WebA new paradigm has emerged that invokes osteocyte apoptosis as a critical event in the recruitment of osteoclasts to a specific site in response to skeletal unloading, fatigue damage, estrogen deficiency and perhaps in other states where bone must be removed. WebIt is clear that aging is associated with loss of bone mass, intracortical remodeling and increased bone fragility and accumulating evidence suggests that the age related degeneration of the osteocyte network and its lacunocanalicular system may play a role in this deterioration of bone quality.
