Torsion of the Femur

A twenty-year follow-up on the use of the Dunlap-Shands method for the determination of torsion of the femur is presented, with the results of a total of 1,990 torsion studies in normal children and children with congenital dislocation of the hip, coxa plana, toeing-in, and cerebral palsy. The effect of increased anteversion is discussed as it relates to each hip condition discussed. Increased anteversion should be considered a very significant factor in the treatment of many hip conditions.
