The carpometacarpal joint of the thumb pollexalso known as the first carpometacarpal joint, or the trapeziometacarpal joint TMC because it connects the trapezium to the first metacarpal bone, plays an irreplaceable role in the normal functioning of the thumb. The most important joint connecting the wrist to the metacarpus, osteoarthritis of the TMC is a severely disabling condition; up to twenty times more common among elderly women than in average.
