What Is Hammertoe? Hammertoe is a contracture (bending) deformity of one or both joints of the second, third, fourth or fifth (little) toes. This abnormal bending can put pressure on the toe when wearing shoes, causing problems to develop. Hammertoes usually start out as mild deformities and get progressively worse over time.
