The prototype of developmental deformities is the “club foot”, scientifically called “congenital talipes equinovarus”.

In this pathology, the multiplicity of bones and joints about the foot become evident. It is in fact a tridimensional deformity in which not only the joint axes are malpositioned but also the bones are deformed.

Especially if rigid, the treatment of this deformity is primarily surgical. It is mandatory that the foot that was deformed in utero achieves plantigrade posture under normal weight-bearing conditions at the usual age of walking. The origins of the disease are multiple and the severity of expression of the deformity is very variable.
