My son, an athlete, has a poorly healed clavicle fracture resulting in a lump on his shoulder.  He has pain in that area so a partial replacement of that clavicle bone is being considered; leaving essentially just the joints on each end in place and replacing the middle.

He is physically fit and very athletic. 

Is there a typical recuperation time from such a surgery?  I see that a simple facture healing time can be 6 to 8 weeks.  Would it be 'typically' similar to this?

Thank you
