Im guessing (that being the key word here) that providing its a hairline fracture, (I.E it hasnt bent the bone out of shape where its in 2 parts) and its all nice and straght still, and isnt likley to affect the joint, then strap it up etc. and get on with life. You break your toes all the time apparantly, and they still seem to function fine.... The doctor has spoken, listen to him, not me, I know f**k ALL.
