Association of childhood fractures with osteoporosis of the elders: a coincidence or a forecast?

Bone fracture occurs nearly in half of the children. Some fractures are severe traumatic events while others are the results of genetic or hormonal or other alterations disturbing the normal development of bone. However, the majority of fractures are associated with a mild trauma, dominantly in the pubertal period. The basic pathology of the pubertal fractures is the transient deviation of peak velocity of height growth from the gain velocity of bone mass; the latter goes to peak 1 year later than height growth. This difference has been resulted in a physiologic but transient weakening of bones that can coincide with genetic, hormonal or life-style problems and all of these factors together may cause the increased fragility of the pubertal bone. Low-trauma fractures in childhood may be followed in high fracture risk of adult and aging men, so the childhood fracture seems to be a useful screening question for testing the osteoporosis in males. However, the same relation is still not proved in aging women.
