If the pieces of the talus bone stay in position, non-surgical treatment of just a cast and crutches can be used to treat the broken bone.
When the talus bone in the ankle is broken and the pieces aren’t where they are supposed to be, surgery is needed to make sure it heals correctly. The surgeon will use screws and plates to hold the pieces of the bone in the correct positions.
After surgery, you will have a cast and crutches and won’t be allowed to put weight on your foot for several weeks while you heal. You may need physical therapy once the cast is off.
