Unlike the flexible flat foot that is commonly encountered in young children, congenital vertical talus is characterized by presence of a very rigid foot deformity. The foot deformity in congenital vertical talus consists of various components, namely a prominent calcaneus caused by the ankle equines or plantar flexion, a convex and rounded sole of the foot 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 foot's resemblance to the bottom of a rocking chair.[1][2] 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.[1]

It can be associated with Edwards' syndrome (trisomy 18), Patau syndrome (trisomy 13), Trisomy 9 and mutation in the gene HOXD10.[3]
