M07.17: Arthritis mutilans Ankle and foot

You have psoriasis.

Your body’s own immune system plays a role in the development of psoriasis. The condition can be hereditary. Other family members may then be affected, too. Triggers such as skin irritations, stress or certain medications can make the condition worse.

A lot of small, pus-filled pustules have formed on your skin. These pustules can burst on a large scale, and make the skin more susceptible to pathogens. The condition can affect the entire skin. This can make you very sick. The nails may also change.

Psoriasis has caused joint inflammation in your ankle or foot. An inflammation in the joints can cause various symptoms. Typical is a swollen, painful joint. The skin above the joint may also be red. It may also no longer be possible to move the joint as usual.

At their lower end, the two lower leg bones have a bony prominence. These bony prominences on the ankles are called malleolus bones. The ankle joint is between the lower leg and the foot. There is an upper and lower ankle joint. The foot and toes consists of a lot of small bones and joints. At the back is the tarsus, followed by the metatarsus and then the individual phalanges of the feet.
