The clinical observation about percutaneous pedicle screws in treatment of Type A3 thoracolumbar fracture
Objective To compare the clinical effects of type A3 thoracolumbar fracture percutaneous pedicle screws fixation and open pedicle screw fixation．Methods 35 patients who had AO classification type A3 thoracolumbar spine fracture and without neurological symptoms in our department were enrolled in the research.18 patients in the observation group accepted short segment combined with intermediate percutaneous pedicle screws fixation;17 patients in the control group accepted open pedicle screw fixation. The VAS score、overall satisfaction、radiographic follow-up （VBI score、VBA score、Cobb’s Angle）were compared between two groups with the clinical effect. Results The average surgical duration in the observation group(percutaneous pedicle screws fixation) was (53±10) min, in the control group(open pedicle screw fixation) was (90±9) min（P＜0.05）.The bleeding during the operation of the observation group was (56±17) ml, the control group was (331±149) ml（P＜0.001）. There was no significant difference in the VBI score、VBA score and Cobb’s Angle at postoperative follow-up (P > 0.05 )． Conclusion This research is showing that the short segment combined with intermediate percutaneous pedicle screws fixation is a preferred treatment of Type A3 thoracolumbar spine fracture，which has the advantages of less bleeding, light pain, quick recovery and short surgical duration.
