[Research progress in artificial metacarpophalangeal joint and interphalangeal joint prostheses].

To summarize the research progress in artificial metacarpophalangeal joint and interphalangeal joint prostheses. The research literature on artificial metacarpophalangeal joint and interphalangeal joint prostheses at home and abroad was reviewed and summarized from anatomy, prosthesis design, and material development. The artificial joint replacement can correct deformity, relieve pain, and improve function immediately. In the past 50 years, many researches have focused on the design and material of prostheses and surgical technique of joint replacement. There are three types of prostheses, including hinged limit-type-prosthesis, semi-limit-type-prosthesis, and non-limit-type-prosthesis. The prostheses have their own advantages and disadvantages, the long-term effectiveness of joint replacement is not ideal. The metacarpophalangeal joint and interphalangeal joint prostheses with more anatomical structure and biocompatible materials are needed. 总结人工掌指及指间关节假体的研究进展。. 查阅近年国内外有关人工掌指及指间关节假体的研究文献，并从解剖学研究、假体设计及材料发展三方面进行总结。. 人工掌指及指间关节置换术能即刻纠正手指畸形、缓解关节疼痛并改善功能。近五十年来，学者们对掌指及指间关节假体设计、假体材料、手术方式等方面进行了大量研究，目前临床应用的假体包括铰链式限制型假体、半限制型假体、非限制型假体 3 类，均有其优缺点，但远期疗效均不理想。. 目前人工掌指及指间关节假体尚未达到理想效果，临床需要更符合解剖结构、更具有生物相容性材料制备的假体。.
