Ruff–Scott–Liu 1991 Study
Definition
A study of radiographic proximal femoral dimensions in 80 living adults with reported current and age-18 weights. It examined how articular and shaft dimensions relate to adult weight change. Femoral head size did not track adult weight change like shaft structure; this is not a direct measurement of weight at death.
