Percutaneous radiofrequency ablation (RFA) of osteoid osteomashas replaced surgical excision as the preferred method for treatment ofthese benign lesions, due to high effectiveness and low morbidity. BothRFA and cryoablation are safe and effective for palliation of pain dueto metastatic disease in patients who have failed conventional therapies.These image-guided treatments can be performed precisely, allowingsafe treatment of complex metastatic tumors. A single ablationtreatment is effective in most patients, is well tolerated, and provides along duration of pain relief.
