Conclusion
The classic treatment of the osteoid osteoma has been the surgery excision in block that, although highly effective, it is not exempt of diverse complications: relapse of the tumor, fractures, use of internal fixers, hospital stay and lingering functional recovery, among other described adverse effects. With percutaneous CT-guided resection complications have also been described: fractures, cutaneous necrosis and burns , intramuscular hematoma, paresis and osteomyelitis. We consider that percutaneous radiofrequency ablation of osteoid osteomas is a sure, effective technique and minimally invasive; and it should be considered as the election procedure in most of the patients with this type of tumor. The technique has only two contraindications: it cannot be used in patients with pacemakers and it should be avoided in those tumors that are located less than a centimeter away from any vascular and neurological structures of first order, since irreversible damages could take place. This happens, mainly, in the vertebral osteoid osteoma usually located in the posterior elements . The surgical treatment should be reserved for those cases in which the clinical and radiological diagnosis is not safe and when the technique is not indicated.
