Subtalar Fusion (Arthrodesis)

What is a Subtalar Fusion (Arthrodesis)?

Subtalar fusion is a surgical procedure that involves fusing together two specific bones in the foot: the talus bone and the calcaneus bone. These bones make up the subtalar joint, which plays a role in side-to-side movement of the foot. Subtalar fusion is performed to address certain foot problems, usually when there's severe pain, deformity, or instability in the joint.

The goal of subtalar fusion is to stop the movement between these two bones, which can be causing discomfort or making it hard to walk. During the procedure, the surfaces of the talus and calcaneus bones are prepared and then joined together using screws, plates, or other devices. Over time, these bones grow together, creating a solid connection.

By fusing the subtalar joint, the movement that was causing problems is eliminated, and this often leads to reduced pain and improved stability. After the fusion has healed, the foot might not be as flexible as before, but it can still function well for most daily activities.

Recovery after subtalar fusion involves wearing a cast or boot for a while to protect the healing bones. Physical therapy and exercises are often recommended to help regain strength and adapt to the new foot movement.

Subtalar fusion is usually considered when other treatments haven't provided relief or when there are significant structural issues in the foot.
