Bone formation is not impaired by hibernation (disuse) in black bears Ursus americanus
S.W. Donahue, M.R. Vaughan, L.M. Demers, H.J. Donahue
2003, Journal of Experimental Biology (206) 4233-4239
Disuse by bed rest, limb immobilization or space flight causes rapid bone loss by arresting bone formation and accelerating bone resorption. This net bone loss increases the risk of fracture upon remobilization. Bone loss also occurs in hibernating ground squirrels, golden hamsters, and little brown bats by arresting bone formation...
