Abductus valgus flat foot is the most common hind foot deformity in patients with rheumatic diseases. When conservative treatments (insoles and orthopaedics shoes) are not enough, surgery can be a good option. If only the talonavicular joint is affected, it can be fused. If hind foot valgus deformity is reductible, we perform a posterior tibial tendon repair associated to subtalar joint arthoereisis with an endorthesis. If hind foot deformity is severe and non-reductible, we fuse the talonavicular and subtalar joints through a double approach. We usually leave the calcaneocuboid joint not fused.
