Experience with a Novel Thermoablative Procedure for Recurrent Osteoid Osteoma

Thermoablative procedures are minimally invasive procedures that induce coagulative necrosis in the tumor nidus using heat. This is especially useful in small tumors like osteoid osteoma where location of the tumor is rarely visible to naked eye. We present a report on the use of microwave ablation (MWA), as opposed to the popular radiofrequency ablation or surgical curettage, in the case of a recurrent osteoid osteoma in a young male. The MWA is dependent on the tissue resistance to the electromagnetic radiation, a resultant kinetic energy and a dipole moment produces high amount of heat causing heat necrosis of the tumor, acting on a larger area, causes faster coagulative necrosis and no recurrence.
