NOLLA DELEON, Matías Sebastián; MACHAIN, Sebastián  and  RIVERO, Marcelo. Presence of accessory bones of the tarsus. Normal anatomical variants with pathological potential. Anfamed [online]. 2021, vol.8, n.2, e401.  Epub Dec 01, 2021. ISSN 2301-1254.

The group of pathologies under the name of foot and ankle pain syndromes encompass different tendinopathies associated among various clinical factors with the presence of accessory tarsal bones. The correct identification and radiological differentiation of these anatomical variants, by virtue of their ability to influence the normal dynamics of the tarsus, motivated the study of their incidence. Our objective is to determine the presence of different tarsal accessory bones in a population sample. Here we present the results of a retrospective observational study in 240 patients between 15 and 85 years of age, treated in a private health center in the city of Las Piedras, Canelones, with pre-existing ankle and foot x-rays in the institutional database. The presence of tarsal accessory bones was determined in 23 patients (9.58%), identifying findings of Os Trigonum (1.66%), Stieda Process (3.33%), Os Peroneum (2.93%) and Os Navicular (1, 66%). The corresponding frequency analysis and contingency study between the variants found, age and sex of the patient are exposed in tables. The result of the research seeks to contribute to the knowledge of normal anatomical variants correlative to under diagnosed pathological processes, from the role of radiological anatomy.
