In reply to bubblewrap: the orthopaedic consultant/registrar/sho will or should take your job and hobbies into account when looking at treatment options. You could/should speak to them about it.
If its not a bad fracture and it has been reduced successfully there would be no need for surgery.
Where has I take it, your follow up X-ray it has shown that it hasn't reduced enough so may have a problem with malunion.
It isn't a matter of having x or y. It is dependent on how he fracture presents, is it intra articular, comminuted etc etc.
The options are cast, k wire which is less invasive surgery or open reduction and fixation.
Pro's & Cons to them all.
The hospital will often have a meeting to discuss all cases and as a team decide on the best treatment given all clinical details and information about that person.
Good luck with the rehabilitation, most people are their own worst enemy though when it comes to wanting to get back to do something too soon, which ends in longer away from the things you love doing! Listen to the physio and consultants!
