Clinical Findings and Results of Surgical Resection of Thoracolumbar Osteoid Osteoma

STUDY DESIGN: Descriptive, cases series study. PURPOSE: To evaluate clinical findings and results of treatment of patients with spinal osteoid osteoma who underwent surgery. OVERVIEW OF LITERATURE: 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.

Osteoid osteoma of a scapula: a case report in a 34 years old woman

Osteoid osteoma is a benign bone tumor and accounts for 10% of benign tumors. Almost any bones can be involved but half of cases involving femur or tibia. Osteoid osteoma is a rare tumor of the scapula with only 18 reported cases in the literature. We presented a case of osteoid osteoma of the scapula in right shoulder in angle of coracoid and geloneid in a 34- year old woman. She had right radicular shoulder pain increased at night for 4 years. An important point about this case is that, patient was treated in long-term with miss diagnosis of cervicospinal discopathy. The key of diagnosis in this patient was paying attention to the nature of night increasing pain and performing bone scan. After the operative curettage of the tumor, the pain dramatically stopped and a few weeks of physical therapy led to full range of motion in her shoulder
