Pathology of congenital metatarsus varus and its relationship to other congenital deformities of the foot.
Congenital metatarsus varus may be regarded as a deformity caused by a dislocation and in that respect is similar to congenital clubfoot and vertical talus but not to calcaneovalgus. The dislocation causes adaptive bone changes as well as secondary contracture of the soft tissues. That the dislocation in the forepart of the foot may occur in a maximally dorsiflexed foot also may explain the valgus position of the hindfoot. The secondary changes in bone and soft tissue may explain the lack of spontaneous recovery and the difficulties in effecting correction in severe cases. It is still not possible to explain why the dislocation arises.
