[Objective] To introduce the primary clinical result of applying a posterior nonfusion screw-rod fixation method for fresh type II and IIA Hangman fractures. [Method] From June 2010 to June 2017, selected 10 patients with type II or IIA of fresh Hangman fracture, including 6 cases with type II fracture and 4 cases with type IIA fracture, suffered from traffic accidents in 8 cases and falling accidents in 2 cases，admitted to hospital after average 4 days (ranging from 5h to 9d). 7 males and 3 females, aged from 28 to 62 years old, averaged 41 years old. Under the general anesthesia, all the 10 cases treated with C1-C3 screw-rods fixation but no bone grafting. When a solid bone union of the Hangman fracture was confirmed by CT scan, a second stage operation of the instruments removing was performed, and the recovery of cervical movement function was observed. [Result] All 10 cases got the Hangman fracture reduction and a successful posterior C1-C3 screw-rods fixation, and no neural or vascular injury was observed. The cases were followed up from 6 to 12 months after the first stage operation, and all the patients had a solid bone union on CT scans. After instruments remove out, the cervical spine movement function almost restored to normal in all cases within a 6 to 12 months follow up. [Conclusion] For fresh type II and IIA Hangman fracture, applying a first stage posterior screw-rods fixation and a second stage instruments removing treatment method can not only reset the fracture satisfactorily, but also reserve movement function of the cervical spine with no residuary instruments, which is a compensatory method for anterior or posterior fixation and fusion techniques.
