Abstract:
Objective To explore the effects of radiofrequency ablation ( RFA) combined with percutaneous vertebroplasty ( PVP) by the injection of artificial bone for metastatic spinal tumor. Methods Fifty-eight patients with metastatic spinal tumors were divided into bone cement group 1 (n=12),bone cement group 2 (n=16), artificial bone group 1 (n=16), artificial bone group 2 (n=14). The patients in bone cement group were arranged RFA combined with PVP by injection of bone cement,and the artificial bone group were treated with RFA combined with PVP by injection of artificial bone. The vertebral body modality,fractures, and visual analogue scale ( VAS) ,spinal ODI score were compared before operation,1 week,1,3,6,9,12 months of after operation. Results There were 12 patients (42. 9%) with vertebral body deformation in bone cement group,which was more than those in artificial group (6. 7%) (χ2 =8. 4768,P=0. 0036). The VAS or DOI score decreased after operation than those pre-operation in the 4 groups (P<0. 01),but increased in bone cement group after operation of 6, 9 and 12 months than those in artificial group (P<0. 05). Conclusion The combination of RFA and PVP by injection of bone cement or artificial bone is effective to metastatic spinal tumors. The effects of PVP injection with artificial bone maintains longer duration compared to bone cement.
