The bend could be coz of multiple reasons:
1. nail being not too rigid- plasticity
2. its a monorail
3. retorgrade nailing? the femurs and the tibias have a slight curve close to the knee. therefore driving the nail along a curve path bending the inital alignment itself. I have seen such issues on inistal distraction to as much as large distractions.
I havent seen a precise 2 or stryde bend, I have seen few other nails bend even on antegrade femur insertion.
How much of a factor could retrograde nailing or doing LON with monorails contribute to the bending?
-
My precise nail 2.2 bent about 5 degrees, right at the junction of the small/larger transition mid nail, i wieghed 60kg at the time, then nail was extended ~ 8cm - this required immediate replacement with a solid rod.

Now i strongly feel most of the bending happen in retrograde or internal tibias. Although no medical literature that I could find on that.
May this could be opposed if we have had an antegrade femur nailing that has curved. Do we?

Ok....but first of all someone plz make me understand the technicality of this antegrade and retrograde thing🤔

Antegrade femur = insert through the hip (top of femur)
Retrograde femur = insert from knee area (bottom of femur)
