Objective To explore the efficacy of C1-C2 pedicle screw fixation and non-fusion for fresh odontoid fractures. Methods 28 patients ( 17 males and 11 females, aged less than 50 years ) with fresh type ?odontoid fractures who had been hospitalized during the period of January 2007 to February 2010 received C1-C2 pediele screw fixation and non-fusion. The screws were removed after fractures were cured to observe the rotation function of the cervical spine. Results All the patients were followed up for 6 to 24 months, with an average of 14 months. CT scans showed fracture healing occurred from 3 to 6 months after surgery in all the patients, with an average of 5 months. Cervical function was assessed after the screws were removed. The rotation function of the cervical spine was significantly reduced after surgery, but it returned to near normal 3 months after functional exercises and physical therapy. Conclusions Atlantoaxial posterior pedicle screw fixation without atlantoaxial fusion has a stable three-dimensional fixing effects and meets the need of healing in younger patients with type Ⅱ fresh odontoid fractures. Screw removal after fracture healing is beneficial for the recovery of upper cervical spine rotation. Key words: Type Ⅱ fresh odontoid fractures; Non-fusion; Pedicle screw
