ConclusionsConclusions
Predictable age related changes in the Predictable age related changes in the trabecular structure of the human pubic trabecular structure of the human pubic symphysissymphysis
Changes in trabecular structure can be Changes in trabecular structure can be particularly useful for estimating the age of particularly useful for estimating the age of older adultsolder adults
