[Dudley Joy Morton's foot syndrome].

Morton's foot syndrome is a hereditary syndrome characterized by a short first metatarsal bone, posterior displacement of the sesamoids, and hypertrophy of the second metatarsal, causing excessive weight to be borne by the second metatarsal head. This condition results in callus formation under the second metatarsal. Pain and tenderness are usually felt at the base of the first two metatarsal bones and at the head of the second. Pain (metatarsalgia) may be disabling. Conservative treatment consists of placing a flexible pad under the first metatarsal and toe to increase the range of motion and weight-bearing along the first metatarsophalangeal joint and the hallux. Surgical treatment consists of removing a small portion of bone from one or two joints to bring the toe down to the desired length. Lengthening short toes by placing a silicon implant into one of the joints is also possible.
