[Direct fixation of odontoid process base fractures]

Fractures of the base of odontoid process are serious spinal injuries. Their treatment still remains controversial. External rigid immobilisation is the way of conservative healing. Operations by posterior approach: posterior atlantoaxial fixation, atlantoaxial transarticular screw fixation or even occipitocervical fixation limit range of head motion. Direct odontoid screw fixation preserves normal motion of C1-C2 junction. Success of this method depends on proper patients selection. The authors present description of surgical technique based on literature review and their own experience. The authors perform odontoid fixation by means of single cannulated cancellous screw guided by K-wire. This wire provides stability of broken odontoid process during procedure of screw insertion. Old fracture--1 case in author's experience--has been curetted before fixation. The authors reviewed clinical efficacity and results of direct odontoid screw fixation published in current literature.
