What is a hammer toe?
Hammer toe is a contracture of the little joints (interphalangeal joints) of the toes and is common in the second, third, fourth, or fifth toes. The claw-like deformity can cause abnormal pressure on the toe when wearing shoes, causing problems to develop.
Hammer toes usually start out as a flexible deformity with mild to no symptoms that can often be managed with non-invasive measures. Because of the progressive nature of hammer toes, hammer toes get progressively worse over time. If left untreated, hammer toes can become more rigid and will not respond to non-invasive, conservative treatment.
