X-ray of the hands of a patient with psoriatic arthritis. The finger joints have become inflamed and swollen. Psoriatic arthritis is caused by the immune system attacking the body's own tissues, causing progressive joint and cartilage destruction along with scaly skin. As the cartilage is worn away, new bone grows as part of the repair process. This causes stiffness and deformity of the fingers. Treatment is with anti-inflammatory drugs and physiotherapy.
