Radiographic Analysis of the Dose of Bone Cement in Percutaneous Vertebroplasty and Kyphoplasty in Spinal Fractures

Objective: To explore a best does(method, standard and accurate calculation) of bone cement in PKP, based on the CT and MRI image data of thoracolumbar vertebrae with new compression fracture. Methods: 42 new compression fracture patients with thoracolumbar vertebrae injury underwent PKP and examined by CT and MRI before surgery no more than 1 week. Retrospectively analyzed the image data and compared the statistical image data followed a variety of reconstruction. Results: Of 42 cases, new compression fracture located in the T10(n=2), T11(n=5), T12(n=9), L1(n=11), L2(n=7), L3(n=5), L4(n=3). The average fracture compression rate of bone cement in PKP ranged from 1.6 to 6.3ml. Conclusion: It is practicable to predict the best dose of bone cement in PKP that by reprocessing the image of preoperative CT and MRI, which can make the treatment more effective, at the same time, the interrelated complication can be avoided.
