Arthritic deformity


Arthritic deformities are caused by rheumatoid arthritis which can damage bones, joints and tissues of the foot. Rheumatoid arthritis is a chronic disease that causes inflammation of the joints.


Arthritic deformities of the foot have a variety of symptoms including:

  • Pain and swelling
  • Reduced function of the foot
  • Difficulty walking
  • Tenderness of the joints
  • Bunions and hammer toes
  • Dislocation of toe joints
  • Claw-like appearance of toes


Rheumatoid arthritis causes toe joints to swell which can lead to the destruction of the joints of the foot and arthritic deformities. As the lining of the joints becomes inflamed, joints fill with fluid and become painful. Deformities are a result of the loosening of the ligaments and the capsule lining of the joints. In some cases, the joints may dislocate.
