Objective:To analyze the curative effects and feasibility of the self regulating simple localizer through anterior approach for the treatment of odontoid fracture in adults. Methods:From June 2010 and December 2012,6 patients with odontoid fracture underwent an anterior operation using a single hollow screw located by the self regulating simple localizer. There were 4 males and 2 females,aged from 28 to 55 years old with an average of 39.1 years. The injuries were caused by traffic accidents in 4 cases and falling injury from high in 2 cases. According to the classification of Anderson,4 cases were typeⅡ and2 cases were simple type Ⅲ. All the patients underwent operations in 5 to7 days after injury with the mean of 5.9 days. None of the patients had a spinal cord injury. The safety and feasibility of the self made localizer were observed in follow up for fracture healing and clinical effects. Results:All the operations were successful with an average time of 50 min(ranged from 45 to 55min) and the mean bleeding volume was 25 ml(ranged from 20 to 30 ml). No injuries of esophagus,trachea or nerve were found. All the patients were followed up from 8 to 16 months and all fractures were obtained bone healing. The flexion extension radiograph showed a well stability of atlantoaxial joint in last followed up. Conclusion:The self regulating simple localizer is a minimally invasive,short time and safe method in treating odontoid fractures through anterior operation with hollow screw.It may be a reliable choice while without a professional localizer.
