Stature estimation from long bones uses regression equations. Which bone provides the MOST accurate stature estimate, and in what order do bones rank from most to least accurate?
- A Tibia > Femur > Humerus > Radius
- B Femur > Tibia > Humerus > Radius ✓
- C Humerus > Femur > Tibia > Radius
- D Radius > Tibia > Femur > Humerus
Correct answer: B. Femur > Tibia > Humerus > Radius
Explanation
The femur has the highest correlation with total stature because it is the longest bone in the body and its length is strongly linearly related to standing height. The regression formulas (Pearson, Trotter and Gleser) rank femur first, followed by tibia, then humerus, then radius, in decreasing accuracy. This order reflects the proportional contribution of each bone to total body height. The tibia is second because it directly reflects lower limb length.
