Info
No bone fracture or dislocation is seen. A small well-corticated bone fragment is noted adjacent to the medial malleolus which is likely an os subtibiale.
Case Discussion
Os subtibiale is an uncommon accessory ossicle, discovered as an incidental finding and should not be confused with a fracture in the trauma setting.
