Abstract：[Objective]To sum up the experience, technique and initially clinical and radiographic results for the treatment of upper unstable thoracic trauma with pedicle screw technique, and try to find out the reasons for complications.[Method]The clinical and followup data of 49 cases of upper unstable thoracic trauma treated form Jan. 1998 to Jan. 2004 with pedicle screws and Rod system fixation were summarized. All the data were analyzed with NASS software in t and x2 test. [Result]This technique significantly resumed the anatomy construction of the injured upper thoracic column from subluxation and kyphotic deformity ( P <0.05 ) except the burst fracture type. The inhospital time and keepinbed time were reduced and postoperative kyphosis occurrence, complications and scoliosis were prevented. To measure the anatomy construction of the pedicles with CT preoperatively was one of the most important thing for using matched screws to fix pedicles.[Conclusion]The pedicle screw combined with Rod system is a reliable, safe and effective technique for treating upper unstable thoracic trauma, and it could be considered as an efficient alternative to previously reported techniques. ......
