INITIAL RESEARCH ON THE BIOMECHANICAL FEATURES OF THE TRIANGLE FIBROCARTILAGE IN HUMAN WRIST

Abstract

Fibrocartilage in the wrist joint is a structure common to both distal radioulnar and wrist joint. It works to cache direct pressure between head of ulna and wrist bones and to disperse the load. The structure is susceptive to acute and chronic strain due to the stretch, pressure and shearing during movement. It is significant for further research on physiological function and injury mechanism of the fibrocartilage to obtain the biomechanical parameters and the relevant constitutive equation of it.
