ARTHROSCOPIC REMOVAL OF AN OSTEOID OSTEOMA AT THE TALAR NECK

The case of-a 14-year-old girl with osteoid osteoma of the talar neck that localized subperiostaly with a 1-year history of persistent ankle pain is presented. The diagnosis was made on the basis of clinical ap pearance, radiography, technetium-99m diphosphonate scintigraphy, and magnetic resonance imaging findings. Subsequently, she underwent arthr oscopic excision of the lesion using a motorized burr and curette. Aft er the intervention, there was prompt relief of symptoms and no recurr ence during a follow-up period of 22 months. However, pathological stu dy of the arthroscopic shavings failed to confirm the preoperative dia gnosis. We concluded that the arthroscopic excision of an osteoid oste oma in an accessible location on the talar neck is an appropriate surg ical intervention, but it should be done by using nonmotorized instrum ents for better pathological examination of the lesion.
