Oxalosis of bone is caused by a combination of crystalline calcium oxa
late deposition in bone and renal osteodystrophy in patients with chro
nic renal failure. The present paper presents the radiographic finding
s of oxalosis of bone in four patients who have been followed over a p
eriod of from 4 to 16 years. Four successive characteristic stages can
be recognized in the development of the skeletal changes.
