For estimating stature from skeletal remains, Trotter and Gleser regression equations use measurements of long bones. The bone that provides the MOST accurate stature estimation from these equations is:
- A Femur ✓
- B Radius
- C Humerus
- D Tibia
Correct answer: A. Femur
Explanation
Among the long bones used in Trotter and Gleser's regression equations, the femur provides the highest correlation coefficient with stature (r ≈ 0.93–0.95), followed by tibia (r ≈ 0.92), fibula, humerus, radius, and ulna. The femur is the longest and most robust bone and carries the highest proportion of total height. When the femur is unavailable, tibia provides the next best estimate. Using multiple bones in combination improves accuracy. Population-specific equations (Indian, African, East Asian) should be applied when available.
