OSTEOPOROSIS ASSOCIATED WITH LOW SERUM PHOSPHORUS AND RENAL GLYCOSURIA

Abstract

WE ARE presenting the history and investigations concerning a patient with progressive decalcification, a low serum phosphorus content and renal glycosuria. The findings suggest that a physiologic defect of the renal tubules is the primary cause for certain osteoporotic conditions of obscure origin. REPORT OF A CASE D.
