My 14 year old son has a now, non-union fracture of the lesser tuberosity of the humerus. I have read that this is a very rare fracture. when reading the MRI findings it appears that the subscapularis is unremarkable. He had a PRP injection done into the site of the fracture to see if this would stimulate bone growth but the x-rays at 6 weeks don't look as good as had been predicted. I'm trying to decide if it is best to wait and see if he heals or to have surgery done. I understand that this is an extremely rare fracture and I have had a difficult time finding a doctor who can deal with this. Do you have advice?
