The shoulder pain syndrome and soft-tissue abnormalities in patients on long-term haemodialysis

Abstract

Fifteen patients on long-term haemodialysis were studied. Twelve patients were symptomatic and ten of these patients had shoulder pain. Eleven patients had associated carpal-tunnel syndrome. A statistically significant correlation was observed between the soft-tissue abnormalities of the hands, carpal-tunnel syndrome and the shoulder pain. Radiological changes were also common and were noted in 14 patients; cysts and erosions were the commonest. The shoulder joint was the most commonly involved joint. No obvious correlation existed with either raised parathormone or calcium levels. The possible role of beta 2-microglobulin and associated amyloidosis in the causation of this syndrome is discussed.
