Smokers apparently do worse in surgery than non-smokers.. and it's of special concern in any surgery having to do with bones.
A study found that smokers can take nearly fifty percent longer to heal after foot or ankle surgery, and in some cases, their bones failed to heal at all.
Surgeons often ask smokers to give up the habit, at least for some period of time before surgery. It can affect healing in many ways.
