Abstract: STUDY DESIGN: A prospective study on 24 patients with spinal osteoid osteoma treated with radiofrequency ablation (RFA). OBJECTIVE: To determine if and when computed tomography (CT)-guided RFA is a safe and effective treatment for spinal osteoid osteomas. SUMMARY OF BACKGROUND DATA: Surgery has been considered the standard treatment for spinal osteoid osteomas. Surgery may cause spinal instability, infection, and nervous injury. We evaluated CT-guided RFA as an alternative treatment. METHODS: A total of 28 RFA procedures in 24 patients with spinal osteoid osteoma were performed, using a 5-mm noncooled electrode. Clinical symptoms and spinal deformity were evaluated before and after the procedure. Unsuccessful treatment was defined as the presence of residual or recurrent symptoms. The mean follow-up was 72 months (range: 9-142 months). RESULTS: Nineteen (79%) patients were successfully treated after 1 RFA, and all except one after repeat RFA. One patient with nerve root compression needed further surgery. No complications were observed. Spinal deformity persisted in 3 of 7 patients after successful RFA. CONCLUSION: CT-guided RFA is a safe and effective treatment for spinal osteoid osteoma. Surgery should be reserved for lesions causing nerve root compression.
