The Wrist Joint Affected by Rheumatoid Arthritis - Computational Biomechanics of the Wrist Joint - page 27

Fig. 3.2 A posterior photograph of patient with rheumatoid arthritis hands (a), note axial
deviation of the wrist and clearer observed as seen in X-ray of the right (b) and left (c) wrist [ 13 ]
both sides of the limb (Fig. 3.2 ). It can either be the same joint in both limbs or
different joints of the same limb. For instance, patient with RA in the wrist has the
same symptoms in the fingers of the same hand.
In conjunction with the pathomechanics of the RA, there are cascade of events
behind it. The disease process commences by mainly affecting the soft tissues
including the adjacent articular cartilage (chondrolysis) then followed by the hard
tissues (bone resorption), thus resulting in severe deformities [ 12 , 13 ] of the joint.
