I did mine and had a plate put in and then eventually removed. I think they meant you might be able to see signs of a union as soon as 2 weeks but they won’t do anything about it unless nothing has happened after 6 weeks.
My advice is read up on what you can change in your diet to aid bone growth (calcium tablets, apples, cut out caffeine and soda etc). It won’t necessarily do much but it will make you feel like you’re helping fix it which is beneficial psychologically
Also when you ask your physio when you can start biking again and he says x months don’t just sit around moping about it or worse start biking early and risk falling on it again. Instead ask the physio what activities you can do the soonest. Mine said swimming so I entered a long open water swim and spent 3 months training for that
