Fifteen percent of cervical spine fractures involve the odontoid process. Most odontoid fractures can be classified as Types I through III according to the scheme developed by Anderson and D'Alonzo. We report a case of a vertically oriented fracture through the odontoid process that does not fit into any of these categories. Only two such cases have been described in the literature. Our patient is an 18-year-old man who sustained an axial loading injury to his cervical spine. Plain lateral cervical tomography and computed tomography were performed to characterize the fracture and to evaluate the instability. The patient was placed in a rigid orthosis for 12 weeks, and at 6-month follow-up, he had full range of motion and showed no evidence of abnormal movement, as revealed by flexion-extension studies. This case demonstrates the shortcomings of the current classification system for odontoid fractures and value of plain tomography and computed tomography in evaluating odontoid fractures.
15%的颈椎骨折累及齿突。根据安德森和达隆佐制定的方案，大多数齿突骨折可分为I型至III型。我们报告一例通过齿突的垂直方向骨折，该骨折不属于上述任何类别。文献中仅描述过两例此类病例。我们的患者是一名18岁男性，其颈椎遭受轴向负荷损伤。进行了颈椎侧位平片断层扫描和计算机断层扫描以明确骨折特征并评估稳定性。患者佩戴硬质矫形器12周，在6个月的随访中，他的活动范围正常，屈伸研究显示无异常活动迹象。该病例证明了当前齿突骨折分类系统的不足以及平片断层扫描和计算机断层扫描在评估齿突骨折中的价值。
