Os trigonum was first described by Rosenmuller in 1804. Os trigonum is an accessory bone located on the posterolateral side of talus. It usually develops as a separate ossification center next to talus at the age of 8-13 and it is expected to fuse within 12 months. If fusion does not occur, it develops as a separate bone and it is named os trigonum. Os trigonum causes pain in the back of the foot by compressing between talus and calcaneus as a result of excessive plantar flexion of the foot, and thus showing symptoms of an asymptomatic condition is called os trigonum syndrome. Os trigonum was detected with the help of Direct Radiography (DR) and Magnetic Resonance Imaging (MRI) methods in a 15-year-old male patient who was admitted to the emergency trauma unit of our hospital with pain and swelling in his right foot due to a sprain in his ankle while playing football.

Os trigonum ilk kez 1804 yılında Rosenmuller tarafından tanımlanmıştır. Os trigonum talus’un posterolateral tarafında yer alan aksesuar bir kemiktir. Genellikle 8-13 yaşlarında talus’un yanında ayrı bir ossifikasyon merkezi olarak gelişim gösterir ve 12 ay içinde kaynaşması beklenir. Kaynaşma gerçekleşmez ise ayrı bir kemik olarak gelişir ve os trigonum adını alır. Os trigonum ayağın aşırı plantar fleksiyonu sonucu talus ve calcaneus arasında sıkışarak ayak arka kısmında ağrıya neden olur ve böylece asemptomatik olan durumun semptom göstermesine os trigonum sendromu denilmektedir. Hastanemizin acil travma birimine futbol oynarken ayak bileğinde burkulma sonucu sağ ayağında ağrı ve şişlik şikayeti ile başvuran 15 yaşında erkek hastada Direkt Grafi (DG) ve Manyetik Rezonans Görüntüleme (MRG) yöntemleri yardımı ile os trigonum tespit edilmiştir.
