You had an operation to stiffen your ankle.

At their lower ends the tibia and fibula form the malleolus bones in the ankle. At the top of the ankle the lower ends of the tibia and fibula are connected to a bone at the back of the foot. The bone at the upper rear of your foot is called the talus, and it is part of the upper and lower ankle joint. The lower ankle joint sits beneath the talus. The lower ankle joint is made up of the talus, the calcaneus and other bones in the foot. The calcaneus is the bone at the lower rear of the foot that you can feel in your heel.

A damaged ankle joint can cause various discomforts. To prevent discomfort, the joint can be stiffened in a favorable position. This should enable you to be able to use your foot better.

You had an operation to set bones in your upper and lower ankle joint into a favorable position and connect them firmly together. Screws, staples or bone material, for example, can be used to do this. The bones can also be further stabilized so that they fuse together.
