ABSTRACT
BACKGROUND:Percutaneous vertebroplasty is mainly used to treat senile osteoporotic compressive fractures,while for young patients,pedicle screw internal fixation is usually applied,but heavy trauma,nail broken,secondary surgery and other problems can be found occasionally.OBJECTIVE:To investigate the clinical efficacy of percutaneous vertebroplasty combined with granulated allogeneic bone grafting for thoracolumbar compressive fractures.METHODS:Twenty-one patients suffering thoracolumbar compressive fractures were recruited,and underwent percutaneous vertebroplasty combined with granulated allogeneic bone grafting.The Visual Analogue Scale scores,height ratio of fractured vertebrae and Cobb angle were detected before and after surgery.RESULTS AND CONCLUSION:(1) Compared with baseline,the Visual Analogue Scale scores were improved significantly at 1 day and 6 months postoperatively (P ＜ 0.05).(2) The height ratio of fractured vertebrae at 1 day and 6 months postoperatively was significantly higher than that before treatment (P ＜ 0.05).(3) The Cobb angle of fractured vertebrae at 1 day and 6 months postoperatively was significantly less than that before treatment (P ＜ 0.05).(4) The mean operation time was (52±12.3) minutes,and the mean blood loss was (11.5±1.5) mL.(5) These results suggest that percutaneous vertebroplasty combined with granulated allogeneic bone grafting can effectively restore the anterior fractured vertebral height,eliminate the cavity in the fractured vertebrae,renew the completeness and stabilization of the fractured vertebrae,which keep the spinal range of motion;therefore,it is a minimal invasive method in the treatment of thoracolumbar fractures.
ABSTRACT
Objective To investigate the value of radionuclide bone imaging in the diagnosis and localization of osteoporotic vertebral compressive fracture.Methods Percutaneous vertebroplasty was applied to 40 patients suffering from osteoporotic vertebral compressive fracture.Responsible vertebral bodys located according to the radionuclide bone imaging was involved as bone scan group,and responsible vertebral bodys located according to the physical examination,X-ray,CT and MRI as standard group.Then the Kappa test was carried out.Result In bone scan group,56 vertebrae were located by radionuclide bone imaging,and in standard group,58 vertebrae were located by X-ray,54 vertebrae by CT and 52 vertebrae by MRI.The Kappa value was 0.76,indicating essentially excellent agreement and statistical significance.Conclusion Radionuclide bone imaging was another good choice for the diagnosis of osteoporotic vertebral compressive fracture.Especially for cases with contraindication of MRI,it offers a reliable choice.
