Adduction of the forefoot diagnosed in the young child generally corrects spontaneously. Resistant forefoot adduction is usually combined with a degree of supination of the forefoot and described as congenital metatarsus varus. In true congenital metatarsus varus there is a contraction or shortening of the abductor hallucis muscle and tendon which is considered to be the primary deforming factor. In the early severe or resistant deformity correction can be achieved by either division of the tendon with release of its capsular attachment, or, in the more severe deformity, by complete release of the abductor hallucis muscle from its extensive attachment to bone and soft tissues.
幼儿中诊断出的前足内收通常会自行矫正。顽固性前足内收通常伴有一定程度的前足旋后，被描述为先天性跖内翻。在真正的先天性跖内翻中，拇展肌及其肌腱存在挛缩或缩短，这被认为是主要的致畸形因素。对于早期严重或顽固性畸形，可通过切断肌腱并松解其关节囊附着处来实现矫正，或者对于更严重的畸形，通过将拇展肌从其广泛的骨和软组织附着处完全松解来矫正。
