title: [Minimally invasive percutaneous pedicle screw fixation for the treatment of thoracolumbar fractures and posterior ligamentous complex injuries].
abstract: OBJECTIVE
  To evaluate the efficacy and safety of minimally invasive percutaneous pedicle screw for the management of neurologically intact patients  with thoracolumbar burst fractures and posterior ligamentous complex injuries.
  
  
  METHODS
  In the study, 35 patients were reviewed,including 20 males  and 15 females, with an average age of 34.1 years (18 to 52), and the mean follow-up for 25.8 months (24 to 36).
  
  
  RESULTS
  The duration of surgery was  (95.8±12.3) minutes and intraoperative blood loss was (83.0±40.7) mL. There were no major perioperative complications, with the exception of 2 patients  who developed a superficial wound infection. LKA and VBH were significantly improved immediately after surgery (P<0.001). No significant loss of  correction was observed in all the patients(P>0.05). Screw misplacement was observed in 9/140 (6.4%) and no patient showed neurological deficit as  a result of screw misplacement.
  
  
  CONCLUSIONS
  The minimally invasive percutaneous pedicle screw has a good clinical outcome in the treatment of  thoracolumbar burst fractures with posterior ligamentous complex injury, which could maintain the fracture reduction effectively, and minimize the iatrogenic  soft tissue injury.
