Local variation in age‐related cortical expansion within and between cross‐sections of distal human long bones

open access: yesThe Anatomical Record, EarlyView.
Abstract Cortical bone expansion is an age‐related process where, through endosteal resorption and periosteal apposition, cross‐sectional diameter increases while cortical thickness decreases in long bone diaphyses. Local variation has been observed in this process between cross‐sectional locations, but few studies have examined directional variation ...
