Idiopathic juvenile osteoporosis. An unusual cause of back pain in an adolescent.

Idiopathic juvenile osteoporosis represents a rare bone disorder that affects prepubescent children of both sexes. The diagnosis is generally one of exclusion, ruling out other potential metabolic bone diseases. Here, the authors present a representative case of this rare disorder in an otherwise healthy male, along with the clinical history, physical presentation, and review of the available literature. Finally, it is important to note that patients with this disorder often have profound involvement of the spinal column with multiple compression fractures.
