This is a surgical procedure which joins together the main bones of the ankle joint (the tibia and the talus). However, depending on the technique your surgeon will use, occasionally the fibula will be included in this procedure.
The two joint surfaces which generate the pain are removed. The joints are then fused together with screws.
In an ankle fusion the joints each side from the fused joint can take over some of the original function of the affected joint.
The good news is that once the ankle has fused you will be able to return to most of your pre-operative activities.
