Purpose : follow-up study of patients with fractures of the thoracic and lumbar vertebral body treatment using minimally invasive percutaneous Pillar implant , assessing the radiological results discussed Pillar treatment of thoracolumbar compression fracture indications , methods, and clinical efficacy . Methods: From June 2009 - December application to the treatment of thoracolumbar vertebral compression fractures in 45 patients with implanted minimally invasive percutaneous Pillar vertebral body . Follow-up time of 6 months -18 months , an average of 12 months ; 33 cases of trauma , chronic injury , 12 cases ; age 40-82 years, mean 58 years of age . There were 24 males and 21 females . Simply a vertebral fracture : T 11 2 Li , T 12 8 Li , L 1 < / sub> 20 cases, L 2 < / sub> 3 Li , L 3 2 Li L 4 < / sub > 2 cases , L 5 2 cases, both of vertebral fracture in 6 cases , a total of 51 vertebral fractures , T 11 vertebrae 3 , T 12 vertebral 8 , L 1 vertebrae 25 , L vertebral 2 4 L 3 of vertebral 6 L 4 vertebrae 3 , L 5 < / sub > two vertebral ; 8 vertebral single gold Pillar , 43 vertebrae to double gold Pillar, shared 94 Pillar , Pillar of the models : 8 , 23 , 9 , 66 , 10, 4 , 11 a . All patients were first lumbar surgery , preoperative evaluation included history, physical examination , X-ray , CT and MRI examination . Measure around the edge of the vertebral height restoration preoperative Cobb 's angle changes ; VAS score function score observed minimally invasive percutaneous Pillar Interbody clinical efficacy for the treatment of thoracolumbar compression fracture . Results: The patients were successful surgery , postoperative incision infection . Operative time 35 - 65min , intraoperative blood loss :10- 50ml ; follow-up of 6 months -18 months , an average of 12 months . Vertebral height restoration by preoperative 49.51 ± 2.08% to postoperative 92.58 ± 3.24% , the height of the posterior margin recovery by 82.01 ± 3.18% of the preoperative to postoperative 93.35 ± 3.67%; spine Cobb's angle preoperative 26.18 o ± 3.25o recovery and postoperative 10.30o ± 2.95o ; VAS score surgery before 7-10 , an average of 8.25 points a week after surgery improved to 0-4 , with an average of 2.51 points . Conclusion: Minimally invasive percutaneous Pillar Interbody effective method of treatment of thoracolumbar compression fracture , postoperative pain significantly alleviate vertebra reduction and better features .
