Osteoid Osteomas HIFU Clinical Trial

Comparative Treatment of Osteoid Osteomas         (CTOO Trial)

What is an osteoid osteoma?

Osteoid osteomas are painful bone tumors and make up about 10 percent of all benign bone tumors. They are most common in patients under the age of 25, particularly adolescents, with males affected three times more often than females.

Osteoid osteomas produce pain which is typically most severe at night and relieved by non-steroidal anti-inflammatory medications such as ibuprofen. When pain begins to significantly interfere with activities of daily living despite medication, or if severe symptoms persist, many patients are referred for a minimally invasive procedure to treat the tumor.

This MRI image demonstrates an osteoid osteoma within the femur (blue arrow) being treated with HIFU. In this patient, the central nidus appears bright on this imaging sequence. The HIFU machine focuses sound waves on the small tumor in order to generate heat and destroy the tumor.

Radiofrequency ablation guided by CT imaging (CTgRFA) is the most common procedure used to treat osteoid osteomas.

   

Osteoid osteomas trial overview

• Osteoid osteomas can become painful enough to interfere with regular activity.
• Many patients over the age of 10 can enroll in a clinical trial to treat osteoid osteomas with high-frequency focused ultrasound (HIFU).
