Osteoarthritis of the thumb carpometacarpal joint has a reported radiographic prevalence of 7 percent in men and 15 percent in women. Many patients remain minimally symptomatic; however, a subset of patients develop debilitating pain, weakness, and instability that severely limit hand function. Treatment options have focused on removal of the diseased trapezium and stabilization of the metacarpal base. Newer options, including carpometacarpal arthroplasty, may have a role in some patients for improving function. This article explores the anatomy and biomechanics of carpometacarpal arthritis and its present surgical treatment options.
据报道，拇指腕掌关节骨关节炎在男性中的影像学患病率为7%，在女性中为15%。许多患者症状轻微；然而，一部分患者会出现使人衰弱的疼痛、无力和不稳定，严重限制手部功能。治疗选择主要集中在切除病变的大多角骨和稳定掌骨基部。包括腕掌关节置换术在内的新选择可能对一些患者改善功能有作用。本文探讨了腕掌关节关节炎的解剖学和生物力学及其目前的手术治疗选择。
