Clinical findings and results of surgical resection of thoracolumbar osteoid osteoma.
METHODS
Descriptive, cases series study.


OBJECTIVE
To evaluate clinical findings and results of treatment of patients with spinal osteoid osteoma who underwent surgery.


BACKGROUND
Osteoid osteoma is a benign tumor with spinal involvement rate of about 10%. It is manifested during adolescence with symptoms such as painful scoliosis. To treat the problem, operation on the patients and excising the nidus are suggested.


METHODS
This descriptive study was conducted on 11 patients with spinal osteoid osteoma at our orthopedic educational center. All patients were treated through open surgery and nidus curettage. All samples were pathologically confirmed. Imaging methods (spiral computed tomography-scan) was used in preoperative planning. Scoliosis and other clinical findings were studied.


RESULTS
The study was conducted on 11 patients comprising 6 females (54.5%) and 5 males (45.5%) with the mean age of 14.6 years. Mean deviation of scoliosis resulting from spinal osteoid osteoma was 22.8 degrees. There was more scoliosis in the involvement of the lumbar vertebra. In comparison with adults, scoliosis was more severe in youths. There was one case of vertebra body involvement with manifestation of painful scoliosis. Due to lack of careful preoperative examination, the surgery was repeated for this case. No sign of recurrence was observed in patients who underwent open surgery and all scoliosis in the follow-up had improved.


CONCLUSIONS
Based on our findings, surgical excision of spinal ostoeid osteoma was successful and complete recovery was achieved in spinal deformity in the course of follow-up. Scoliosis is often seen during adolescence and lumbar involvement is more severe.
