Ankle Fusion

Pain caused by ankle arthritis can become severe and unrelenting, greatly impacting one’s quality of life. An ankle fusion, also called ankle arthrodesis, aims to relieve the pain and maintain or improve function by fusing two or more bones in the ankle. This procedure can help treat a number of different underlying problems in the foot by limiting mobility in the joint. Whatever the cause, no one should have to suffer debilitating pain. The highly-skilled orthopedic specialists at Advanced Orthopedic & Sports Medicine Specialists in Denver, Parker, or Aurora, Colorado, have vast experience treating all conditions of the ankle and foot and can get you treatment to help you get back to life.

OVERVIEW

Ankle fusion is for people who want a permanent solution to their ankle pain so they don’t have to think about it again. It is also recommended to people for whom total ankle replacement is not an option. Ankle fusion has also become a more popular way to treat end-stage ankle arthritis in younger adults. It’s a way to save the ankle and preserve some function. Thus, the operation is also called a salvage procedure. By fusing the bones, an ankle fusion stops the ankle joint from moving at all. It takes a stiff, painful ankle and converts it to an unbending, relatively painless, or in some cases totally pain-free ankle. An ankle fusion can often last a lifetime compared to a total ankle replacement.

ABOUT THE ANKLE JOINT

The ankle joint is a complex mechanism. It is also called the tibiotalar joint, and although typically referred to as a single joint, it is actually two joints; the subtalar joint and the true ankle joint. The true ankle joint is composed of three bones: the lower end of the tibia (shinbone), the lower end of the fibula (the smaller bone of the lower leg), and the talus (the bone that fits into the socket formed by the tibia and fibula and rests on the heel bone). It is responsible for the up-and-down motion of the foot. Beneath the subtalar joint is the second part of the ankle, composed of two bones: the talus on top and the calcaneus on the bottom. The subtalar joint allows side-to-side motion of the foot. The ends of the bones are covered by articular cartilage. The space in the joint is lined with a thin membrane called the synovium, which cushions the joint and secretes a lubricating fluid called synovial fluid. These components of the ankle, along with the ligaments, muscles, and tendons of the lower leg, work together to handle the stress the ankle endures when walking, running, and jumping.

ANKLE ARTHRITIS SYMPTOMS

The ankle is the least likely area of the body to be affected by arthritis. Ankle arthritis happens when there is a breakdown of the cartilage that covers the ends of the bones that form the joint. Moving the arthritic ankle tends to make the pain worse. There are three main types of ankle arthritis:

  • Osteoarthritis, which develops from wear and tear on the joints over time
  • Post-traumatic arthritis occurs after a significant ankle injury, such as a fracture
  • Rheumatoid arthritis is an autoimmune disease that damages the joints.

Symptoms usually develop gradually and worsen with time and overuse. These include:

  • Pain with motion
  • Pain that flares up with vigorous activity
  • Tenderness when pressure is applied to the joint
  • Joint swelling, warmth, and redness
  • Increased pain and swelling in the morning or after sitting or resting
  • Difficulty in walking due to any of the above symptoms

WHAT IS AN ANKLE FUSION?

Ankle fusion involves cleaning the worn-out ankle joint and fusing the tibia and talus bones together with screws, plates, and bone grafts. By doing so, the bones are stabilized and can no longer rub together, reducing pain. Fusion of the ankle does result in the loss of approximately 75% of ankle motion, but some motion is kept through the joints underneath the ankle and into the mid-foot. The limited mobility can change how you walk, and that can cause wear and tear and, ultimately, painful arthritis in other parts of your ankle, knee, and foot. Recovery is longer with ankle fusion than with ankle replacement.
