Functional disability in the rheumatoid hand.
The investigation of sixty-one rheumatoid patients relates their hand function to measured hand deformity. Certain deformities are related to a reduction in function; others are not. The dominant hand, used more frequently, deteriorates more quickly than the non-dominant. The benefit on hand function of synovectomy is limited in duration and should be accompanied by some procedure to defer or correct deformity. Study of the metacarphophalangeal joints by radiography and at operation shows that degeneration starts where the metacarpal head first loses articulation with the base of the phalanx, and spreads out from there across the metacarpal head as deformity increases.
