[Objective] To explore the value of real-time navigation in the treatment of thoracolumbar fracture . [Method ] March 2003 to December 2008 were treated 86 cases of thoracolumbar fracture patients were studied retrospectively 46 cases real-time navigation of pedicle screw fixation ( group A ) , 28 males , and 18 females, aged 18-56 years , mean 38 years , cause of injury : fall injury in 11 cases, 6 cases were injured by traffic accident in 29 cases ; injury site : T118 cases , T1214 cases , L116 cases , L28 cases ; Macffee classification, flexion compression in 19 cases, 18 cases of burst fracture , Chance fracture in 3 cases , six cases of fracture and dislocation . 40 cases of traditional X-ray method pedicle screw fixation (B group) , 26 males and 14 females , aged 17 to 55 years old , an average of 37 years of age , cause of injury : fall injury cases , injured six cases traffic accident in 26 cases ; injury site : T116 cases , T1213 cases , cases of L112 , L29 cases ; flexion compression by Macffee segment 17 cases , 15 cases of burst , Chance fracture in 2 cases, six cases of fracture and dislocation . Evaluation by image analysis technique , the the pedicle level after CT scan , operative time, amount of bleeding and clinical outcomes . [ Results ] 1.A group pedicle screw placement accuracy higher than in group B , Misplaced low ; 2.a B The mean operative time was 128 ± 38 min , 158 ± 42 minutes , both Compare P lt ; 0.05 ; a , B two sets of bleeding were 307 ± 60 ml , 412 ± 82 ml , both P lt ; 0.05 All patients were followed up for 12-18 months , X The line shows the vertebral height restoration extent was no significant difference between the two groups . [Conclusion] The treatment of thoracolumbar fracture patients should adhere to the principle of individualization , strict control of posterior decompression and internal fixation of surgical indications ; thoracolumbar fractures of the spinal column damage , posterior decompression laminectomy should not be as conventional surgery ; instantaneous tracking of navigation , real-time monitoring, precision-guided within the plant , to enable the operator to image , multi-dimensional , real-time sense of strong, avoid the error caused by the thoracolumbar fracture patients with postural change , navigation is an ideal within the plant boot mode ; real-time navigation pedicle screw fixation in the treatment of thoracolumbar fractures , shorten the operation time, reduce the amount of bleeding , rapid postoperative recovery , through a small trauma to achieve better therapeutic effect , the clinical application of the concept of minimally invasive spine surgery .
