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.
