Howdy,
I figured that was going to happen, but boy it sure didn't take long, eh?
AVN is possible but not all that likely in the area where you had your injury. It really depends upon the extent of the injury and and the possible damage to the vascular inflow to the first met.
I'd opt for the implant over the fusion. I just have a hard time with that stiff toe for the rest of your life. Too young for an implant? No, if the implant fail (which is unlikely) just pop another one in.
