Excision of osteoid osteoma with intramedullary reaming: a new method.

Osteoid osteoma is a small benign bone tumor usually affects adolescents and young adults. Although this tumor mainly affects the shafts of long bones there have been several reports of subperiosteal and intramedullary involvement .Complete surgical excision is the classic treatment of choice for patients with osteoid osteoma. Despite the small size of the tumor, the operative procedure for its removal can be extensive .The surgeon may have to excise a significant piece of bone to be sure the lesion is removed. There is a risk of fracture if a large amount of bone is removed and therefore internal fixation, bone grafting, or both may be required. In recent years several techniques of minimally invasive treatment of osteoid osteoma have been proposed. We introduce intramedullary reaming as a minimally invasive procedure for the treatment of intramedullary osteoid osteoma in long bones.
