RESUMO
Introduction: There are three facets over superior surface of calcaneum which forms Sub talar or talocalcaneal joint: Anterior, middle, and posterior talar facet. Three types of calcaneum that have distinct talar facets Were defined as types A, B and C. Materials and methods A total of 250 calcaneum (130 right, 120 left), with unknown gender, were dried and evaluated. Results In our study type B calcaneum (68.8%) was defined as the most common type, and type A calcaneum (30.8%) was second. By using joint facet differences and bone measurement, we tried to define calcaneum bone. Discussion In many diseases of foot, such as the talocalcaneal arthritis and coalition, intra articular fractures and congenital dysmorphology, flatfoot, valgus deformities, the size and shape of the bones, the relationships of the talus and calcaneum with each other and other bones of the foot must be considered for the internal and external fixation and surgical procedures. Type B calcaneum was defined as the most common Type in Gujarat region and these results correlate with the ones which were performed on bones of American, Indian and African, Turkish race and it was uncorrelated with the results of the Researches performed in Europe.
