Longitudinal epiphyseal bracket of the first metatarsal, also known as enclosed is a rare congenital disorder characterized by an abnormal development in length metatarsal ray because asymmetric presence longitudinal bracket. This causes interruption lengthways affected bone, which becomes squat and short, with trapezoidal or triangular shape, leading to hallux varus deformity. First occurs 2% 14% all defects hands feet; bilateralism 75% cases greater incidence male patients. The deformity classified differentiation defect; it frequently associated abnormalities such syndactyly polydactyly. There are different surgical treatments reported literature. Most them aimed at excision before complete skeletal maturity year life promote normal growth bone. In this study, authors present three bilateral treatment, lengthening using Penning Minifixator, was instead carried out end growth. approach allowed planning operation involving both structures surrounding soft tissue.
