Radiofrequency Ablation for Osteoid Osteoma


This minimally-invasive procedure is used to treat a rare type of benign tumor, called an osteoid osteoma, that forms within bone. This type of cancer most commonly occurs in the weight-bearing bones of children and young adults.


In preparation for the procedure, the patient is anesthetized and positioned. Using fluoroscopic guidance, the surgeon inserts a thin tube (called a canula) through the skin and pushes it through the soft tissue to reach the surface of the bone.

Accessing the Tumor

The surgeon inserts a thin drill through the cannula and carefully drills into the bone to reach the osteoma.


The surgeon carefully inserts a radiofrequency probe through the channel and guides it into the center of the osteoma. Once it is in position, the probe is heated for several minutes to destroy the tumor.

End of Procedure and Aftercare

When the procedure is complete, the probe and canula are withdrawn, and the insertion site is bandaged. Patients should notice a reduction in pain from the tumor within a few days, and may return to normal activities within a week. If the tumor is in a bone in the leg, the patient may be asked to refrain from stressful athletic activities for three months after the procedure.
