Fusion
Sometimes flatfoot is stiff or there is also arthritis in the back of the foot. In these cases, the foot will not be flexible enough to be treated successfully with bone cuts and tendon transfers. Fusion (arthrodesis) of a joint or joints in the back of the foot is used to realign the foot and make it more "normal" shaped and remove any arthritis. Fusion involves removing any remaining cartilage in the joint. Over time, this lets the body "glue" the joints together so that they become one large bone without a joint, which eliminates joint pain. Screws or plates hold the bones in places while they heal.
