[Arthrosis of the first ray of the hand in geriatric patients (author's transl)]

The frequency of arthrosis in the first ray of the hand increases with the age of the patient, particularly in the saddle joint of the thumb and in the joint between the trapezoid bone and the navicular bone of the hand. The finding is frequently bilateral and is accompanied by kinesalgia, periarticular swelling and restricted movement. A relationship between arthrosis of the first ray of the hand and certain occupations can be assumed. While the arthrosis in the saddle joint of the thumb demonstrates the usual radiological symptoms of arthrosis, the sclerosing of the joint surfaces between the os naviculare and the ossa multangula is the most pronounced.
