Role of percutaneous computed tomography-guided radiofrequency ablation in treatment of osteoid osteoma

AIM: The aim of the study was to evaluate efficacy of percutaneous computed tomography (CT)-guided radiofrequency ablation (RFA) of nidus in osteoid osteoma (OO). MATERIALS AND METHODS: RFA was performed on fifty patients with clinically and radiologically diagnosed OO. RFA was done in the department of radio-diagnosis in our institute (a tertiary care providing institute in Ahmedabad, Western India). Ablation was performed by putting at an electrode tip (3–5 mm) into nidus under CT guidance with targeted temperature of 90°C for 3 min. RESULTS: All procedures were technically successful. No immediate major or minor complications were observed. Complete clinical success was achieved in 46 patients. Only four patients required second intervention. CONCLUSION: Our experience indicates a 98% success rate. No major complications were noted.
