Hi, thanks for writing to HCM.
Non-union and Avascular necrosis
are frequent complications of scaphoid fractures
The only effective way of treating an established scaphoid nonunion
is by VASCULARIZED BONE GRAFTING
which will yield optimum functional results. But this procedure is really cumbersome and needs sugical expertise.
So, I suggest you to consult an orthopedic surgeon with good experience in handling these sort of injuries.
Hope this information is helpful. Good day
