Angular and torsional deformities of the lower limbs in children.

Angular and torsional malalignments of the lower extremity in children are common problems for which parents seek orthopedic advice. Calcaneal valgus of the foot, internal tibial torsion, genu varus, genu valgus, and femoral anteversion are normally observed in infants and usually are corrected with growth. The majority of angular deformities are physiologic; however, it is important to distinguish those requiring further evaluation and treatment. Accurate examination and knowledge of the natural history of rotational and angular deformities allow accurate assessment of the child and sound advice to the parents. There is a trend away from the use of shoe modifications, Denis-Browne-type bars, and twister cables in treating these deformities. Surgical treatment is occasionally required, but the prerequisites in each case should be carefully observed.
