Osteoid osteoma of the thoracic spine: report of a case.

Osteoid osteoma occurring in the thoracic spine, manifest as purely referred pain, is extremely uncommon. In the case of a 24-year-old man, the treatment for painful osteoid osteoma of the spine was excision. Since excision of a thoracic spinal osteoid osteoma compromised stability, a posterior fusion was performed at the time of excision, and the results were excellent.
