Osteoid osteoma is a small, self-limiting osteogenic tumor. The success of the treatment depends on complete resection or destruction of the nidus. Open excision or en bloc excision was the classical treatment of osteoid osteoma before the development of minimally invasive percutaneous methods. Computed tomography guidance is required in the operating room in most of the percutaneous procedures. This enables accurate localization of the tumor and tumor excision can be performed with less bone tissue resection. We performed an alternative treatment that enables surgeons working in clinics where this equipment does not exist, to perform easy resection of the tumor through a mini incision. Mini incisional surgery seems to be an efficient and reliable treatment for osteoid osteoma.
