title: Symptomatic Os Subtibiale Associated with Chronic Pain Around the Medial Malleolus in a Young Athlete.
abstract: An os subtibiale is a rare accessory bone located below or behind the medial malleolus. Herein we present a rare case of a painful os subtibiale in a young triathlete who presented with pain, redness and swelling below his left medial malleolus. Plain radiographs and three-dimensional computed tomography revealed a well-defined oval bone distal to the left medial malleolus. After conservative treatment failed, the ossicle was excised in an open surgery with complete resolution of symptoms. This case report emphasizes the need for clinical awareness of different anatomical variations of the bones of the foot.
