Abstract：Objective To assess the clinical effects of radiofrequency ablation ( RFA ) combined with percutaneous vertebroplasty ( PVP ) for the treatment of spine metastases. Methods During the period from June 2012 to October 2016, a total of 35 consecutive patients with spine metastases were treated with combination of RFA and PVP in Cancer Hospital, Chinese Academy of Medical Sciences. A total of 26 cases with 27 vertebras who had complete medical information were enrolled in this study. The pain relief was evaluated according to the visual analogue scale ( VAS ) scoring system. The height restoration of anterior border of injured vertebra was evaluated based on the X-ray film. The data were analyzed by using paired-samples t test. Results With a mean follow-up of 11.8 months ( range: 1 - 33 months ), all the patients felt lumbodynia relieved. The effectiveness was 92%. The good and excellent rate was 87%. The preoperative and postoperative VAS scores were 5.73 ± 2.55 and 2.58 ± 1.84 respectively ( P < 0.05 ). Good height restoration of anterior border of injured vertebra was observed on the X-ray film, and there were statistically significant differences when compared the preoperative value ( P < 0.05 ). Conclusions Good pain relief and improvement of quality of life could be observed in the treatment of spine metastases with combination of RFA and PVP, which is an effective method.
