Seven patients vvith osteoid osteoma and four patients vvith osteoblastoma of the spine were followed after operative excision of the tumor. The patient group consisted of 11 patients, 6 females and 5 males, vvith mean age 14.4 years (4 to 20). The average follow-up period vvas 25.4 months with a range from 6 months to 4.5 years.

The lumbar spine vvas involved in eight cases, thoracic spine in two and cervical spine in one. İn ali cases, the lesion vvas located in the posterior vertebrai elements vvith a common complaint of back pain on presenta-tion. Aspirin or naproxen afforded good symptomatic relief in four patients. Tvvo patients presented vvith painful scoliosis.

Full recovery follovved complete excision in ali cases. One case required posterolateral fusion and instru-mentation due to instability created by excision of the lesion. Follovving surgery, pain complaint vvas complete-ly relieved and by one case the spinal curvature had partially regressed.

An underlying osteoid osteoma or osteoblastoma of the spine must be strongly suspected in ali young patients presenting vvith back pain and painful scoliosis. Preoperative evaluation should include a bone scan and computed tomography to lozalize the tumor accurately. If early diagnosis can be achieved, the scoliosis is re-versible after excision of the tumor. When the spine becomes unstable due to the extet of the excision, sta-bilization may be required.
