Hammer toe is a deformity of the toe where there is an abnormal bend in the middle joint, causing the toe to bend downward instead of pointing straight. This condition can be caused by wearing ill-fitting shoes, muscle imbalance, arthritis, or genetics. Symptoms may include pain, corns, calluses, or difficulty moving the affected toe. Treatment options include wearing properly-fitted shoes, toe splints, exercises to stretch and strengthen the toe muscles, and in severe cases, surgery to realign the toe joint. Early intervention is crucial to prevent the deformity from worsening.
