Carpal tunnel syndrome in patients on haemodialysis

Eight cases of carpal tunnel syndrome are reported, all of which developed in patients on haemodialysis for chronic renal failure. In each case the arm involved had been used for a fistula. The aetiology of the syndrome in these patients is discussed; it is multifactorial, but related to the sites of arteriovenous fistulae. Decompressing the carpal tunnel provides effective and lasting relief.
