Estimation of bone turnover in climacteric women by the whole body retention of fluoride.

This paper reports the measurement of whole body retention using fluoride (WBRF) as an estimator of skeletal turnover in a group of climacteric women that received an oral dose of 700 mumol of sodium fluoride. WBRF is defined as 100(1-(urinary fluoride/fluoride load)). WBRF was significantly correlated with whole body retention of 99m-Tc-methylene-diphosphonate, the serum levels of the bone alkaline phosphatase and the urinary excretion of hydroxyproline.
