Non displaced fracture, ankle w/ space in fibula. cast removed, no boot ordered told to walk. dr; if gap doesn't close will rebreak and plate. advice?

Fibula fracture: Does not sound like the fracture is healed yet. Suggest a boot for protection and get a second opinion.

Sounds like: It was displaced from your discription if it had a space. Space may have been minor and heal anyway. Without looking at x-rays its difficult to say but follow your drs orders. If it still bothers you down the road then get it reevaluated.
