Aim. The contemporary use of ablation with radio-frequency and vertebroplasty is reported only by few studies with similar encouraging results.
Methods. Fourteen patients affected by lumbago or dorsalgy from vertebral metastases, have been selected from those patients referring to our center from March 2004 to October 2006. Patients have also been given a pain evaluation scale (verbal numerical scale) and an evaluation scale of their quality of life (SF-36). With the patient laying on the operating table, face down, the trocar was placed in the relative vertebral body in a trans-peduncular way. Once the tip was taken off, some small bone samples were taken for the bioptic exam and then for the ablation in radiofrequency; once this phase was over, the bone cement was prepared and then injected in the vertebral body.
Results. Of the 14 patients treated, all have reported a decrease of pain within one week. The average score in the verbal numeric scale decreased from 9.1±0.6/10 in the pre-operation period to 4.3±0.8/10 in the after operation period, with a statistically significant decrease (P<0.0001) of the pain perception .
In the same way, it was possible to record a statistically significant average improvement (P<0.0001) of the SF-36 scores, which went from an average value of 22.5±0.2 to 59.4±0.6. Similarly to the results of other works, 100% of the patients we treated had a drastic decrease of the pain perception in one week.
Conclusion. In literature there are few works on the association of radio frequencies and vertebroplasty in the treatment of vertebral metastases. However, as in our study, the results are very encouraging.
