Osteoid osteoma and HIFU Treatment




An osteoid osteoma is a small benign bone tumor that is found most commonly in the vertebra and long bones, such as the femur and tibia. It consists of a nidus, or a core of growing cells, surrounded by a thick bony shell.

Patients with osteoid osteoma experience pain that worsens at night. The cause of osteoid osteomas is not known. Osteoid osteomas affect anywhere from 10 to 40 individuals per 100,000, comprising 12% of benign bone tumors and 3% of all bone tumors. They are three times more common in males than in females, and the majority are found in children and adults up to 24 years old.

In many cases, osteoid osteomas disappear within 3 years, and the pain associated with them can be managed with non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen. For cases where pain is severe or does not respond to NSAIDs, treatment options include surgery and radiofrequency ablation.

Focused Ultrasound Treatment
Focused ultrasound has the potential to offer a completely noninvasive method of ablation. Instead of making an incision and inserting probes, the physician, guided by ultrasound or magnetic resonance imaging, directs a focused beam of acoustic energy toward the nidus. This beam heats and destroys the osteoid osteoma without
damaging nearby tissues or structures.

As a potentially noninvasive treatment, focused ultrasound may offer benefits including:

*more precise targeting of the nidus by ultrasound or magnetic resonance     imaging, reducing the risk for damage to surrounding bone and tissue;

*shorter treatment duration;

*lower risk for complications such as infection; and


*shorter recovery time, with the patient often returning to work and other   activities the following day.
