Microfractures in vertebrae getting older is as good as monitoring bone density if microfracturesi n vertebrae, they will change mm once we get to 60, your average height goes down by 0. 7 mm per yr. Main thing about bone is it is a biologically structured engineering thing, trabeculai in bone and cortices out there and they line up according to stresses imposed on them. One way you can make bones stronger is by doing exercise, exercise such as weight bearing, the right kind of weight bearing exercise, jogging exercise, walking, jumping, climinging stairs, vibrating platform, they work. Scanner for bone density readings and standardized to t score as we go through life we have a bell curve, lowest 1% classified as osteoporosis. If t score we get bell curve, by 60%, the bell curve is shifted down and as 80 yrs , if over. 80, it is normal and not unusual for osteoporosis, bone density relates to aging.
