Os Trigonum Syndrome is a condition causing pain at the back of the ankle that originates from an extra bone that sometimes develops from the posterior talus.
The Os Trigonum is an accessory ossicle or extra bone in the posterior to the ankle joint, present in 5-15% of the population. Os Trigonum Syndrome refers to pain in the posterior talus and reduced plantarflexion ( ability to point your toes) caused by the “nutcracker-phenomenon”. The “nutcracker phenomenon” is where the os trigonum is crushed between the talus and calcaneus bones. This leads to inflammation and pain of the involved structures.
The simple presence of an ossicle does not cause the syndrome. Os Trigonum Syndrome is usually caused by an injury to the area, such as an ankle sprain. The condition can also be caused by repeated downward pointing of the toes, in activities such as ballet or soccer.
In the case of a fracture, your physiotherapist may recommend a CAM boot.
