Hammer toe is a claw-like deformity in which the end of the toe is bent downward. It usually affects the second toe, although it can affect other toes. Its causes can be muscular or because of pressure from a bunion.
The pain that results from hammer toe can be prevented by wearing comfortable footwear - but some cases of the condition may require a surgical solution.
Getting treatment for associated conditions, such as bunions, can help stop hammer toe from occurring. Your GP or podiatrist can provide advice, especially if the condition is a result of a structural problem in the foot brought about by something like rheumatoid arthritis.
