Surgical Results of Osteoid Osteoma Treatment

Abstract

Aim: Osteoid osteoma (OO) is one of the most common benign tumors of the bone. Treatment of choice is usually the resection of the nidus. In this study, we assessed the surgical treatment results in patients with OO who were experiencing severe pain. Methods: We included 39 patients with OO who were treated by surgical method in our clinic. Clinical features, radiological findings, surgical method and the success of the treatment were assessed. Results: Twenty-four patients were male and 15 patients were female. The mean age of the subjects was 19.6 years. The most common sites were the femur (17) and tibia (11). Nidus was detected by plain radiography in 18 of 39 patients, by computed tomography in 28 of 32 patients, by magnetic resonance imaging in 11 of 24 patients, by bone scintigraphy in 10 of 18 patients. Relapse was seen in four of 39 patients and for three of them, surgical curettage was performed. Conclusion: The character of the pain and thin-section computed tomography must be evaluated together the make the diagnosis. The nidus must be removed completely in the treatment of osteoid osteoma. The success of the treatment is defined both by the relief of the pain and no nidus seen on radiological examinations.
