Twenty-three adults with fractures of the odontoid process are reviewed. Te possible reasons for the high rate of non-union in reported series are considered: these include the type of fracture, its displacement, the presence of a gap at the fracture site, imperfect reduction and inadequate immobilisation. Type 2 fractures (at the base of the odontoid process) are the commonest and also the most liable to nonunion. In their treatment, reduction is important; as seen in the lateral radiograph at least two-thirds of the fracture surfaces should be in contact. Skull traction is not advised and halo-cast fixation is the treatment of choice; with this method 87.5 per cent of recent odontoid fractures united.
对23例齿突骨折的成年人进行了回顾性研究。分析了既往报道中不愈合率高的可能原因：包括骨折类型、移位情况、骨折部位间隙的存在、复位不佳及固定不充分。2型骨折（齿突基底部）最为常见，也最易发生不愈合。在其治疗中，复位很重要；从侧位X线片看，至少三分之二的骨折面应接触。不建议使用颅骨牵引，头环石膏固定是首选治疗方法；采用这种方法，近期齿突骨折的愈合率为87.5%。
