A hammer toe is a toe that is bent because of a muscle imbalance around the toe joints. The imbalance causes the toe to bend at one or more joints, pushing the middle of the toe upward in a claw-like position. Hammer toes always occur in the four smaller toes, usually the second toe. They may hurt or look odd, or both.
If you notice such changes in your toe, it is important to seek proper treatment. Hammer toes never get better without some type of intervention and the sooner it is treated, the better the outcome.
