Since October, 1924, roentgenograms of the legs and feet of more than 500 diabetic patients of Dr. E. P. Joslin have been taken. The present study includes 324 consecutive patients varying in age from 2 to 81 years.
The legs and feet were chosen for study instead of the arms because the vessels of the legs show evidence of sclerosis earlier than those of the arms. Calcification was not always seen in the aorta even when the process was moderately advanced in the vessels of the legs, perhaps partly because of the fact that it is more difficult to detect calcification in the aorta. Dow1 noted in a small series of complete autopsies that the vessels of the lower extremities were more frequently and completely calcified than any others except the abdominal aorta and the common iliacs.
Care must be exercised in the detection of calcified vessels. Flecks of
