RESUMO
Young's procedure contains an action mechanism that works better than other techniques on the pathophysiology of FFD. It respects the anatomy and biomechanics of the foot to reach the necessary muscular balance. The benefits of this technique include that the ATT is not detached, so its function mechanism is still active; the new trajectory of the ATT provides a powerful sling function at the level of the navicular; and the horizontal trajectory of the ATT and the osteoperiosteal flaps constitute a powerful inner capsulartendinousligamentous support. What is more, an insufficiency of the ATT is created, which results in a predominance of the peroneus lateral longus, that descends and prones the forefoot. Additional procedures, such as medial displacement calcaneal osteotomy, should be considered to correct the entire deformity. The combination of these techniques do not sacrifice the joint mobility.
