Osteoporosis Osteoporosis is defined as a hereditary condition marked by excessive calcification of bones causing spontaneous fractures and marble like appearance. Osteoporosis usually goes unnoticed until fractures in the spine of hip occurs. This disease is characterized by low bone mass and thinning of the bone tissue. It becomes fragile and is easily fractured.
Bone is living tissue.
It is dynamic. It breaks down and rebuilds itself. As we go, bone turnover changes. The rate of growth decreases while removal of old bone continues. A bone scan is done to measure the density of the spine and hip.
