OBJECTIVES: I. Determine the effects of alendronate sodium on skeletal remodeling and bone mineral density of the hip and spine in children with high-turnover idiopathic juvenile osteoporosis.

Study summary:

PROTOCOL OUTLINE: Patients receive oral alendronate sodium weekly for 1 year. Treatment continues in the absence of disease progression or unacceptable toxicity.
