Presencia de huesos accesorios del tarso. Variantes anatómicas normales con potencialidad patológica
Abstract
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 motivate the study of their incidence. Our
objective is to determine the presence of different tarsal accessory
bones in a population sample. The result 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,
pre-existing ankle and foot x-rays in the institutional database, is
exposed. 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 presented 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.
