Management of complications following radiofrequency ablation of a pedicle osteoid osteoma.

Radiofrequency ablation (RFA) has become an accepted first-line treatment for osteoid osteomas. Ablation of spinal osteoid osteomas has presented a particular challenge because of their proximity to delicate neural structures. Although many case series have reported multiple successfully treated spinal osteoid osteomas, there are no reports of thermal injury or insufficiency fracture associated with RFA of spinal osteoid osteomas. We report the management of complications that result from treating a spinal osteoid osteoma within a pedicle.
