32yrs, 5'10, 165lbs. Considered healthy, non-smoker, drug or alcohol user. Feb 2nd I broke my m#5 in the "middle shaft".No fusion/non-union still, what now?

What does ortho say? If non-union occurs, may need surgical intervention. There are experimental use of electrical currents on joints where non-union has occurred - would ask your orthopedist about that, as well as making sure you are getting adequate intake of calcium and vitamin d, as well as good nutrition in general.
