Sex assessment using the proximal tibia

Abstract
The proximal end of the human tibia is sexually dimorphic. Tibial condyles from 100 individuals in the Hamann‐Todd Collection were measured. Regression equations retrodicted known sex with 86–95% accuracy. A test sample of 20 individuals also from the Hamann‐Todd Collection was classified with 85–100% accuracy. A sample of 20 prehistoric individuals provisionally sexed by using crania and innominate bones was classified with 85–100% agreement. Thus, the proximal tibia may be useful in determining the sex of a skeleton.
