Osteoarthropathy of patients undergoing long-term hemodialysis.
Maintenance hemodialysis, while capable of prolonging life, is an incomplete substitute for the patient's native functioning kidneys. Recently, it has become clear with time that long-term survivors of hemodialysis develop an osteoarthropathy differing from classic secondary hyperparathyroidism. The radiographic appearance includes erosive or destructive changes of articular surfaces, bone cysts, osteopenia, and periarticular calcific deposits. The most important clinical factor related to the development of the disease is increasing duration of hemodialysis. Although amyloid appears to be a causative factor, the exact etiology and treatment remain uncertain. It is important that the radiologist be aware of this entity and not mistake it for secondary hyperparathroidism, a variant of rheumatoid arthritis or infection.
