Estimation of Stature from Left Tibial Length in Young Adult Males: A Cross-sectional Study

Introduction: Estimation of stature by measurement of various bones is of immense value in the identification of an individual. Tibial length measurement is a reliable anthropometric parameter commonly used for estimating an individual’s stature, especially in forensic and archaeological contexts. It provides accurate results due to the strong correlation between tibial length and overall body height. Aim: To find the relationship between the stature and length of the left tibia of an individual and derive a linear regression equation to calculate the height from the length of the left tibia. Materials and Methods: The present analytical cross-sectional study was conducted in the Department of Anatomy, Pacific Medical College and Hospital, Udaipur, Rajasthan, India, from June 2023 to June 2024. Sample population was 200 males between the age group of 17 years to 24 years. Spreading calipers was used to measure left tibial length in the sitting position. The bony prominences used for this were medial malleolus of the tibia and medial epicondyle of left lower limb. The height was measured by stadiometer. Statistical analysis was done to determine the regression equation for stature estimation. The relationship between tibial length and height was established using a regression equation and then the p-value for the slope (regression coefficient) of that equation was calculated. Statistical Package for Social Sciences (SPSS) V 30 software was used for statistical analysis. Results: The mean height of male subjects was found to be 162.47 cm. Mean percutaneous length of left tibia (x) was found to be 35.99 cm for males. The correlation coefficient was 0.658 and the regression equation was Y = 71.361+2.575X (Tibial Length). Conclusion: The present study reveals that a positive and statistically significant correlation exists between the percutaneous tibial length and stature.
