From an investigation on 400 constitutional diseases of the skeleton foot deformities occur with a frequency of 18%. The most common deformity is represented by congenital clubfoot (14.7%), syndactyly (14.50%), brachydactyly (11%); follow the congenital flat foot (8.75%), Polydactyly (6.25%) and oligoectrodactyly (4.50%); unusual finding of congenital metatarsus varus (3.75%), congenital hallux valgus (2.00%) and hammer toe (2%); rare congenital talipes (1.75%), congenital hollow foot (1.25%) and congenital hallux varus (1.25%); very rare macrodactily (0.75%) and clinodactyly of the fifth finger (0.75%). The majority of diseases that are the basis of the deformities of the foot above are of genetic origin; they recognize an autosomal recessive trans4ission in the 41.12% and dominant in the 31.67%; a dominant X-linked transmission in 4.72% and recessive X-linked in 1.45% ; finally, they are transmitted in different ways with both dominant and recessive in the 7.88% of cases; forms of genetic origin are therefore 86.84% of all cases. 7% is represented by chromosome aberrations and the remaining by embryo-fetopathy or disease of unknown etiology.

Abstract
From an investigation on 400 constitutional diseases of the skeleton foot deformities occur with a frequency of 18%. The most common deformity is represented by congenital clubfoot (14.7%), syndactyly (14.50%), brachydactyly (11%); follow the congenital flat foot (8.75%), Polydactyly (6.25%) and oligoectrodactyly (4.50%); unusual finding of congenital metatarsus varus (3.75%), congenital hallux valgus (2.00%) and hammer toe (2%); rare congenital talipes (1.75%), congenital hollow foot (1.25%) and congenital hallux varus (1.25%); very rare macrodactily (0.75%) and clinodactyly of the fifth finger (0.75%). The majority of diseases that are the basis of the deformities of the foot above are of genetic origin; they recognize an autosomal recessive trans4ission in the 41.12% and dominant in the 31.67%; a dominant X-linked transmission in 4.72% and recessive X-linked in 1.45% ; finally, they are transmitted in different ways with both dominant and recessive in the 7.88% of cases; forms of genetic origin are therefore 86.84% of all cases. 7% is represented by chromosome aberrations and the remaining by embryo-fetopathy or disease of unknown etiology.
