The frequency of types of calcaneus in according by the modified classification of talar articular facets
Classification calcaneus by form of talar articular surfaces, used for identification purposes, has implications for anthropological, comparative anatomical, forensic medicine and applied clinical research. The purpose of the study - to determine the frequency types of calcanea by form of articular facets in the modified and supplemented classification, in which for the differentiation of 1 type of calcanea by authors were introduced quantitative criteria. 1a subtype detected in 14 %, 1b in 24.6 %, 1c in 7%, 2a subtype in 7 %, 2b in 15.8 %, 2c in 22.8%, the third type in 7% and 4th type in 1.8 % of cases. In the analysis of data proven absence of bilateral and presence of sex differences by the modified classification criteria statistically. Introduction of quantitative criteria for subtyping allows, according to the authors, unify of research and to produce a comparison of results obtained using different classifications. Proposed quantitative criteria can be used to differentiate the degree of fusion of talar articular surfaces of the calcaneus.
