Objective:To evaluate the application and efficacy of direct anterior fixation of odontoid fractures with hollow screw.Methods:Eighteen patients with odontoid fractures

13 males and 5 females

and 11 with type Ⅱ fractures and 7 with type Ⅲ fractures

including 5 cases with shallow type Ⅲ fractures

according to Anderson’s classification system

underwent percutaneous anterior odontoid screw fixation with one screw plant.The clinical examinations were carried out to observe the therapeutic effects through the follow-up.Results:The patients were followed up for 9 months(6～24 months).Fracture union was noted in all patients.There was no sign of rupture

loosing or falling of the hollowscrew.Previous symptoms disappeared completely in 15 cases.A majority of the patients resumed an excellent cervical motion.Conclusion:This method is a prevalent method with the advantages of convenient procedure

less injury and complication

rapid recovery

and a strong inner fixation.In this way
