Club foot revealing a hypoplasia of the navicular bone: the first case report.

Congenital orthopaedic disorders are not infrequent. Even though some orthopaedic disorders are immediately obvious at birth (such as congenital talipes equinovarus [CTEV]), others are not apparent or may even be hidden (such as congenital bone hypoplasia). This means that a comprehensive orthopaedic examination is of great value when screening for congenital orthopaedic disorders [7]. Congenital talipes equinovarus is one of the most frequent congenital orthopaedic disorders. It may occur alone or in combination with other malformations. However, an association with hypoplasia of the navicular bone has never previously been described. Here, we report on a case of unilateral hypoplasia of the navicular bone discovered during the treatment of CTEV.
