[Physiological changes of mineral content of radius and ulna in relation to age and sex (author's transl)].

The mineral content of the radius and the ulna was measured in 773 persons using 125J photon absorptiometry. Statistical evaluation of the data has provided normal values of mineral content of the forearm bones in men and women between the ages of 15 and 90 years. The course of the mineral content curve is discussed in relation to age and sex.
