Idiopathic juvenile osteoporosis is a primary condition with no known causes. This rare form of osteoporosis typically occurs just before the onset of puberty in healthy children, who have regular amounts calcium, vitamin D, and hormones and have no reason to lose bone density. The average age at onset is 7 years old, with a range of 1 to 13 years. The good news is that most children experience complete recovery of bone.
