Interventional radiology takes a large place in the treatment of bone metastases by numerous techniques, percutaneous or endovascular. Vertebroplasty appears actually as the most important technique for stabilisation of spine metastases as it induces satisfactory stabilisation of the vertebra and offer clear improvement of the quality of life. Due to the success of this technique cementoplasty of other bones, mainly pelvic girdle, largely develop. The heath due to the polymerisation of the cement induce carcinolytic effect but this effect is not as important as that can be created with radiofrequency destruction. This last technique appears actually as the most important development to destroy definitively some bone metastases and replace progressively alcoholic destruction of such lesions. Angiographic techniques appear more confidential but endovascular embolization is very useful to diminish the risk of surgical treatment of hyper vascular metastases. Chemoembolization is actually developped to associate the relief of pain induced by endovascular embolization and the carcinolytic effect obtained by local endovascular chemotherapy. All these techniques should develop largely during the next years and their efficacy and safety should improve largely by treating earlier the metastasis.
