Objective:
To summarize the research progress in artificial metacarpophalangeal joint and interphalangeal joint prostheses.
Methods:
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.
Results:
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.
Conclusion:
The metacarpophalangeal joint and interphalangeal joint prostheses with more anatomical structure and biocompatible materials are needed.
