Radial nerve injury: What to expect?

I’m 26. Four months ago, I suffered a spiral humerus fracture that resulted in radial nerve damage. For three full months, I was completely unable to perform any hand movements controlled by that nerve. Things have finally started to improve recently, though progress is slow. While it’s a relief to see some movement at last, I’m curious if anyone here has dealt with a similar injury—specifically nerve compression or damage rather than a complete severance? How long did it take for you to reach full recovery, or at least get back to a point where the hand functions normally? Thanks!
