Abstract Objective To compare outcomes between percutaneous and open pedicle screw fixation across injured veatebrae in the treatment of thoracolumbar fracture. Methods 36 patients with thoracolumbar fracture who were treated with pedicle screw fixation across injured veatebrae were retrospectively reviewed.There were 26 males and 10 females，at the age of 19～63 years old，averagely (43.1±10.4) years old.16 patients underwent percutaneous pedicle screw fixation, and 20 patients underwent open pedicle screw fixation.Intraoperative blood loss，operation time，visual analogue scale(VAS)，Oswestry disability index(ODI) scores，Cobb angel，anterior height of fractured vertebrae were measured.Results Blood loss in the percutaneous group was significantly less than in the open group(P＜0.05).VAS，ODI scores in the percutaneous group were significantly lower than in the open group in every follow-up time after surgery(P＜0.05).There was no significant difference in Cobb angel，anterior height of fractured vertebrae during follow-up between two groups(P＞0.05).Conclusion Compared with open surgery，percutaneous pedicle screw fixation across injured veatebrae in the treatment of thoracolumbar fracture resulted in reduced injury，provided earlier recovery and better outcomes.

Key words： percutaneous pedicle screw thoracolumbar fracture internal fixation
