The use of radioguided surgery in the resection of osteoid osteoma

Abstract

ObjectiveOsteoid osteoma is the third most common benign bone tumor and complete surgical resection is definitive treatment. There are a limited number of publications on the use of radioguided surgery in this type of lesion.To assess the utility of radioguided surgery in our environment as a method of surgical treatment of this tumor. Material and methodsWe retrospectively evaluated 12 patients (2 women and 10 men, age range 9–44 years) with clinical and radiological suspicion of osteoid osteoma. Bone scintigraphy showed foci of pathology uptake compatible with suspected lesion in the femur (4 cases), tibia (3), vertebral column (3), humerus (1) and talus (1). Subsequently patients underwent surgical treatment by radioguided surgery after injection of a dose of 99mTc-hydroxy diphosphonate. The nidus was removed using gamma probe and mini gamma camera, considering the technique to be completed when its counts decreased to the levels of the surrounding bone counts. ResultsLesions were located in all patients (12 of 12), and were confirmed histologically in eight of them, including an osteoblastoma. The cure rate was 100%, based on the disappearance of pain after a minimum follow-up of 6 months. ConclusionUse of radioguided surgery in the surgical treatment of osteoid osteoma showed satisfactory results, with 100% efficiency in both lesion location and outcome of treatment and without major postoperative complications.
