Abstract
Twenty eight patients who had received haemodialysis for more than 10 years were reviewed to establish the incidence of joint problems. Only six patients had no joint symptoms, one had avascular necrosis, one had had recent septic arthritis, and four had hyperparathyroidism. The remaining 16 patients had no evidence of hyperparathyroidism yet had an arthropathy causing pain and stiffness in many joints, particularly the shoulders. Ten of these 16 patients had a recurrent carpal tunnel syndrome requiring repeated surgical decompressions, which resulted in only partial improvement. Of the eight patients who had received dialysis for more than 15 years, seven had this "dialysis arthropathy" and six had recurrent carpal tunnel syndrome. Dialysis arthropathy is a common and often severe and disabling complication of long term treatment with haemodialysis. The cause is not known, but amyloid was found in a synovial biopsy specimen from one patient.
