Osteoid osteoma is a small benign tumor, with a "nidus" that rarely exceeds 15 mm in diameter. It is relatively common in males, especially teenagers and young adults. It involves mainly the appendicular skeleton, the femur in particular, and rarely the axial skeleton. It requires treatment because it causes intense pain. In recent years alternative, less invasive, treatments have been proposed, such as drilling combined with ethanol injections, and thermal ablation with laser or radiofrequency. This study assesses 117 patients affected by osteoid osteoma, treated by radiofrequency thermal ablation between June 2001 and November 2003. We describe the patient recruitment procedure, CT-guided technique, the percutaneous approach, thermal ablation, and the instruments used. Data were analyzed thoroughly, and modifications that have improved the effects of treatment have been high-lighted. The results achieved since the method was perfected have been extremely encouraging, confirming that the technique is very effective if performed correctly. For that reason radiofrequency thermal ablation has become the treatment of choice for non-spinal osteoid osteoma at Rizzoli Orthopaedic Institute.

Abstract

Osteoid osteoma is a small benign tumor, with a "nidus" that rarely exceeds 15 mm in diameter. It is relatively common in males, especially teenagers and young adults. It involves mainly the appendicular skeleton, the femur in particular, and rarely the axial skeleton. It requires treatment because it causes intense pain. In recent years alternative, less invasive, treatments have been proposed, such as drilling combined with ethanol injections, and thermal ablation with laser or radiofrequency. This study assesses 117 patients affected by osteoid osteoma, treated by radiofrequency thermal ablation between June 2001 and November 2003. We describe the patient recruitment procedure, CT-guided technique, the percutaneous approach, thermal ablation, and the instruments used. Data were analyzed thoroughly, and modifications that have improved the effects of treatment have been high-lighted. The results achieved since the method was perfected have been extremely encouraging, confirming that the technique is very effective if performed correctly. For that reason radiofrequency thermal ablation has become the treatment of choice for non-spinal osteoid osteoma at Rizzoli Orthopaedic Institute.
