[Arthrodesis for the treatment of rigid flatfoot].

In the case of a rigid flatfoot deformity, joint-preserving techniques like soft-tissue balancing and osteotomies do not achieve acceptable results. This is the indication for arthrodesis. The selection of the arthrodesis depends on the amount of deformity, localisation of the rigidity and the general health status of the patient. Isolated arthrodesis can be combined with soft-tissue reconstructions. It is functionally advantageous to preserve as many joints as possible.
