Zielsetzung Osteoid osteoma is a benign bone tumor characterized radiologically by an intracortical nidus with a variable amount of calcification, as well as cortical thickening, sclerosis, and bone marrow edema. The aim was to summarise epidemiological, radiological and clinical findings and to evaluate the treatment results of patients with osteoid osteomas handled in our institution.

Material und Methoden 117 patients with osteoid osteoma were studied retrospectively from January 2005 to September 2019. The study included 39 females and 76 males with the mean patient age 22.5 years patient (age range from 2 to 60 years). Radiographic images, including X-ray, CT, and MRI were analyzed for the presence of typical imaging findings. CT was performed in 97 patients, MRI in 106 patients.

Ergebnisse The lesions were most frequently located in the tibia (n=35; 30,4%), the femur (n=34; 29,6%), humerus (n=9; 7,8%), and the radius (n=5; 4,3%). The rest of the lesions (n=32, 27,4%) were located in scapula, radius and ulna, hands, spine, pelvis, patella, fibula, and feet. The average diameter was 8 mm. Lesions were located cortically in 83,6% of the cases. Aspirin test was done in 27 cases and was positive in 14 (55,6%). A total of 109 patients underwent treatment at our institution: 55 were treated surgically, and 54 with radiofrequency ablation (RFA). The primary clinical success rate in our study in RFA and surgically treated patients was 88,9%, and 92,7%, respectively. The secondary clinical success was in both groups 100%.

Schlußfolgerungen Osteoid osteoma is predominantly found in male patients, is frequently arising in the lower extremities, and is usually located cortically. RFA is when compared to surgical treatment, reliable, and efficient treatment option in osteoid osteomas.
