Abstract :This study aims to evaluate the safety and efficacy of microwave ablation insert ignore into journalissuearticles values(MWA); in the treatment of painful extra-articular osteoid osteoma insert ignore into journalissuearticles values(OO); in long bones in a consecutive series of patients and to compare the technical and clinical success in terms of pain scores according to their location. A total of 23 patients who were diagnosed with OO in long bones and treated with MWA between January 1, 2016, and June 1, 2020 were enrolled in this study. Medical records and imaging were reviewed for age, gender, size of the radiolucent nidus and duration of pain. Patients were then categorized into three groups according to the location of nidus insert ignore into journalissuearticles values(pertrochanteric, metaphyseal or diaphyseal);. Operation length and technical and clinical success rates were compared. The number and severity of complications were also documented. Technical success was achieved in 100% of patients. Primary clinical success following MWA was 82.6%. The most common location was the pertrochanteric region insert ignore into journalissuearticles values(34.8%);. In comparing the pain scores with the locations of the lesions, no statistically significant difference was found between the first-day insert ignore into journalissuearticles values(p = 0.504); and first-week insert ignore into journalissuearticles values(p = 0.648);. However, significant difference was present between the first month insert ignore into journalissuearticles values(p = 0.016);, third month insert ignore into journalissuearticles values(p < 0.001); and sixth month insert ignore into journalissuearticles values(p = 0.001);. The statistically significant differences between the sites were due to the difference between the pertrochanteric and diaphyseal lesions. CT-guided percutaneous MWA is safe and effective in the treatment of OO located in long bones without any recurrence. However, management of pertrochanteric OOs requires specific expertise and follow up. Further studies are expected in the future to assess the long-term efficacy and safety of MWA for the treatment of OO, especially for cases in pertrochanteric locations of the femur, which have an increased risk of local recurrence.
