What complications can arise from psoriatic arthritis?
In rare cases, psoriatic arthritis may progress to its more serious subtype, known as arthritis mutilans. This condition causes the small bones in the hands to wear away over time, resulting in permanent deformity and disability. Psoriatic arthritis may also affect quality of life or cause psychological effects, such as distress, low self-esteem, depression or embarrassment. It may also increase the risk of developing osteoporosis.
