On 27 November 2020, the US Food and Drug Administration (FDA) approved the Sonalleve MR-HIFU system (Profound Medical Inc.) for the treatment of osteoid osteoma in the extremities.
MR-guided High Intensity Focused Ultrasound (MR-HIFU) treatment is an image guided technique combining high intensity focused ultrasound ablation with real time monitoring of temperature change during the sonication.
The clinical results support the probable benefit of Sonalleve MR-HIFU system for the ablation of painful osteoid osteoma. Efficacy was evaluated in a study of nine patients treated with MR-HIFU, without technical difficulties or serious adverse events. There was a statistically significant decrease in their pain scores within 4 weeks of treatment. No pain medication usage was achieved in 8 of 9 patients after 4 weeks.
The device should not be used under certain conditions. For full information including warnings and precautions, view the Summary of Safety and Probable Benefit Document for the Sonalleve MR-HIFU system that is available here.
Healthcare professionals should report all serious adverse events suspected to be associated with the use of any medicine and device to FDA’s MedWatch Reporting System.
