Based on what I see in Athens, based on the screams during physio and complications, and based on the forum comments, I think maybe its something like this:
I think technically someone who is doing femur internal + external tibia at the same time might be the most painful option but lets not include that situation because I don't know anyone who did it
Most painful: full externals frames (the metal cage with pins) based on the screams I've heard from the externals patient here and his description of his pain. the main thing is like during physio, his pain is not like even really that much from muscle stretching so much as pain related to the pins it seems
next most painful: probably LON?
I know that ISKD and Fitbone still exist but Betz does not like them because of corrosion problems + other doctors don't like ISKD for rate control issues I think? can't remember
Next most painful: Quadrilateral (ex: 4 nails in you lengthening), I feel like this is alot of stretching pain to do, even if its precise. I can't remember if Betz/Guichet ever do 4 clicking nails in someone but I imagine that would be short term more painful than precise (but clicking pain decrease as time passes I find)
if we rate pain on a scale from 0 to 10..
Next: I think clicking femur nails (gnail, betzbone, though rumor is betzbone might be easier to click than gnail) are in the short term more painful than precise, but I am not sure about the long term across the 6 months after the surgery. My clicking pain went from like 2 to 7 pain at first now down to like 0-1 pain after a few weeks, its usually about 0-0.5 pain now for gnail femurs for me. So I feel like in return for a few weeks of clicking pain, the rest of the months are easier compared to precise and my walking seems to be better (due to weight bearing for clicking nails) than the precise femur patient who got the surgery done around the same time as me. But yes clicking in the first weeks or so can be stressful
Next: probably precise femurs because of the femur muscle stretching
Next: hm... I think clicking tibias and precise tibias might almost be a tie, most people seem to say that clicking tibias doesn't hurt that much and in return you also can stand up which seems like less suffering in the long term during your recovery compared to precise tibias. I might be wrong. So I think it's another situation where precise tibias should be short term less pain than clicking tibias technically, but not necessarily by that much
Anyone wanna correct me?
With gnail femurs, the most pain I've ever had is during physio stretching (hamstrings and quads, mostly hamstrings). I described that pain as 8 out of 10 but maybe I should have rated it 10 like the guy above since it was the most physical pain I've ever felt in my life --and so maybe it should have been 10 by definition. The only reason I didn't rate it higher was because I was also hearing the screams of the guy doing externals and assumed my pain is probably less than his. Recently my physio stretching pain at about 1.5-2 months after the surgery has been closer to 6-7 out of 10 pain mostly
