A method of percutaneous vertebroplasty under the guidance of two C-arm fluoroscopes

Objective: to compare the clinical application in the percutaneous vertebroplasty under the guidance of one or two c-arm fluoroscopes. methods: 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. results: 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. conclusion: the two-fluoroscopic technique reduce the labor cost, the radiation, the time of operation and the operation risk.
