Variations in the Presence and Prominence of the Features in the Long Bones of Limbs (original) (raw)

2014, International Journal of Current Research and Review

The present study was undertaken, to report the subjectively observed variations in the presence and / or prominence of features in the long bones of limbs. Material and Method: The observed features multiplied with the total number of bones were: humerus 576(16x36); radius 240(8x30); ulna 270(9x30); femur 1008(16x63); tibia 380(10x38), fibula 152(4x38). The features were graded for their presence or prominence and analyzed for their combined/ individual total; total between and within the right and left sides. Results: The combined total of the presence and prominence of the features were greater for the right femur (576/1008, 57.1%). The individual total showed that the presence of features was greater in tibia (259/380, 68.2%) and prominence of features in ulna (164/270, 60.8%). Between sides, the prominence of the features was greater for right femur (355/603, 59%). Within the sides, the prominence of the features was high for ulna (82/126, 65%). X 2 value indicated that the prominence of the features for femur could be of value in side determination. The observations on the prominence of individual features in long bones of the limbs showed a high percentage value for the nutrient foramen in femur (56/63, 88.9%). Conclusion: From the present study, it is seen, that features could have become prominent due to genetic and/or environmental factors such as nutrition and biomechanics during the process of the formation of the features.
