ABSTRACT
The cavus foot can be treated with the closed method if the skeleton is still actively growing. The closed method is also indicated for mixed (anterior and posterior) cavus deformity or after multiple failed surgical treatments. Cavus foot correction can be compared to the principle of flattening a curved segment (Figure 4.1). By distancing the extremities of the curved segment (lengthening) and simultaneously subjecting them to traction in a cranial direction (straightening) while compressing the top of the curve, the concavity is flattened out. Consequently, it is possible to determine its apex, which, when observed clinically, falls in the proximity of the Chopart joint in the natural anatomical arch of the foot.
