Sixty-six haemodialysed (HD) in centre patients (24 h/m2/week, acetate bath, cuprophane membrane), with a mean age of 59.2 years, treated for 16.7 +/- 4.5 years, underwent clinical examination of their hands to determine anatomical and functional alterations. For each hand a functional score was calculated from a medicolegal technique based on sensitivity and angulation amplitude (rating from 0 to 100). Dialysis-related arthropathy (DRA), including carpal-tunnel (CT) syndrome, was scored as well as hand muscle amyotrophia. Trigger fingers, abnormal synovial hypertrophy, and one or more non-functional tendons were found in 15, 26, and 33% of the patients respectively. Thirteen percent had pseudoporphyria. Amyotrophy was moderate or severe in 39%. The global functional score (mean of the two unilateral functional scores) decreased with time spent on haemodialysis and was correlated with the DRA score. The unilateral functional score was linked to tendinous lesions, amyotrophy, and presence of pulses, but not to CT surgery or presence of AV fistula. Hands with ulnar insult at the elbow shown by electromyography had significantly lower functional scores. Repercussions of hand functional alteration may have an important social and psychological impact in daily life. The responsibility of amyloidosis is evidenced by tendinous lesions and nervous entrapment. Ulnar palsy is also important because of the vital motor role of that nerve in hand function.
