Abstract：Objective To compare and analyze clinical outcomes of percutaneous and open pedicle screw internal ifxation of single segment thoracolumbar fractures without neurologic symptoms.Methods One hundred and two patients with thoracolumbar fractures without neurologic symptoms underwent either percutaneous pedicle screw ifxation ( PF,n=58 ) or open pedicle screw ifxation ( OF,n=44 ) between January 2011 and January 2014. Perioperative related indicators, radiographs indicators, visual analog scales ( VAS ), oswestry dysfunction index ( ODI ), middle and long-term efifcacy were analyzed.Results PF group: incision length ( mean, 6.6±0.8 cm ), blood loss ( mean, 55± 27.6 ml ), hospital stay ( mean, 7.9±2.6 days ), getting out-of-bed time ( mean, 4.3±1.7 days ). OF group: incision length ( mean, 15.1±2.7 cm ), blood loss ( mean, 213±54.5 ml ), hospital stay ( mean, 16±5.2 days ), getting out-of-bed time ( mean, 10.5±3.2 days ). There were signiifcant differences in 2 groups (P<0.05 ). PF results were superior to OF group. No signiifcant differences existed in operation time, screw accuracy, recovery of vertebral body height and ODI 6 months, 12 months postoperatively in 2 groups (P>0.05 ).Conclusions Percutaneous pedicle screw internal ifxation as a good minimally invasive surgery method has the advantages of small trauma, earlier recovery and confirmed efifcacy. Clinical outcomes in middle and long-term of PF are similar with OF.
