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.
