English Abstract:

  【Abstract】 Objectives: To investigate the clinical value of percutaneous curved vertebroplasty(PCVP) in the treatment of osteoporotic thoracolumbar vertebral compressive fractures. Methods: 96 patients(128 vertebrae) suffering from osteoporotic thoracolumbar vertebral compressive fractures were divided into three groups: curved group(36 patients, 43 vertebrae), unilateral group(32 patients, 42 vertebrae) and bilateral group(28 patients, 43 vertebrae). There was no significant difference among the three groups in gender, age, bone mineral density and diseased vertebral segment(P>0.05). The average operation time, X-ray exposure, bone cement injection volume, bone cement leakage rate were recored and compared. The VAS scores were compared at preoperation, 24 hours and 3 months after operation. Results: The operation time of curved group and unilateral group were less than that of bilateral group, the differences were statistically significant(P<0.05). But there was no statistical difference between curved group and unilateral group(P>0.05). The X-ray exposure of curved group and unilateral group were less than that of bilateral group, the differences were statistically significant(P<0.05). But there was no statistical difference between curved group and unilateral group(P>0.05). As for the bone cement injection volume, bilateral group(6.2±1.5ml) had the highest volume and following was curved group(4.5±1.3ml), and the least was unilateral group(3.4±1.2ml), the differences were statistically significant among the three groups(P<0.05). As for the bone cement leakage rate, unilateral group(28.6%, 12/42) was the most and following was bilateral group(18.6%, 8/43), and the least was curved group(9.3%, 4/43), the differences were statistically significant among the three groups(P<0.05). All the patients in the three groups obtained obvious pain relief. The average VAS score at 24 hours and 3 months after operation was lower than that at preoperation(P<0.05). But there was no statistical difference in the average VAS score between 24 hours and 3 months after operation(P>0.05), and there were no statistical differences among the three groups(P>0.05). Conclusions: Percutaneous curved vertebroplasty has the advantage of easy operation, shorter operation time, less X-ray exposure, less trauma and complications, which is a minimal invasive method for osteoporotic thoracolumbar vertebral fractures.
