Evidence of rare disease may be useful in the identification of unknown remains. Osteodystrophy is a condition commonly associated with chronic renal failure. The presence of renal osteodystrophy and medical artifacts associated with the treatment of kidney failure in human remains may provide information about the individual's medical history. Currently, there are more than 100,000 patients with end stage renal disease in the United States receiving dialysis treatments to replace kidney function, and hundreds of thousands more who have significant chronic kidney failure and are not yet treated with dialysis. Chronic renal failure frequently leads to disorders in the metabolism of vitamin D, calcium, and parathyroid hormone which are extremely difficult to correct. At least three patterns of skeletal change may result: osteitis fibrosa, characterized by increased bone remodelling, increased osteoclastic activity, peritrabecular fibrosis, and a normal mineralization pattern; osteomalacia, with a markedly increased osteoid surface and volume, and impaired mineralization; and mixed osteodystrophy, with increased bone remodelling and moderately impaired mineralization. While these bone changes may not have any clinical manifestations in most patients, they can been seen radiographically and histologically. This evidence may be useful in identifying remains which have been skeletonized, burned, decomposed, or dismembered. Medical artifacts associated with dialysis treatment, such as catheters, polytetrafluoroethylene grafts, and evidence of surgical procedures, are also useful for identification.
