[Patterns of localization and process in age induced bone atrophy and pathological osteoporosis (author's transl)].

Dennert and Münzenberg recommend comparative examination of x-rays of the spine and coxal end of the femur both for the differentiation of physiological bone atrophy and pathological osteoporosis and for the gradual evaluation of osteoporosis. The systematic bone deterioration in the proximal section of the femur in physiological osteoporosis is absent in the pathological forms of osteoporosis where only the skleletal trunk is usually involved. Since quantitative examination procedures for the exact differenciation of osteoporosis are generally not available for the practice, the comparative examination represents an essential help for diagnosis and the gradual evaluation of osteoporosis. To support the interpretation of the findings from this procedure which is well suited for the practice, the chronological and local process of physiological and pathological osteoporoses (obtained by quantitative radiological measurements) are compared.
