The aim of foot fusion surgery is the permanent fusion of separate bones in the foot. This procedure is used to treat flat feet, arthritis, including rheumatoid arthritis, and fractures that haven’t healed of their own accord, or that are caused by wear-and-tear of cartilage and bones over time.
When midfoot fusion is carried out, it can involve one or two bones being joined together, or all the midfoot joints that comprise the foot’s arch. The midfoot’s bones are stiff by their nature, functioning to strengthen and support the foot. Therefore, when they are fused, it doesn’t usually affect movement adversely.
