[Congenital posteromedial angulation of tibia and fibula.].

The author has based his article on all available literature dealing with a rare congenital clinical unit "congenital posteromedial angulation of tibia and fibula". Congenital kyphoscoliosis of tibia is a synonym for the same disease. In contrast to other angulations of the tibia and fibula the above mentioned clinical unit is characterized by a spontaneous remodeling of the bone deformity. Persisting is only the shortening of tibia. The author describes in the study his own follow-up of four cases. In one case it was necessary to correct valgus deformity of tibia in 8th month of age. Angulation in all four children spontaneously corrected itself before the 3rd year of age. Documentation is supplemented with a developmental series of x-rays in both projections. The medial component of angulation persists longer than the dorsal component. Discrepancy of the length of lower limbs in our cases where the growth has not finished yet ranges between 2-4 cm. Key words: congenital posteromedial angulation of tibia and fibula.
