[Osteoid osteoma and radiofrequency]

Osteoid osteoma and radiofrequency Osteoid osteoma relates to a benign skeletal neoplasm, smaller than 2 cm in diameter, composed of osteoid, highly vascularized connective tissue and surrounded by a ring of bone sclerosis. Its aetiology remains unknown. It affects twice more males than female patients and occurs usually between 5 and 40 years old. Long bones and spine are the most involved areas but the whole skeleton can be involved. Clinical manifestations can include local pain (increased at night and decreased by activity) and relief with salicylates administration. CT guided radiofrequency ablation of osteoid osteoma is in comparison to surgery less invasive, time saving and economic technique with excellent long term results.
