Hi, thanks for writing to HCM.
I just wonder why you have stayed for 12 years without undergoing surgery for the scaphoid fracture
if you know that it has not united.
Anyway, this is just to let you know that surgical results for a scaphoid nonunion
are always good if done within 1 year of time. As you have already developed arthritic changes as well, you cannot expect an excellent outcome after surgery.
So, Consult an orthopedic surgeon and discuss about the pros and cons of surgery.
Hope this information is helpful. Good day
