[Method]: Thirty three cases of lower cervical fracture-dislocation were received the treatment by a new type of cervical traction and reduction apparatus which is developed by the compositon of skull traction tong, slider, spring, ratchet wheel, bracket, rail and baseplate.After reduction then flexible and reasonable operative approaches should be adopted to treat fracture and dislocation of cervical spine according to the patients condition, and its follow-up was performed for observation of treatment effects. [Results]: This new skull traction device can be increase weight instantly, predetermined length and traction angle adjustable.33 patients were all successful reducted, no case of nerve injury was aggravated, without a traction fixed screw loosed or prolapsed was found. The average traction weight,time and angle was 25.6kg(10kg～60kg)，23.5min(3～75min) and 3.5 degrees（5～35 degrees）,respectively. The follow-up lasted for average 37 months(20～42 months) and all case got a satisfactory outcome of follow-up. [Conclusion]: The new traction device for lower cervical fracture-dislocation have the characteristics of simple ,practical, safe and efficient and have great clinical applications . 第一作者简介：男(1986一)，
