Finite Element Analysis of the Wrist Joint Affected by Rheumatoid Arthritis - Computational Biomechanics of the Wrist Joint - page 54

Fig. 5.13 The average contact pressure in each bone of the healthy and RA model

Fig. 5.14 Stress distribution in the forearm (the radius and ulna) for the healthy (a) and RA
model (b). Two critical articulations were identified; radioscaphoid and radiolunate. It was also
observed that existence of sharp edges at the RA model resulted in high stress concentration
