Hi and thanks for the query,
Success in such surgeries are greatly dependent on the identification and correction of the main cause of the non union or poor union. This can be from technical expertise errors, chronic disease, infection, Vitamin deficiency
and premature mobilization or utilization of the operated region.
Operations carried out by an experienced and competent team, with all the above conditions well considered could yield almost similar success rates as in first hand surgeries (over 90%).
I suggest you consult an experienced orthopedic surgeon in a setting that has the technical competence to carry out the surgical procedure. Respecting immobilization times by the client is of utmost importance. Thanks and kind regards.
