Unlike the flexible flat<unk>  that is commonly encountered in young children, congenital vertical talus is characterized by presence of a very rigid<unk>  deformity. The<unk>  deformity in congenital vertical talus consists of various components, namely a prominent calcaneus caused by the ankle equines or planter flexion, a convex and rounded sole of the<unk>  caused by prominence of the head of the talus, and a dorsiflexion and abduction of the forefoot and midfoot on the hindfoot. It gets its name from the<unk> 's resemblance to the<unk>  of a rocking chair. There are two subcategories of congenital vertical talus namely idiopathic or isolated type and non-idiopathic type which may be seen in association with arthrogryposis multiplex congenital, genetic syndromes and other neuromuscular disorders. It can be associated with Edwards' syndrome (trisomy 18), Patau syndrome (trisomy 13), Trisomy 9 and mutation in the gene HOXD10.
