Abstract:In recent years, minimally invasive techniques, such as percutaneous cementoplasty, percutaneous cryoablation, magnetic-resonance-guided focused ultrasound surgery, radiofrequency ablation, microwave ablation, radioactive particle implantation, transcatheter arterial embolization and irreversible electroporation et al, play more and more important roles in the treatments of bone metastasis. Compare with traditional therapies like radiotherapy, drugs and surgery, the better efficacy and security of minimally invasive techniques have been demonstrated by voluminous animal experiments and clinical trials. However, the clinical application of minimally invasive techniques have still some controversial issues.
