Correlation between length of tibia and dimensions of distal articular surfaces: a morphometric study

Background: Estimation of stature can be done from long bones especially tibia and femur as they have a correlation with height. Tibia is most commonly used as it resists erosion and keeps its anatomical shape even after burial. However intact bones are rarely available. Most often the exhumed remains are in fragmentary condition leading to lack of adequate sample for the study. A way of increasing utility of such samples would be the establishment of techniques which would permit estimation of stature from long bone fragments. The current study provides a correlation between length of tibia and its distal dimensions which can be used in anthropology for measuring the stature of an individual. Methods: A total of 50 tibiae were obtained from the bone bank of the Department of Anatomy, Government Medical College, Srinagar. Measurements were taken from the bone using vernier calipers. Morphometric data obtained was analyzed, measurements expressed in mean and standard deviation and Pearson’s correlation test was carried out. This observational study was conducted within a period of 2 months, from April-June 2022. Results: Width of talar facet with a Pearson’s correlation of 0.62 and width of fibular notch with a correlation of 0.3 showed positive statistical significance (p<0.05). On the other hand, breadth of medial malleolus with a correlation of 0.18 and height of fibular notch with a correlation of -0.02 (p>0.05) was statistically insignificant. Conclusions: The study showed a positive correlation (p<0.05) between length of tibia with the width of talar facet and fibular notch

Not Availablet In this study, the genetic relatedness of 82 walnut genotypes adapted to the North Western Himalayan region of Jammu and Kashmir, India was analyzed by combination of 13 SSR and 20 RAPD primers. A high level of genetic diversity was observed within populations with the number of alleles per locus ranging from one to five in case of SSR primers and two to six in case of RAPD primers, the proportion of polymorphic loci was 100 %, and similarity ranged from 12 % to 79 % with an average of 49 %. Dendrogram showed that all the accessions formed four main clusters with various degree of subclustering within the clusters. These results have implications for walnut breeding and conservation.Not Availabl
