Ankle fusions are performed for two main reasons:
- Ankle arthritis, either due to osteoarthritis or due to rheumatoid arthritis.
- Severe deformity or instability of the ankle joint.
Though some patient may be offered the option of an ankle replacement. It is not an option for all patients especially if:
- You are young (usually under 50) or very physically active.
- You have a severe foot deformity.
- Your ankle is very unstable.
- You have had an infection in the ankle or the bones around it.
- The bone under the ankle (the talus) has collapsed.
Here, an ankle fusion would be advised. If you have a severe foot deformity, you may be advised to have this corrected at the same time as your ankle fusion by fusing other joints in the foot. This would be discussed at the same time as your ankle fusion
