Intoeing is one of the most common reasons for referral of children to orthopaedic evaluation. The most frequent cause is increased femoral anteversion (AV). The AV-angles have traditionally been measured by radiographic methods. In recent years, ultrasonographic techniques for such measurements have been introduced. Relatively liberal indications for surgical correction of increased anteversion by derotational osteotomy have previously been practised in Norway. The indications are now much more restrictive, because several reports have documented spontaneous reduction of the AV-angles during growth. We think operative treatment should be considered if markedly increased AV-angles and serious complaints persist at age 10-12 years.
