A forensic anthropologist is estimating stature from a fragmentary femur where the total length cannot be measured directly. Which measurement of the femur is MOST commonly used for stature estimation when only fragments are available?

• A Anteroposterior diameter of the shaft at midshaft
• B Maximum vertical diameter of the head
• C Pilasteric (linea aspera) length ✓
• D Physiological length from head to medial condyle

Explanation

When the femur is fragmented, the pilasteric length (linea aspera length) is used in regression equations for stature estimation. The anteroposterior diameter and head diameter are used for sex determination, not stature. Physiological length requires an intact bone, which contradicts the premise of fragmentation. Fully anatomical length is preferred when available, but fragmentary methods are standard in forensic practice.
