Hammertoe is a deformity that causes one or more toes to bend or curl downward instead of pointing forward. Treatment options may include strengthening and stretching the toes through toe exercises, wearing shoes with a roomier toe box, and using orthotic devices. In severe cases of a painful or arthritic hammertoe, surgery may be necessary to remove the bone bump or straighten the toe. Recovery from surgery can take several weeks, during which you may need to wear special shoes to protect your toes.
