Eighteen percent of acute cervical spine fractures involve the C-2 vertebra. The odontoid Type II fracture is the most common axis fracture and it is also the most difficult to treat. The degree of odontoid dislocation has been identified as the single most important fracture feature that helps separate those patients who have a high likelihood of healing with nonoperative therapy from those who are likely to fail nonoperative therapy and should be offered early surgical stabilization. The difference is statistically significant (p less than 0.001, x2 = 30.20). The present series includes 229 patients with acute axis fractures. Follow-up data were available in 92% of these patients, for a median duration of 4 years 9 months. Treatment guidelines and results are offered for each subtype of axis fracture based on this experience.
18%的急性颈椎骨折累及C-2椎体。齿状突II型骨折是最常见的枢椎骨折，也是最难治疗的骨折。齿状突脱位程度已被确定为最重要的骨折特征，它有助于区分哪些患者通过非手术治疗愈合可能性高，哪些患者非手术治疗可能失败而应尽早接受手术稳定治疗。差异具有统计学意义（p小于0.001，x2 = 30.20）。本系列包括229例急性枢椎骨折患者。其中92%的患者有随访数据，中位随访时间为4年9个月。基于这一经验，针对每种枢椎骨折亚型提供了治疗指南和结果。
