He was a foot and ankle surgeon.
Was your doctor a foot and ankle surgeon, a general orthopedist, or podiatrist? If you have not seen a foot and ankle surgeon, that is what you might want to do to get a second opinion.There is a huge difference between a podiatrist and and foot and ankle surgeon (the surgeon has at least twice as much education and training). Preferable a foot and ankle surgeon from a teaching hospital. I hope this helps and good luck, achilles2
A slight edit, it was on the neck of the talus not the head.
