Computed tomography-guided radiofrequency ablation of osteoid osteomas.
OBJECTIVE
To report on 14 patients with osteoid osteomas treated by computed tomography-guided radiofrequency ablation.


METHODS
Nine males and 5 females aged 13 to 45 (mean, 25) years with osteoid osteomas were included. The proximal tibia was the commonest site involved. A bipolar 18-gauge radiofrequency probe with a 9- mm active tip was used. A 4.5-mm hollow drill was introduced into the nidus. Energy application was started at 2 W and increased to a maximum of 5 W. Heat was applied for 4 to 6 minutes at 90 degrees Celsius.


RESULTS
12 (86%) of the 14 patients had prompt pain relief; the remaining 2 underwent a repeat ablation. After a mean follow-up period of 19 (range, 9-25) months, no patient had pain recurrence.


CONCLUSIONS
Radiofrequency ablation is a minimally invasive and cost-effective treatment for osteoid osteomas.
