Ankle arthrodesis, also known as ankle fusion, is a surgical procedure that involves the fusion of the bones of the ankle joint. The ankle joint is located between the lower leg bones (tibia and fibula) and the ankle bone (talus), and allows for the up-and-down movement of the foot. Ankle arthrodesis is typically performed in cases where the ankle joint has been severely damaged by arthritis, injury, or other conditions, and when non-surgical treatments have been unsuccessful. The goal of the surgery is to provide pain relief and improve stability and function of the ankle. During the procedure, the damaged joint surfaces are removed and the bones are held together with screws, plates, or a combination of both, until they fuse together.
