Forensic Anthropology: Stature Estimation from Long Bones

Stature estimation from skeletal remains is one of the four pillars of the biological profile in forensic anthropology, alongside sex, age, and ancestry. This drill covers the full protocol: osteometric board measurements of maximum length on the femur, tibia, fibula, humerus, radius, and ulna; the regression-based methods of Trotter and Gleser (1952, 1958, 1977 corrections) for American White and Black males and females; the older Pearson (1899) formula developed on French and Belgian skeletal collections; and the India-specific formulae by Pan (1924) for Hindu males, Saxena (1984) for north Indian bones published in the Indian Journal of Medical Research, and Sahni and colleagues whose work established population-calibrated equations for north and northwest Indian adults. Questions probe the osteometric landmark protocol on the femur bicondylar vs maximum length distinction, which bones produce the tightest standard error of estimate, what population limits Trotter-Gleser, how Pan differs from Saxena in sample base, and how the Steele method handles fragmentary diaphyseal segments when neither epiphysis is intact.

Aimed at UGC-NET Forensic Science Paper II aspirants targeting Unit X (Physical Anthropology and Forensic Anthropology), NFSU MSc students, AIIMS Delhi forensic medicine postgraduates, and CFSL and state FSL staff working skeletal identification casework. The Indian Journal of Forensic Medicine and Toxicology (IJFMT), Journal of the Indian Academy of Forensic Medicine (JIAFM), and NICFS Delhi training materials form the primary Indian-context reference base alongside Bass (Human Osteology, 5th ed) and Krogman and Iscan (The Human Skeleton in Forensic Medicine, 2nd ed).

Topics covered:

• Osteometric board protocol: maximum length, physiological length, landmark definitions
• Bone selection: relative accuracy of femur, tibia, humerus, radius, ulna
• Trotter-Gleser 1952 and 1958 formulae: population groups, correction factors, 1977 revision
• Pearson 1899 method: French-Belgian sample base and population limitations
• Pan 1924 formulae for Indian Hindu males
• Saxena 1984 Indian north Indian population equations and IJMR publication
• Sahni Indian formulae and comparison with Saxena
• Steele method for fragmentary long-bone diaphyses
• Combined multi-bone regression and allometric approaches
