title: Computed-tomography-guided percutaneous radiofrequency thermoablation for the treatment of osteoid osteoma-2 to 5 years follow-up.
abstract: The purpose of this study is to evaluate the efficacy of the computed tomography (CT)-guided percutaneous radiofrequency thermoablation (PRT) method with a minimum of 2 years follow-up. Twenty-eight patients who were followed for more than 2 years among 35 patients who underwent CT-guided PRT between April 1999 and May 2005 were included in this study. The mean age was 24.5 years (range 7-55 years) and the mean follow-up period was 40.1 months (range 24-66 months). With a radiofrequency electrode, the lesion was heated to 80 degrees C or 90 degrees C for 6.5 mins (range 3-9 mins). Clinical success was assessed at the out-patient clinic by symptoms and radiographs. Twenty-six patients (90%) experienced a total loss of symptoms and additional PRT also relieved the ongoing symptoms in all of the recurrent patients. PRT appears to be a safe and effective method for treating osteoid osteoma and is also effective in recurrent cases. This treatment modality is a minimally invasive procedure and is a good alternative to open surgical treatment.
