Study of Variations in Pattern of Calcaneal Articular Facets in Human Tali in the Population of Rajasthan (India).
Journal Title: People's Journal of Scientific Research. - Year 2013, Vol 6, Issue 2
Abstract
Talus (astragalus) is the second largest tarsal bone. It has no muscular or tendinous attachment. It takes part in the formation of various articulations in the form of talocrural , talocalcaneonavicular or subtalar joints. The prior knowledge of the anatomical set of talus and its various articulations holds significance in operating procedures. Knowing anatomy of talus not only helps in delineating underlying pathology but also helps in treatment. Three hundred dry adult tali (150-right and 150-left) were studied. Each talus was examined for the presence of various patterns of articular facets. They were classified into five groups. Type I was found in 39% cases. Type II in 43.7% cases, Type III in 6% cases, Type IV in 5.3% cases and Type V was in 6% cases; type V has two subtypes. Subtype ‘A’ was found in 5% cases & subtype ‘B’ was found in 1% cases. In the present study, highest incidence of type II tali was 43.7 % and type IV had lowest incidence of 5.3%. These variations and their incidences can be used as an anthropological marker for racial and regional differences in unidentified bones. Further, studies on various other population is indicated using larger sample size to make comparative studies more meaningful.
