Calcium metabolism was studied in a 12-year-old girl preseting with idiopathic juvenile osteoporosis. Absorption of orally administered 47-Ca was high. Serum calcium and phosphorus, serum immunoreactive PTH and CT and tubular phosphate reabsorption were found to be within normal limits. The data suggest that calcium malabsorption, nutritional calcium deficiency, hyperparathyroidism, a dysfunction related to sex hormones, and Cushing's syndrome cannot be implicated in the aetiology of the osteoporosis in this case who recovered spontaneously with sexual maturation.
对一名患有特发性青少年骨质疏松症的12岁女孩的钙代谢情况进行了研究。口服47 -钙的吸收量较高。血清钙和磷、血清免疫反应性甲状旁腺激素（PTH）和降钙素（CT）以及肾小管磷重吸收均在正常范围内。数据表明，钙吸收不良、营养性钙缺乏、甲状旁腺功能亢进、与性激素相关的功能障碍以及库欣综合征均与该病例骨质疏松症的病因无关，该病例随着性成熟而自发康复。
