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. aDepartment of Pediatric Orthopedic Surgery, Regina Margherita Children’s Hospital, Torino, Italy bDepartment of Pediatric Surgery, University Hospital Estaing, Clermont Ferrand, France Correspondence to Federico Canavese, MD, PhD, Department of Pediatric Surgery, University Hospital Estaing, 1, Place Lucie et Raymond Aubrac, 63003 Clermont Ferrand, France Tel: +33 4 737 50296; fax: +33 4 737 50291; e-mail: firstname.lastname@example.org Copyright © 2018 Wolters Kluwer Health, Inc.
