Study and computer-aided analysis of artificial human wrist

Abstract

The wrist joint is frequently affected by rheumatoid arthritis, resulting in wrist pain, deformity and ultimately loss of function. Artificial wrist implants have been introduced to treat the rheumatoid wrist, to attempt to alleviate pain and restore some function to the joint. This paper describes the anatomy of wrist and the design of an artificial wrist design. The artificial joint part consists of two parts, which are distal part and radius part. Computer aided engineering design is being used and help engineers quickly build up three-dimension model. Besides, Computer aided analysis and simulation have been set up to analyze the stress and total deformation.
