Bone disease in long-term haemodialysis: the association of radiological with histological abnormalities.

The radiological findings in the skeletal surveys of 70 patients receiving long-term haemodialysis for chronic renal failure have been correlated with histological findings in a specimen obtained by biopsy of the iliac crest. Many significant associations were found, and the ones presented are those thought to be most useful in the interpretation of the radiological abnormalities. The main conclusions are that fractures and severe medullary rarefaction appear to be most commonly the result of osteomalacia; subperiosteal erosions are associated with the more severe grades of osteitis fibrosa; cortical striations and sclerosis are associated with an increased amount of osteoid, and sclerosis is diagnosed more frequently by radiological means than by iliac-crest biopsy.
