Preliminary report of total ankle arthroplasty for osteonecrosis of the talus.

Osteonecrosis of the talus secondary to adrenal corticosteroids is rare. The pathophysiology of the disorder is controversial. This is a report of bilateral talar necrosis secondary to steroid medications in a 23-year-old male. Conservative methods of management of the condition are not altogether satisfactory. Bilateral ankle replacement in this case resulted in alleviation of pain and improvement of function.
