title: Evolution of bone disease over 10 years in 135 patients with terminal renal failure.
abstract: An objective radiographic study of erosions, fractures, and periarticular and vascular calcification was made in a series of 135 patients over 10 years of maintenance haemodialysis therapy. The four lesions progressed at different rates, consistent with variation in the response of tissues to a changing biochemical milieu and deficiency in vitamin D metabolites. The half time for development of individual radiographic signs was 3.4 years for vascular calcification, 9 years for fractures, 16 years for periarticular calcification, and 22.9 years for erosions. Calcification of the dorsalis pedis artery seen as a developing ring or tube was an early and valuable sign of disturbed calcium metabolism. In these patients renal osteodystrophy is a chronic condition with a prolonged time course.
