A 50‐year perspective on the use and potential of artiodactyl calcanei in bone adaptation studies

open access: yesBiological Reviews, Volume 101, Issue 1, Page 437-485, February 2026.
ABSTRACT Sheep and deer calcanei are important models for studying cortical (compact) and trabecular (cancellous) bone adaptation because they are amenable to direct strain measurement (due to lack of surrounding muscles), experience relatively simple/unidirectional bending, exhibit osteon remodelling, and have the most pronounced regional variations ...
