English Abstract:

  【Abstract】　Objective：To evaluate the short-term outcome of percutaneous kyphoplasty for traumatic thoracolumbar vertebral compression fractures.Method：A total of 36 vertebras from 36 cases（11 males and 25 females） with the mean age of 54.5 years old（range，50 to 61 years old） suffering from traumatic thoracolumbar vertebral compression fractures experienced percutaneous kyphoplasty under fluorescence.Each fractured vertebra was filled with MIIGX3 artificial bone.The clinical outcome was evaluated by visual analog scale（VAS） and other parameters including use of pain-killer scale，the Cobb′s angle and the height of vertebral bodies.Result：All surgery were completed successfully，mean operative time was 32.5min/vertebrae，mean bleeding was 38.5min/vertebra，mean filling amount of MIIGX3 was 5.0ml/vertebrae，without pulmonary embolism，MIIGX3 leakage and other complication occurred.Each patient had back pain relieved postoperatively.The followed up was 6 months to 30 months.The VAS score improved from preoperative 8.5±0.8 to postoperative 2.2±0.8 and 2.5±0.8 for final follow up（P<0.01）.The use of pain-killer scale improved from preoperative 1.8±0.6 to postoperative 0.2±0.6 and 0.3±0.5 for final follow up（P<0.01）.The mean height of the anterior vertebral body increased from preoperative 21.5±3.1mm to postoperative 24.6±2.8mm and 24.4±2.6mm for final follow-up（P<0.01）.The median vertebral body increased from 20.3±2.9mm to 24.3±2.1mm，and 24.1±2.5mm for final follow-up（P<0.01）.The mean Cobb′s angle for kyphosis increased from 18.5°±4.5° to 13.5°±3.5°，and 14.0°±4.5° for final follow-up（P<0.01）.After 3 months follow-up，all 36 cases regained routine daily activity.Conclusion：Kyphoplasty as a reliable treatment for traumatic thoracolumbar vertebral compression fracture has the advantage of vertebra height restoration and definite pain relief.
