Hey Unicorn, first of all best wishes for the recovery.
I just read your diary. I strongly believe your non-union may be that due to the reason that significant percentage of your original bone is occupied by the nail, leaving little of this bone to regenerate new bone. In other words as you said that initially the callus was forming but later in just backed down, this may tell that your existing bone mass could have formed new bone upto a certain length, when you crossed that limit the bones did not bother to fill the gap as if they knew they would not have succeeded anyways in fully bridging the gap.
So i just wanted to ask/suggest, did you consider either taking the rod out and putting instead a thin rod or reducing the distance between the segmens by shortening the rod(if that is possible) or any other method in which bones would not have to make so much of new bone mass. I know taking out and putting in rod could be really dangerous esp seeing your frail bones but I guess it would have saved you from lot of trauma..
Yes, thank you for your suggestion. That is the plan if my bone graft fails. The grafting method is THE LEAST invasive of the several solutions out there since it has been 2 years now and my 4th surgery.
Because my femurs were over reamed to ram in the 13mm nail, you're right, there are very little to no bone matrices/living cells left to consolidate. Hence, as you say it, it is too far for the calluses to bridge, so they can't even be bothered.
Hence, if this grafting fails, the surgeon will remove the large g-nail, and implant a thinner Precice Unyte that will be pre-lengthened to 8cm, and we'll slowly shorten me until my calluses join. And when it does, I will be lengthened back to 8cm.
We're just trying to avoid more unnecessary surgeries like shortening etc. because remember, my goal was not 10cm. It's because the g-nail cannot stop and cannot reverse. So when you suffer from non-union holding the nail in place, it can click very easily with every knee movement. Hence, my doctor called it runaway lengthening.
It has happened to another girl who had one non-union leg that ranaway too and unfortunately, because the leg length disparity is too much between the fused and non-union legs, she had to do a shortening surgery.
I'm just hoping this is my last surgery (besides the nail removal). I'm sooooo tired of myself and looking at my frankenstein scar riddled legs. Instead of celebrating my height, I'm purely exhausted from how much trauma it has caused me (mentally/physically) and how it's made my life a living nightmare
