Résumé
To compare the clinical application in the percutaneous vertebroplasty under the guidance of one or two C-arm fluoroscopes. One hundred forty three elderly patients with Osteoporotic vertebral compression fractures [OVCFs] underwent percutaneous vertebroplasty under the guidance of one or two C-arm fluoroscopes. The number of pulsed imagings, the time of operation and the incidence of cement leakage were recorded. The average number of pulsed imagings was 16.00 +/- 1.58 vs 13.07 +/- 2.00 per patient under the guidance of one vs two C-arm fluoroscopes. The average time of operation was 48.42 +/- 5.00 minutes vs 39.70 +/- 7.42 minutes per patient under the guidance of one vs two C-arm fluoroscopes. The incidence of cement leakage was 20% vs 15.7% of the patients under the guidance of one vs two C-arm fluoroscopes. The differences in the number of pulsed imagings and the time of operation were statistically significant. The difference in incidence of cement leakage was not statistically significant. The two-fluoroscopic technique reduce the labor cost, the radiation, the time of operation and the operation risk
