M21.07: Valgus deformity, not elsewhere classified Ankle and foot

You have a valgus deformity in your ankle.

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.

The bones and joints are normally in a specific position and at specific angles to one another. With a valgus deformity, the bones or joints are not positioned as normal or not at the usual angle to one another. A valgus deformity in the ankle is also known as skew foot. A skew foot is when the foot is bent outwards at the ankle. A valgus deformity can also affect other bones and joints in the foot.

A valgus deformity can develop when bones are diseased or damaged. A valgus deformity can be painful. You may not be able to move the affected part of your body properly. A skew foot may also cause problems when walking.
