ABSTRACT Progress in medical imaging has improved recognition and management of osteoid osteoma. The purpose of this study was to assess the efficacy of computed tomography (CT)-guided percutaneous thermal ablation and discuss the advantages and disadvantages.
We reviewed retrospectively 33 consecutive patients with osteoid osteoma who had undergone CT-guided radiofrequency ablation. The diagnosis was established on the basis of the clinical presentation and pathognomonic radiographic findings (CT and bone scintigram) without histological proof. We recorded patient age and gender, tumor location, clinical signs and duration, imaging findings, duration of the ablation procedure, type of anesthesia, hospital stay, and complications. We evaluated their effect on final outcome.
Weight-bearing was possible in all patients with a lesion of the lower limb a few hours after surgery. Patients resumed their normal activities in 24-48 hours. Pain resolved immediately after radiofrequency ablation in 26 patients and limping, when present, disappeared within 24 hours. At mean follow-up of 34 months (minimum 12 months) there was one case of recurrent pain. Clinical cure was confirmed by CT and bone scintigraphy in twelve patients.
This precise and minimally invasive method is an effective and safe way to reduce healthcare expenditures. It can be recommended as the primary treatment for osteoid osteoma.

    ABSTRACT: We aimed to evaluate the effectiveness of image-guided laser ablation for the treatment of osteoid osteomas in pediatric patients. From June 1994 to June 2006, 68 patients aged 3 to 18 years (mean age, 12.1 +/- 4.2 years) with a diagnosis of osteoid osteoma underwent laser ablation in our department. Among them, 3 patients had prior unsuccessful attempt of surgical resection. Procedures were performed under spinal or general anesthesia with combined computed tomographic and fluoroscopic guidance. An 18-gauge needle was placed in the nidus after bone drilling when required, and an optical fiber was inserted through it. An average energy of 1200 J was delivered using an infrared diode laser generator. Patients were discharged the next day and followed up with assessment of pain, medication intakes, and potential complications. Clinical success was defined by complete pain relief without need for medication intake. Technical success was achieved in all but 1 of our first patients, which was subsequently treated by percutaneous resection. Overall clinical success was 98%. Primary clinical success was obtained in 60 patients (88%). In 7 patients, recurrence of symptoms at 4 to 27 months from the initial procedure was managed by repeat laser ablation, resulting in secondary success (10%). No complications related to the procedure were observed. Follow-up ranged 16 to 146 months (mean, 83 months). Currently, image-guided laser ablation is a safe and effective procedure that can be proposed as the mainstay treatment of osteoid osteomas in pediatrics. Therapeutic case series study level IV.

    ABSTRACT: Introduction Osteoid osteoma is a painful, benign bone tumor that mainly affects young people. Thermocoagulation is one of the recommended percutaneous treatment methods. This study sought to assess its efficacy and identify risk factors for osteoma recurrence. Methods Results were analyzed retrospectively for a group of 87 patients treated by thermocoagulation between 2002 and 2011. The recurrence rate was calculated and analyzed relative to patient and tumor characteristics. The treatment efficacy was determined and methods to prevent complications were analyzed. Results The mean follow-up time was 34 months. The average patient age was 23 years. There were seven complications including three patients with delayed wound healing, mainly at tibial sites. The recurrence rate was 10.4%. The success rate for first-line treatment was 89.6% and it was 97.5% for second-line treatment. Analysis of patient characteristics and tumor locations revealed no risk factors for recurrence. Conclusion Percutaneous thermocoagulation is a reliable and effective technique that provides fast, long-lasting pain relief. However recurrence can occur even after the nidus is completely resected. These recurrences can be effectively managed by repeat treatment. Recent technical improvements have reduced the risk of thermocoagulation-related complications. Level of evidence IV.
