union in posterior C1-C2 fusion, it is associated with higher morbidity, higher blood loss and significant limitation in the range of motion and rotation of the neck.the aim of the study Is to evaluate clinical and radiological outcome of anterior odontoid screw osteosynthesis in treatment of type 2 odontoid fracture.

结局指标
主要结局
Association for the study of internal fixation(AO) neck disability index.
时间窗: 1 year
AO neck disability index is a questionnaire designed to give us information as to how neck pain has affected the ability to manage in everyday life. It consists of ten sections each of them descripes one of daily activity and graded from zero to five the higher the total score the more severity of disability. The sections are pain intensity, personal care , lifting, reading , headache, concentration, work, driving, sleaping, recreation . its developed by Vernon,H .\& Mior,S . (1991)
次要结局
- Assesment of bony union(1year)
