In the area of the hand the carpo-metacarpal joint of the thumb together with the metacarpo-phalangeal joints is the most important joint according to the function of the hand. Its reduction of movement leads to misfunction of the thumb and the whole hand. Osteoarthritis of that very special joint commonly occurs in females after the menopause. The increasing severeness of the arthrosis is often complicated through pathological positions as well as through contractures (so called Z-deformities). In these patients operative treatment for improvement of function is very often not avoidable. Especially in the elderly patient with reduced manual work the implantation of a cemented carpo-metacarpal prosthesis (created by de la Caffinière) seems to be a useful treatment. As in all cemented implants the disadvantage is the danger of aseptic loosening of the prosthesis.
在手部区域，根据手的功能，拇指的腕掌关节与掌指关节一起是最重要的关节。其活动度的降低会导致拇指及整个手部功能失常。这种非常特殊的关节的骨关节炎常见于绝经后的女性。关节病的日益严重常因病理体位以及挛缩（所谓的Z形畸形）而复杂化。在这些患者中，为改善功能而进行手术治疗常常是不可避免的。特别是对于体力劳动减少的老年患者，植入骨水泥型腕掌假体（由德拉卡菲尼埃发明）似乎是一种有效的治疗方法。与所有骨水泥植入物一样，缺点是假体存在无菌性松动的风险。
