RENAL OSTEODYSTROPHY IN PATIENTS ON HEMODIALYSIS AS REFLECTED IN THE BONY PELVIS

¹ Department of Radiology, Henrotin Hospital, Chicago, Illinois.

Roentgen studies in a group of 131 patients on maintenance hemodialysis reveal renal osteodystrophy in 25 patients (19 per cent). In 24 patients of the latter group (98 per cent), the various manifestations of renal osteodystrophy appear in the bony pelvis. They include: osteomalacia; osteitis fibrosa; osteosclerosis; dialysis osteopenia; and extraosseous calcifications. Some of the changes, i.e., bending of bone, Looser’s lines, metaphyseal fractures and dialysis osteopenia, are due, at least in part, to the weight bearing nature of the bony pelvis. These findings are rarely, if ever, seen in the digits or in other non-weight bearing bones.

It is therefore proposed to evaluate the bony pelvis, together with the magnification digital roentgenogram, when a less costly and less time consuming skeletal survey is needed in hemodialized patients.
