title: Solitary osteochondroma of the sinus tarsi.
abstract: Tumors are a rare cause of ankle-region pain. Osteochondroma is one of the most common benign bone tumors, but is rarely localized to the foot bones. Here, we describe a case of a solitary osteochondroma of the sinus tarsi presenting in an 8-year-old boy with a history of recurrent ankle sprains and limited range-of-motion of the subtalar joint. Treatment was surgical excision of the tumor, and the patient is now symptom free. Clinical presentation, treatment, pathoanatomy, localization, and complication of this benign form of tumor are discussed and all previously reported cases are reviewed to provide a more comprehensive picture of osteochondroma of talus.
