Radiofrequency ablation of a spinal osteoid osteoma: low heat-load technique.

摘要

The present report describes successful radiofrequency ablation of a small osteoid osteoma in the second lumbar (L2) pedicle of a 10-year-old boy who had been experiencing several months of back pain. The lesion had no cortical bone separation from the spinal canal contents and was positioned immediately adjacent to a synovial facet joint. Treatment involved a low heat-load technique to avoid damage to nearby sensitive structures. The adjacent epidural space was monitored for temperature increase.
