Radiofrequency treatment. 
This article discusses radiofrequency energy as a treatment of musculoskeletal tumors,focusing on osteoid osteomas.  The technique has also been applied to a number of different primary musculoskeletal tumors and is increasingly being used as a palliative method in the management of painful skeletal metastases.  Radiofrequency treatment of musculoskeletal tumors can be of great clinical value.  When the low-power, highly limited methods are applied to small tumors such as osteoid osteomas, the technique is effective and exceptionally safe.  Creation of larger thermal lesions, however, can be accompanied by significant risks, and the risk-to-benefit ratio should be carefully considered before undertaking such a treatment.
