What are the symptoms of juvenile osteoporosis?

A child with juvenile osteoporosis may complain of pain in the back (lower region), hips, feet, or legs. The child may have trouble walking, develop a limp, and experience fractures in the legs and feet. In some cases, children may also have an unnatural curvature of the upper back. The child may even appear to be shorter than usual. Low bone density is another sign of the disease. Doctors can use tests and scans to study bone mass to determine whether or not loss has occurred.
