Introduction

About sixty years before, Fuller Albright characterised osteoporosis as a infection where there is "too little bone in the bone, but what bone there is, is normal". By this he intended that, although some bone mass is lost, the chemical composition of the remaining bone is normal. At that time, we knew little about osteoporosis and had no entails to heal or avert it, other than mending the fractures, the supreme clinical sequelae of the disease. Bone mass (most often conveyed as areal bone inorganic density) is only one of the constituents of bone strength. Others include bone value, structure and turnover. However, it is well established that bone density and bone power are highly, whereas imperfectly, correlated. Since it is hard to assess bone value or structure accurately in vivo, especially in humans, we depend on the estimation of bone mass in considering general bone strength and fragility.

In the past couple of decades, our comprehending of bone metabolism and pathogenesis of fractures has developed tremendously because of the advanced expertise in assessing bone inorganic density (BMD) and in recognising and quantitating the markers of bone turnover. In supplement, we now realise the significance of maximizing peak bone mass (PBM) throughout the first couple of decades of life. The words of endocrinologist, Charles Dent, granted 30 years before in his key-note address to the International Symposium on Clinical Aspects of Metabolic Bone Disease, that "senile osteoporosis is a paediatric disease," are now completely justified.

It is worth noting that, like in numerous other situations, there is a continuum in bone health for any granted age assembly or segment of community, which is genetically very resolute and possibly environmentally modified. Because bone mass in community conforms to a continuum other than to a pointed bimodal distribution, it is often hard to differentiate between healthy or osteoporotic bone, founded easily on a BMD measurement. The value of a bone and other risk components have to be taken into consideration. Table 1 presents the present World Health Organization (WHO) criteria for the diagnosis of osteoporosis

 

BONE CHANGES THROUGHOUT LIFE

Fig. 1 displays the alterations that happen in bone mass in various stages of women's inhabits, along with the primary influences on those changes. During the first two decades of life, bone grows in both extent and width. From infancy through juvenile adulthood, bone formation predominates over resorption, producing in a steady accumulation of bone mass, in the direction of the formation of PBM. Almost half of the mature individual skeletal mass is profited throughout the pubescent development spurt. Ca balance throughout this time is most positive and varieties from 200 to 300 mg/day [8, 10]. At the completion of puberty, bone extends to boost in width and density into juvenile adulthood, when PBM is achieved. It has been assumed that persons with higher PBM accomplished in early adulthood will be at smaller risk for evolving osteoporosis subsequent ...
