Abstract

We report a case of a subperiosteal osteoid osteoma on the talar neck that was removed arthroscopically. Intralesional excision, en bloc resection, and percutaneous ablation techniques have all been used for the treatment of osteoid osteoma. For intra-articular osteoid osteomas, arthroscopy-assisted removal of the tumor has been described in a few case reports. Obtaining a nidus fragment for pathologic evaluation is important during arthroscopic removal of intra-articular osteoid osteomas. Sometimes it is not possible to obtain a specimen for pathologic examination. In the present case, the osteoid osteoma on the talar neck was easily located, the nidus was completely removed, and the tumor was extirpated. (J Am Podiatr Med Assoc 97(3): 238–243, 2007)
