Simple and Safe Excisional Technique of Osteoid Osteoma of the Proximal Femur and Distal Tibia Using Hollow Reamer: A Case Report

Osteoid osteoma is a small benign bone tumour, most frequently seen in young patients, usu-ally solitary, and common in male patients (about 80% < age of 30 years). We present two cases of osteoid osteoma. 1st case of a 14-year-old male patient with osteoid osteoma distal 2/3rd of the left femur. 2nd case of 75 years old male patient with osteoid osteoma distal 1/3rd right tibia. In both cases, radiography and computed tomography revealed osteoid os-teoma that was successfully treated with simple and safe percutaneous computed tomogra-phy and radiography-guided excision using a hollow reamer technique.
