Residual adduction of the forefoot in treated congenital club foot.

Adduction of the forefoot is recognised as one element of the deformity of club foot. It commands little attention because it is one of the less disabling features, and it has been suggested that spontaneous correction eventually occurs (Wynne-Davies 1964). Metatarsus varus and talo-navicular subluxation, singly or in combination, are the two abnormalities responsible for this deformity. The role of metatarsus varus has not been previously investigated and consequently it is usually regarded as the less important factor. This survey of older children was undertaken to determine the incidence and cause of residual adduction of the forefoot after various conventional methods of treatment of congenital club foot. We emphasise that cases of congenital metatarsus varus as a separate entity were excluded.
