title: Radiofrequency ablation of bone tumours.
abstract: The indications for radiofrequency bone ablation in the case of benign tumours (osteoid osteoma, osteoblastoma) are curative, whereas for bone metastases, the prime aim is palliative analgesia. The failure rate for osteoid osteomas is low (<15%), and 70 to 90% of patients with metastases experience considerable relief, but if the treatment fails, it can be offered again. In the spine, heating can damage neighboring nerve structures, which means they need to be protected (CO(2) dissection). Radiofrequency ablation may be combined with an injection of cement. The osteonecrosis resulting from heating is painful and justifies performing the procedure under general anesthesia.
