People in different age groups show different hip-joint morphology [PDF]

open access: yes, 1993
It has been suggested that the distribution of the subchondral bone density may be regarded as the expression of the long-term effective stress in a joint, and previous results indicate the regularity of the distribution of subchondral bone density as a ...
