Anterior ankle fusion is an open surgical procedure that fuses or joins the ankle bones together.

The ankle is the joint that connects the leg in the foot, the ankle joint includes the two lower leg bones called the tibia and fibula. And the ankle bone is called the talus.

tibia and fibulaTalus (ankle)

Together the ends of the tibia and fibula create a mortise or slot for the talus which forms the bottom of the ankle joint. Tissues called ligaments and tendons support the ankle bones ligaments attach bone to bones and tendons attach muscles to bones.

The ankle joint allows the foot to move up and down.

Articular cartilage on the ends of bones is a smooth gliding covering that allows fluid joint movement.

What is Ankle Fusion?

Ankle fusion also known as arthrodesis is a surgical procedure that joins the ankle bones together, so they no longer move or rub against each other.

Doctors may recommend this procedure for conditions that lead to severe ankle joint damage and pain.

The most common condition is osteoarthritis also known as degenerative joint disease.

In the late stage of osteoarthritis, the cartilage covering the ends of the bones has worn away exposing bare bone.

This along with the growth of bony projections called bone spurs causes swelling pain and limited movement of the joints.

Another condition that may require ankle fusion is rheumatoid arthritis, where the patient’s own immune system attacks the joints.

Any condition that destroys the joint surface such as a severe bone infection or death of bone tissue called osteonecrosis. May also require fusion of the ankle joint.
