Appendicular osteoid osteoma: percutaneous excision under computed tomography guidance using goaxial drill technique

Eleven cases of osteoitd osteomas of tubular bones were resected percutaneously under CT guidance. Diagnosis was made on the basis of clinical and radiological findings. Histopathological confirmation was obtained in 10 cases. Successful treatment was achieved in all patients. Because of the focal bone resection, no bone grafting was needed. Hospital stay lasted from 1 to 3 days. After 2-13 months of follow up, all patients were asymptomatic. We recommend percutaneous excision under CT guidance as the procedure of choice in the treatment of the appendincular osteoid osteoma
