Symptoms of mild clubfoot include toes on the ground when standing, heel dangling, unsteady walking, kicking and claudication. In mild clubfoot, the metatarsal surfaces of the foot may be folded, with elastic resistance to dorsiflexion and abduction, and the anterior portion of the foot may be inwardly retracted and pendulous. When standing, the performance is that the toe of the foot is on the ground, but the heel is hanging in the air, like a horseshoe; when walking, the performance is that the walking is unstable, limping, the outer edge of the foot is on the ground, the toe of the foot can not be lifted up when the foot is off the ground, kicking the ground, the toe of the foot before the foot follows the ground, and so on. Long-term deformity can be aggravated, muscle atrophy. Horseshoe foot can be seen in congenital deformity, polyneuritis, spina bifida, spastic paralysis of the lower limbs, sequelae of poliomyelitis, ankle disease, long-term bedridden patients and lower limb fracture improperly fixed. Usually, the earlier the horseshoe foot is treated, the better the therapeutic effect, so it is recommended to treat it as early as possible.
