An accessory bone, Os trigonum is placed at the posterior of talus. Os trigonum occurs as ossification center between 7-13 years at the posterior of talus and combines with talus within a year. However, this combination does not occur in 7 % of population that results in Os trigonum syndrome. Os trigonum syndrome is a clinic disorders that can cause posterior foot pain. This bone causes back foot pain as a result of compression between talus and calcaneus. These symptoms are seen as a result of repetitive strain or traumas that are frequently seen in ballerinas and soccer players with the force of ankle to plantar flexion. People with Os trigonum are generally stated to be asymptomatic, however due to additional risk factors that cause posterior foot pain such as overuse or occupational one can call this syndrome to be symptomatic. In this study two different cases with symptomatic Os trigonum are reported one due to wearing of high heel shoes and other due to occupational overuse (farming). In this report we present two cases of an 18 years and a 65 years old who have back foot pain and diagnosed with os trigonum syndrome with the review of current literature.
