Abstract: Os trigonum is located at the posterolateral of talus and rarely it can be bipartite.Os trigonum is connected to the talar process by fibrocartilage structure.It is seen as the process of the lateral tubercle of the posterior talar process when fusion happens, also known as "Stieda process".[1][2][3][4][5] Fractures of this small accessory bone are rarely reported in the literature.Only eight cases reported in the literature were identified.[1,[6][7][8][9][10][11] Most of the cases in the literature occurred with falling from a stair, falling from a height and during sports.Injury that causes the os trigonum fracture usually happens by the overloading of the ankle in acute hyperplantar flexion.[9] Dancers and athletes who participate in kicking sports are particularly susceptible to these injuries because their feet are in a forced plantar flexed position.[12] X-ray, computed tomography (CT) and magnetic resonance imaging (MRI) scans can be used in the diagnosis of os trigonum fractures and accompanying injuries.[3,6,7] Generally, os trigonum fractures are treated with short leg cast for six weeks of duration.[1] These injuries are often confused with Achilles tendon Os trigonum fractures are seen rarely.Our patient was a 16-year-old male patient who applied to our emergency service with right ankle pain due to acute hyperplantar flexion while playing football.There was a swelling on the right ankle and he had difficulty in walking.Os trigonum fracture was detected at lateral X-ray of the right ankle.No additional injury was detected with computed tomography and magnetic resonance imaging (MRI).Patient was treated conservatively.A short leg cast was applied.Cast was removed after six weeks and range of motion exercises were started.Union of fracture was seen on X-ray at six weeks from injury.Conservative treatment is thought to be a good option in these fractures.Computed tomography and MRI are important in the differential diagnosis and evaluation of additional injuries in this type of fracture.
