Q

Osteoporosis

A

Diminution of both the mineral and matrix components of bone such that the remaining bone is normal in composition but reduced in total bone mass. The secondary cause of osteoporosis is immobilization such as casting. Primary osteoporosis is an age-related disorder characterized by decreased bone mass and by increased susceptibility to fractures in the absence of other recognizable causes of bone loss.
