Purpose: To present the clinical outcome of computed tomography (CT) guided radiofrequency ablation (RFA) for osteoid osteoma.
Materials and Methods: Thirty-one patients (M:F = 23:8, mean age: 20 years, range: 4?54 years) who underwent RFA for clinically suspected osteoid osteoma from May 2004 to December 2013 were retrospectively reviewed. RFA was done in all cases under CT guidance by one of three radiologists in our department. Electronic medical records and images were retrospectively reviewed in all patients.
Results: Lesions were located in femur (n = 20), tibia (n = 5), fibula (n = 2), humerus (n = 3), talus (n = 2), and calcaneus (n = 1). On discharge, 27 of 33 cases showed complete remission of pain (82%). One major complication (compartment syndrome) and 2 minor complications (reactive synovitis, minimal skin burn at electrode insertion site) were observed. On the last follow-up (0?78 months, mean: 12.6 months) 27 of 33 cases were successfully treated (82%) and had no more complaints. 3 cases presented remaining pain (9%). In 3 cases relapse occurred (9%) and RFA was repeated in 1 case. The repeated treatment was successful.
Conclusion: CT-guided RFA is an effective method for the treatment of osteoid osteoma.
