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.
