The narration of ur case is unsufficient.
Kindly take into account the type and grading of the initial trauma,whether it was open or closed.
It you had a debridement performed, it already creates suspicsion of infection prior to it.
Implantation done at the time of an active infection, will only create a source of recurrent infection.
U need a radical debridement, implant free period,
Adequate skin cover or skin flaps, and later when there are no signs of active infection including lab test and local tissues conditions, you can go ahead with permanent fixation.
Do take into acccount that once infected, the chances of non-union increase substantially.
Take care
