Trapeziometacarpal joint osteoarthritis is a common radiographic finding, particularly in postmenopausal women, though in most cases it is painless. Its prevalence is increasing in an alarming manner with the aging of the population. This increase is somewhat frightening considering that osteoarthritis is associated with numerous adverse consequences for the affected individuals as well as increasing economic costs for society. It can have substantial effects on the stability of the trapeziometacarpal joint, causing pain and reducing the capacity to perform daily activities. Some studies have revealed only a weak association between trapeziometacarpal osteoarthritis radiographic findings and clinical symptoms. The diagnosis is mainly based on a careful medical history and clinical examination.
