Abstract

Os subtibiale is a rare accessory ossicle of the ankle, considered not of clinical significance. But its presence in trauma patients may cause misdiagnosis as malleolar fracture and over-treatment. Because the ossicle is attached to the deltoid ligament, ankle trauma that cause medial compartment injury may detach os subtibiale from medial malleolus. In these situations, MR imaging may help to diagnose the deltoid injury, demonstrate the features of the ossicle, and guide treatment.
