Rheumatoid arthritis
can be a severe debilitating disease crippling feet. Women seem to be more affected then men.
RA can
affect the foot in similar fashion as the hand, ulnar deviation --> fibular deviation. RA classically will have joint
destructive changes and eventual joint ankylosis. Medial joint pannus with cystic erosions are classically seen at the
MPJ's.
RA patients are easy to spot, severe bunion and hammertoe deformities. Often toes are dislocated.
Patients often feel and look like they are walking on glass.
RA can often affect the rearfoot and ankle.
Oddly, the talonavicular joint is often involved more frequently.
