Os trigonum is an accessory, or extra bone, behind the ankle. Many people with this extra bone do not develop symptoms. However, if the os trigonum causes pain, doctors refer to it as os trigonum An os trigonum is a small extra (accessory) piece of bone in the back of the ankle. While up to 15% of people have this extra bone, it usually does not cause any symptoms. It may be present only on one side but can be found in both feet. An os trigonum does not move as it attached by thick tissue to the talus bone just behind the ankle joint. The os trigonum exists as the result of a persistent, separate lateral ossification center on the posterior aspect of the talus that normally rapidly fuses with the medial and lateral tubercles during preadolescence. 32 Acquired os trigonum syndrome is caused by an injury that prevents fusion and can subsequently become symptomatic when it The os trigonum, hypertrophic posterior talar process, or a nonunion of a fracture of the posterior talar process is identified (Fig. 13.8a). The os trigonum can be lifted from the subtalar joint by a small-sized periosteal elevator. The periosteal elevator can help identify the fibrotic zone between the os trigonum and talus from above. El síndrome del hueso trígono es desencadenado habitualmente por una lesión. Tal como un esguince de tobillo. El síndrome es causado frecuentemente también por apuntar repetidamente los dedos de los pies hacia abajo, lo que es común entre bailarinas de ballet, jugadores de fútbol y otros atletas. Para la persona que tiene un hueso The os trigonum is an accessory (extra) bone that sometimes develops behind the talus (ankle bone) during adolescence. Not many people have this extra bone, and many of those who do are not aware of it. Os Trigonum Syndrome refers to posterior ankle pain and reduced plantarflexion caused by "the nutcracker-phenomenon".
