Aim. To review ten-years experience in diagnostics and operative treatment of osteoid osteoma. Methods. A total of 15 patients were retrospectively analyzed in this study. Clinical diagnosis was based on medical check-up, aspirin test, and conventional laboratory and radiographic examinations. CAT scan radionuclide bone scan, and magnetic resonance were performed in certain cases. All the patients were operatively treated by local resection of the tumor-infested bone. The resected part of the bone was intraoperatively checked by X-ray. The aim of this examination was to verify nidus in the resected bone. Afterwards, the resected bone with nidus was histologically analyzed. Results. Osteoid osteoma was histologically verified in 86.6% of cases. Other forms of bone tumors were verified in 13.3%. In the early postoperative period patients were without previous discomforts. Future treatment consisted of regular medical check-up of all the patients. In order to verify the final results, in February 2002 another medical check-up was performed for 11 patients, upon their consent. All of the patients with verified osteoid osteoma were without discomforts. Medical findings were regular in each case. Conventional radiography showed a solid bone remodelling in place of resected bone. Conclusion. Osteoid osteoma is a benign bone tumor with typical clinical and radiographic findings. Operative treatment represents a method of choice and demands accurate preoperative localization of the lesion, with the help of computer-assisted tomography.
