Congenital metatarsusadductus presents as an inversion and inversion of the forefoot at the accessory joint. The deformity is completely in front of the ankle joint, while the heel remains in a normal relationship with the lower leg. Pathogenesis: Most of the deformities are caused by genetic factors, but some scholars believe that they are caused by the malposition of the fetus in the womb. The deformity is not always obvious at birth, and Kite reported that only 1/3 of the cases were detected at birth, and the rest were diagnosed at an average of 2 or 8 months after birth. Congenital plantar entropion can also occur with other congenital malformations. The first type is the most common, with the forefoot inward, turned inward, rotated back, high longitudinal arch, projection of the outer edge of the foot, depression of the inner edge, neutral position of the heel or slightly turned outward, and widening of the gap between the toe and the second toe. The toe alone is more mobile, suggesting a reversion phenomenon. 2, Type 2 is a deformed foot after conservative treatment, part of the deformity has been corrected, but some forefoot inversion and inversion at the mid-tarsal joint remains. 3.The third type is mainly manifested as forefoot valgus and varus, metatarsal inversion, and fixed heel valgus deformity, mostly with genetic factors. Treatment principles of the first type of children preferred to correct the manipulation, the general effect is good, and then choose surgery if not effective. Manual correction of the physician thumb to push the dice bone inward, the other hand holding the forefoot abduction, valgus, and then wear orthopedic shoes can be; for the more serious can be supplemented with plaster or brace treatment. For the second and third type of non-surgical treatment is difficult to see the effect, the need for surgical release of soft tissue to correct the deformity, the deformity is serious for larger children need to perform osteotomy orthopedic surgery. Surgical treatment methods 1, soft tissue surgery: 2, osteotomy surgery.
