POTTENGER93 has made an excellent study of nutritional disturbances in children. He presents an interesting series of roentgenograms which demonstrate alterations in bone structure due to a nutritional deficiency. As the deficiency is remedied, condensation of bone is demonstrable in the roentgenograms. These changes are shown in various stages of growth. In an article for the orthodontists he correlates the changes in the jaw which are due to malnutrition with changes which are seen roentgenologically in the bones of the foot and hand. The roentgenologic changes in the bones of the foot are extremely definite.
[Ed. Note (E. D. W. H.)
—This is a good paper. Orthopedists will be interested in learning more about the work which Pottenger is carrying out. Roentgenologic changes in the foot which are directly related to food deficiency are described as well as the correction of these changes by the administration of proper food.]
